Discussion: Time Profiler But first: a brief rundown of the Instruments UI Toolbar Record/Stop Pause Target Selection Status display Strategy Selection CPU data Instrument data Thread data Detail/inspector toggles Timeline Plots data along the time your app was sampled Can be filtered and zoomed Disclosure arrow can toggle display of just the current run or of all runs in the trace document Detail Contents vary by Instrument, but this will generally be a table with some representation of the sampled data Inspectors Record Settings Display Settings Extended detail (often the heaviest stack trace) What is Time Profiler? An Instrument providing sample-based analysis of an application’s activity Periodically samples the call stack to determine where an app is spending its time These are instantaneous samples. They don’t track the duration of a function call, but rather how many times when sampled was the application currently in said function call. No distinction between a fast function called many times and a slow function called few times Extremely fast functions may not get sampled at all, if they happen to occur in between samples Provides a detail view listing call trees, optionally separated by thread and/or state, allowing the developer to drive down into calls to identify areas that may need to be optimized Weight - Percentage of samples in which a function appeared and an aggregate summary of samples (count * sample interval) Self Weight - Aggregate summary of samples in which the function was at the top of the call stack Symbol Name - The thing represented in the current row (may be a function, method, closure/block, thread, or app) Category Additional columns available: Count Self Count Library Picks John SelfControl Darryl WWDC 2016 Session 418 - Using Time Profiler in Instruments Alternative show title suggestions Try harder n squared complexity my code, vs not my code expected or unexpected notion of runs This episode sponsored by Braintree…

Allows you to process the payload of a push notification before it is presented (eg: end-to-end encryption or notification attachments). Use in conjunction with “mutable-content: 1” in the aps portion of an APNS payload. UserNotificationsUI Framework Provides the UNNotificationContentExtension protocol View controllers adopt this protocol, using the VC’s view to display the notification contents Custom content is sandwiched between a header with the application icon and title and the default notification payload (default payload can be hidden using an attribute in the Info.plist) No user interaction Actions are displayed and extensions can respond to them by intercepting action responses Protocol provides a didRecieveNotification: method you can use to set up UI in response to the notification Picks Darryl New Swift, Core Data and Cocoa Books - Use Your Loaf John List of Public Slack Groups Mr Robot returns to USA Network July 13 This episode sponsored by Braintree…

Discussion Testing normal networks (aka, not the US) 62.5% of the world’s 3.2 Billion internet users have 2G connections (or worse). That number is growing. LTE speeds aren’t going to catch up for at least a decade if not much longer. When building robust networking between your client apps and your services, the common case should be the default case. AKA: not WiFi and not LTE. Things that help a great deal: Test on 2G and flaky networks Helps to do real world testing in parking garages, elevators and in transit. Simulation will be the highest reproducible ROI way to test Fail fast and accurately. Timeouts play a part in this. Be dynamic with how you handle the network. Slower speeds should have less networking Use modern tech, like HTTP/2 Defer, defer, defer (and prioritize) Robustly handle errors If at first you don’t succeed, try again! And again and again. Retry policies can get you from one-9 of success to three-9s very simply. Design your network API in a robust manner! Simulating bad connections: Using Network Link Conditioner - iOS and Mac Simulation over WiFi with router firmware Simulation by throttling via your network services with custom headers Simulation in your app by controlling the flow of data being received Expert mode: drop down to the TCP level! Timeouts List of timeouts: TCP: connection timeout (TLS connection timeout too), SYN timeout, keepalive/idle timeout, retransmission timeout NSURL: request timeout (max time between data being received in response - default is 60 seconds), resource timeout (time for entire transfer to complete - default is 7 days) Custom timeouts: transaction timeouts (time from initiation to completion including redirects and retries), queue timeout (how long can the request be queued without starting before it times), idle timeout (how long can a request do nothing regarding upload or download before timeout) NSURLSession has a problem with scale. Every different configuration setting requires another NSURLSession to be maintained and managed. Timeouts, different default headers, different TLS settings, different cookie settings, different NSURLCache, cellular vs non-cellular Robust API design Transactional APIs Robust error codes (not just HTTP status codes!) Retry policies to the rescue Picks Darryl Pain Free Constraints with Layout Anchors - A bit of follow-up from last week’s episode.

