The Discussion

  • WatchKit / Pebble
    • WatchKit design decisions: code runs in the phone, not on the watch. API is synchronous, but with no getters.
    • The big success of WatchKit is making the API transport-agnostic: no mention of Bluetooth.
      • It may even use Ad-Hoc Wifi to send larger amounts of data.
    • General confusion around the limitations of WatchKit:
      • It’s NOT the API to make watch apps, but a way to extend iOS apps by “projecting” data to the watch.
      • Native apps coming later.
    • A win of making watch apps extensions is that, at least for now, the user doesn’t need to manage which apps you install on the watch, eliminating one of the frictions of the Pebble.
      • Another consequence is it eliminates the need to log into apps separately for the watch, like you have to do with Pebble apps.
      • Apple needs to get App Store discovery right.
    • beta 2 released today (Dec. 10); API changes in 8.2b2
      • [WKInterfaceController +openParentApplication:reply:]
      • [UIApplicationDelegate -application:handleWatchKitExtensionRequest:reply:]
        • From the docs: “A dictionary containing data to return to the WatchKit app. The contents of the dictionary must be serializable to a property list file. The contents of this dictionary are at your discretion and you may specify nil.” (emphasis our own)
      • Default row appearance in WKInterfaceTable, which can be overridden by specifying bg color, margin, corner radius and height in IB
      • Blog post by _DavidSmith
    • Lister example app updated today w/ Watch extension (app and glance)

  • Tom Harrington – Sharing data between iOS apps and app extensions
    Overview of file-based data sharing. When I originally read this article and marked it as pick-worthy, there was considerably more information about how to use file coordination as a notification mechanism between apps and extensions. It turns out, Apple has specifically warned against using file coordination in extensions (Tech note 2408). The article has been updated accordingly.

 Open-Source Project of the Week

A great open-source resource was my classmates work on Github. We had to submit work using Github and it quickly became a great resource for looking at other classmates’ code. If you search for “CodePath” and filter for Swift on Github, you’ll find many of the designer and engineering assignments for the Swift classes.

  • Dash API Docs for iOS
    The API documentation you know and love from OS X is now available as an iOS app. Personally, I don’t find myself searching API docs on mobile devices all that frequently, but I see this as another way to support Bogdan Popescu’s efforts. I use the Mac app all the time.

 Open-Source Project of the Week

2048, An open source version of the game “2048”

git clone https://github.com/ik/2048.git

Is this damaging to the original developer of the game or does this follow the old adage, “There’s no such thing as bad publicity”

Darryl’s opinion:

  • Article on the “Threes ripped off by 1024, which is in turn ripped off by 2048” “controversy”: 2048’s Massive Popularity Triggers Cloning Controversy – Kotaku
  • At what point does a game define a new genre, which makes cloning inevitable? If game mechanics vary slightly, is that enough of a distinction? (I think so, but there are many who would consider the game mechanics to be every bit as much of the “art” as the game’s content.)

Jason’s opinion:

  • The market usually doesn’t care about fairness. Being an indie developer means running a business. Businesses must always be evolving to “put themselves out of business” or else your competitors or copycats will.

  • Metal – Low-overhead GPU access for iOS 8
    • What is Metal?
      • Modern, Thin API for GPU programming (graphics and simd compute)
      • Designed for A7 and newer SoCs (iPhone 5S and newer)
      • Shader/kernel language based on C++11
    • Who should/will use Metal?
      • In-house/roll-your-own 3D engines/frameworks
        • For most folks, using Metal or OpenGL directly is overkill (but fun!)
        • Alternative, higher-level APIs include SceneKit (3D) and SpriteKit (2D), which provide much more than just graphics rendering support, including graph management
      • Third-party 3D engines/frameworks
      • Compute-heavy applications and filters with highly parallelizable work
        • DSP
        • Image filters
        • Protein folding?
        • Note: Swift currently doesn’t support importing C unions or SIMD vector types. Chris Lattner acknowledged this, citing feature prioritization (so it’s reasonable to be hopeful it’s coming in the not-so-distant future). In the meantime, if you need to work with SIMD, you may want to stick with Objective-C when using Metal.
    • Practical differences between Metal and OpenGL ES
      • In Metal, command buffers are exposed, giving control over when the commands are sent to the GPU to the application and putting the onus of asynchronous framing on the application
      • Most state is stored in immutable state objects that are created at setup, not in each draw cycle, allowing for quick state change that doesn’t require expensive recompilation of shaders/validation
      • Streamlined API. OpenGL provides many ways to do (effectively) the same task largely due to its evolution. Metal sheds many of the legacy techniques.
      • Metal provides direct access to the A7’s shared memory. Thread safety/synchronization is the responsibility of the app.
    • Additional resources