Discussion Auto Layout Stack Views, FTW (Auto Layout without constraints) (New in iOS 9, similar to what’s available in watchOS and NSStackView, which is available from OS X 10.9) UILayoutGuide New in iOS 9 Defines a rectangular geometry that can interact with Auto Layout Eliminates the need (in many cases, at least) for views that are included solely for layout purposes (container views, spacing views, etc) Views can still provide a greater degree of encapsulation Provide anchors that can be used to generate constraints Anatomy of constraints The layout of your view hierarchy is defined as a series of linear equations. Each constraint represents a single equation. Your goal is to declare a series of equations that has one and only one possible solution. Two basic types of attributes Size attributes (for example, Height and Width) Location attributes (for example, Leading, Left, and Top) The following rules apply: You cannot constrain a size attribute to a location attribute. You cannot assign constant values to location attributes. You cannot use a nonidentity multiplier (a value other than 1.0) with location attributes. For location attributes, you cannot constrain vertical attributes to horizontal attributes. For location attributes, you cannot constrain Leading or Trailing attributes to Left or Right attributes. Rule of Thumb for clarity Whole number multipliers are favored over fractional multipliers. Positive constants are favored over negative constants. Wherever possible, views should appear in layout order: leading to trailing, top to bottom. Constraint Priorities 1000 is required < 1000 is optional Intrinsic Content Size Content Compression Resistance Content Hugging Debugging Auto Layout Error Types Unsatisfiable Layouts. Your layout has no valid solution. Usually 2 or more required constraints conflict Ambiguous Layouts. Your layout has two or more possible solutions. * Need additional constraints conflicting optional constraints Logical Errors. There is a bug in your layout logic.

Motivation / Staying Productive Flow Mihaly Csikszentmihalyi Flow theory postulates three conditions that have to be met to achieve a flow state: One must be involved in an activity with a clear set of goals and progress. This adds direction and structure to the task. The task at hand must have clear and immediate feedback. This helps the person negotiate any changing demands and allows them to adjust their performance to maintain the flow state. One must have a good balance between the perceived challenges of the task at hand and their own perceived skills. One must have confidence in one's ability to complete the task at hand. Clear Distractions What things easily distract you when you need to get work done Make a list of these things Twitter, imgur, reddit, tv, music Clear these distractions Use a distraction free setting Get comfortable Change your setting Pairing Workout metaphor Hard to slack Intensity Don't have to do it every day Just 5 minutes I use this technique with my kids for studying 5 minutes doesn't really work for me Instead I say write 5 lines Sunk cost fallacy works in our favor I'm already here.

Discussion - Energy Efficiency for iOS Apps Apple’s Energy Efficiency Guide Are you telling me I have to worry about my app’s power consumption? This is iOS. I thought Apple was taking care of that for me...right?? What is Energy? Power is an instantaneous measurement of energy at any given point in time Energy is power used over time (Joules measured over watt-hours) Low power used over a long(er) period of time can amount to the same energy expenditure as short bursts of high power (more on this later) Major sources of energy consumption/power draw Device wake Aside from being powered off, a device in its sleep state is consuming the lowest amount of energy possible Whenever possible, avoid preventing the device from sleeping or forcing it to awaken Use technologies like push and background tasks judiciously CPU Usage An idle CPU uses ~10x the power of a sleeping CPU Just 1% CPU use costs 10% more than idle 10% CPU use costs 200% that of an idle CPU 100% CPU can result in 1000% (10x) power draw compared to idle Networking / Bluetooth Graphics/animation/video Sensors Location (Wi-Fi/GPS) Accelerometer Gyroscope Magnetometer Disk IO.

Permit the customer to become attached to a product that when the trial ends they realize they want to pay for it. Permit upgrade pricing Devs can’t just support the same version forever, permit them to discount the cost of upgrading from a previous version so they maintain brand loyalty Example: Version 1 was $10, Version 2 comes out and is $10. Having Version 2 be an upgrade from Version 1 for $5 would really be a value to loyal customers. Permit devs to address their customers’ concerns/reviews Example 1: Customer: Hey! The app doesn’t install when I download it, what a junk app! Dev: I’m sorry that you aren’t able to install! All installs are managed by Apple and a failure to install usually means there is an issue with the new version of the app propagating through Apple’s CDNs and it will take some time for the CDNs to hydrate properly for the install to work. Here’s an Apple support email address for you to share your concern! Example 2: Customer: Hey! I can’t log in anymore! I hate this app! Dev: I’m sorry to hear that, can you provide me your login name or email and I’ll be happy to look into this for you. Good suggestion. The Google Play Store lets you do this.

King Bluetooth is said to have united the Danish tribes into a single kingdom. The logo is a bind rune forming the initials H. B. (sort-of) Versions 1.2 1 Mbps data rate, > 80 kbps application throughput Probably the first version considered “viable.” 2.0 + EDR 3 Mbps data rate, > 80 kbps application throughput 3.0 + HS 24 Mbps data rate, but not really: The connection is negotiated over a BT link, but 802.11 is used for data transfer 4.0 (Classic and HS) & 4.0 LE (Branded as Bluetooth Smart) 24 Mbps data rate, but not really: See 3.0 + HS and LE has extremely low throughput by design (like less than 100 kbps) Bluetooth LE Totally new protocol specifically designed for low energy consumption and simplified communications Peripheral devices can implement just LE, just Classic or both Bluetooth LE and Core Bluetooth Core Bluetooth provides a layer of abstraction over the GATT profile (Generic Attribute Profile) Peripherals are “servers” Centrals are “clients” Peripherals serve one or more Service(s) Services have Characteristics (can be thought of as attributes or properties) Characteristics have a value, which may be readable, writable or notifiable Using CBCentralManager Instantiate the manager and then check for availability (implement the -centralManagerDidUpdateState: delegate method and check for PoweredOn state Scan for services with service UUIDs you provide using -scanForPeripheralsWithServices:options: When peripherals are discovered, the -centralManager:didDiscoverPeripheral:advertisementData:RSSI: delegate method will be called Connect to a peripheral using -connectPeripheral:options:, which in turn will call the delegate’s -centralManager:didConnectPeripheral: method. At this point, you can start using the peripheral directly. (And get responses through the CBPeripheralDelegate protocol) Discover services with -discoverServices:, which will result in the delegate’s -peripheral:didDiscoverServices: method being called Similarly, discover characteristics of a service using -discoverCharacteristics:forService:, from which you can expect a -peripheral:didDiscoverCharacteristicsForService:error: message Depending on the peripheral’s configuration, values for a characteristic can be read, written to or monitored for changes (notified) Characteristic values are expected to be small. (Like 20 bytes or smaller.) If you need to send larger payloads, it’s possible to roll-your-own streaming protocol atop characteristics. I don’t really recommend this, but it’s a fairly common approach I suspect some of this comes from the legacy of BT being treated as a dumb serial link Apple has recognized this trend and in recent versions of iOS/OS X, they have tried to accommodate higher throughput by negotiating higher MTUs when possible.

Through actionable examples, relatable stories, and constant experimentation she helps companies create more compassionate teams and vastly improved digital products. She also coaches individuals experiencing career stagnance or burnout, she writes, speaks, podcasts, YouTubes, and is an independent mom. Jaimee made this career shift by applying her typical process for designing a product (website or app) to her life, as if her life were the product. (Sometimes she tried Agile methodologies, UX methods, etc.) She started out with smaller objectives and working through side projects to clear obstacles (aka: excuses) from her path. Jaimee continues doing that through her monthly challenges, which have become playful and exploratory things that grow different skill sets and push her own boundaries of fear and comfort.

Note: The conference Ashton spoke at that Darryl mentioned is DevWorld. He spoke about designable and inspectable views. Ashton’s slides/code can be found here: https://github.com/Ashton-W/devworld-designables Discussion What are some nice patterns or not-so-nice anti-patterns/bugs you notice in iOS apps? How can devs go about fixing those problems? Nolan notices Requiring login/signup to use the app My wife’s personal pet-peeve Old Fab.com app vs Zappos app Suboptimal table views Stuttering Get off the main thread: includes networking and UIImage rendering Content flashing in once it scrolls into view Prefetch content before it comes on screen: can be easy with table view buffering Requesting all permissions on first app launch with no context! On demand prompting Interstitial Even better: don’t indicate they will be prompted, rather outline the feature and why it needs the permissions and have the user explicitly ask to grant permissions (Periscope does something like this ) Example: (User selects post a photo) Prompt says something like: “A picture is worth a thousand words. We’d like for you to be able to share any of you iPhone’s photos. By enabling us to access your photo library, you can choose from photos you already have to share with friends and family.” Below is a empty checkmark with text “Enable access to photo library” and below that is a “Close” button. Hitting the checkmark will ask for access and user knows exactly why they were prompted. Hitting close will save the setting as “on” or “off” based on if the checkmark was successfully checked. Chad notices Social login (FB/Twitter) only to ask for username/password/email afterward anyway Bad pull-to-refresh implementations (Apple, Twitter) Darryl notices Lack of accessibility Not conforming to the design language of the platform (Note that I didn’t say HIG) Re-inventing system-provided controls/mechanisms for the provider’s gain, not the user’s Facebook/Twitter/SocialMediaX sign-in as the only option Crappy validation.

This allows decorative views to be added directly to subviews without affecting the arrangement. Potential pitfall: Removing a view from the arrangedSubviews array does not remove it as a subview. The stack view no longer manages the view’s size and position, but the view is still part of the view hierarchy, and will be rendered on screen if it is visible. Multiple distribution styles UIStackViewDistributionFill - A layout where the stack view resizes its arranged views so that they fill the available space along the stack view’s axis. When the arranged views do not fit within the stack view, it shrinks the views according to their compression resistance priority. If the arranged views do not fill the stack view, it stretches the views according to their hugging priority. UIStackViewDistributionFillEqually - A layout where the stack view resizes its arranged views so that they fill the available space along the stack view’s axis. The views are resized so that they are all the same size along the stack view’s axis. UIStackViewDistributionFillProportionally - A layout where the stack view resizes its arranged views so that they fill the available space along the stack view’s axis. Views are resized proportionally based on their intrinsic content size along the stack view’s axis. UIStackViewDistributionEqualSpacing - A layout where the stack view positions its arranged views so that they fill the available space along the stack view’s axis. When the arranged views do not fill the stack view, it pads the spacing between the views evenly. If the arranged views do not fit within the stack view, it shrinks the views according to their compression resistance priority. UIStackViewDistributionEqualCentering - A layout that attempts to position the arranged views so that they have an equal center-to-center spacing along the stack view’s axis, while maintaining the spacing property’s distance between views. If the arranged views do not fit within the stack view, it shrinks the spacing until it reaches the minimum spacing defined by its spacing property. If the views still do not fit, the stack view shrinks the arranged views according to their compression resistance priority.

Tweet Shoutouts @dh_thomas @jazzychad @iOhYesPodcast In the last few years I’ve been of the mindset that models should be dumber. Easy to bloat them. — Amro Mousa (@amdev) July 22, 2015 @iOhYesPodcast how come show notes aren’t as detailed as they once were. Would always go there for Twitter names and Pick links ???? — Ashton (@AshtonDev) July 23, 2015 @iOhYesPodcast I’m using CoreData just fine from a framework written in Swift for bike2Go (for Philly bike share) https://t.co/IBcRpXT9O6 — Andy Obusek (@obusek) July 23, 2015 @iOhYesPodcast found you guys a month ago and love the show! But now I'm all caught up on new episodes and am having withdrawals #iOhNo ! — Dale Fairclough (@faircoder) July 25, 2015 @iOhYesPodcast I haven't had any issues using it, but to be fair my model is **very** simple. — Giovanni Lodi (@mokagio) July 26, 2015 @iOhYesPodcast Wait... we still don't have .contains on Swift arrays without using a protocol? NSMutable FTW. Again. http://t.co/ff7a8RwwOP — Ding0 Bytes (@ding0bytes) July 27, 2015 Discussion Programmer vs. Developer vs. Engineer discussion Re: Episode 76 Episode 76 had a great topic that was really thought provoking regarding Programmer vs Developer vs Engineer. Everyone can probably has an opinion on what those titles mean Fascinating: we’re inclined to rank things Their all title for someone who makes software or code Maybe “Software Producer” or “Talent” is less biased Code Poet is my favorite (thx John) Alternate views Instead, I like to examine the skills Instead of Programmer vs Developer vs Engineer; look at Programming, Development and Engineering as buckets of skills Full-time Equivalent The 5 skills Hacking * bringing together a system of potentially disparate computer apps/tools/functions to achieve a goal * Gluing together anything you can get your hands on to build a workflow or solution takes talent and skill * Often the goal of Hacking is really “discovery” or “exploration” Movie Reference: Hackers Programming writing code/scripts to pull together potentially disparate functionality and/or frameworks to achieve a goal You create a whole that is more valuable than the sum of its parts amassing and consuming huge amounts of knowledge about APIs and Frameworks that are available and then using them effectively Development the process of bringing together talent, ideas and requirements to build a new application or feature Deals with other people and takes input from all over to build something new it’s inherently collaborative and requires other skills like interpersonal skills and communications skills often called soft skills which I find ironic because it’s so hard Engineering the use of science and creativity to solve complex problems It needs an academic foundation combined with creativity and ingenuity to solve hard problems These skills get amplified in value when complemented by others who can fill in any knowledge or skill gaps Architecture the design of a large complex system or application that requires numerous contributors to fully implement it is a skillset that can envision, design, and clearly document and communicate a complex system in a cogent way that everyone tasked with implementing the system are able to apply their skills to succeed with little or no impediment? Picks Darryl Swift’s Type System - Ole Begemann A response to Brent Simmons’ blog post, Solving Problems I Don’t Have, Except that I Do Have Them , in which he points out the things he likes most about Swift, of which static type checking is probably the least significant.
