  • 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

Open-Source Project of the Week

  • Extensions
    • What are they
      • Turns out…”Extensions” is not a single concept.  Multiple flavors known as extension points.
      • App Extension lets you extend custom functionality and content beyond your app and make it available to users while they’re using other apps.
      • App Extensions are a separate binary that runs independent of your app.
    • Extensions Points
      • Today – interact with the “Today” view of notification center
      • Share – Post to sharing website (twitter) or share content with others
      • Action – manipulate or view content within the context of another app
      • Photo Editing – edit a photo with Photos app
      • Finder (OS X only) won’t discuss
      • Document Provider – manager files
      • Custom Keyboard – replace custom keyboard
        • Apple is really stressing “Trust” as a key when creating a custom keyboard.  Your users are giving you access to everything they type including passwords and other sensitive data.
    • App extension must exactly match one of the types of extensions.  You can’t create a generic extension that matches more than one extension points.
    • What can’t they do
      • Access a sharedApplication object
      • Use any API marked in header files with the NS_EXTENSION_UNAVAILABLE macro
      • Access camera or mic
      • Perform background tasks
      • Receive data via AirDrop
    • Distribution
      • App Extensions must be delivered via a Containing App on iOS.
    • Common Needs
      • Sharing data with containing app requires special considerations.  Need to use a share container.  Watch out for data corruption/
      • Deploying to older version of iOS
        • Need to take advantage of conditional linking
        • Use dlopen command if systemVersion return iOS 8.0 or later

Mobile Accessibility – getting into the details

iOhYes Podcast Episode 35 – Includes a discussion with Neem Serra about the importance of making apps accessible

The basics

UIAccessibility protocol reference

Advanced APIs

UIAcessibilityContainer protocol reference

UIAccessibilityAction protocol reference

UIAccessibilityPostNotification() reference

Thoughts on accessible design

  • What considerations should be made in terms of information density?
  • How do we maintain accessibility as design trends toward gesture-driven UI?
  • How does one strike a balance between avoiding too many user preferences and providing adaptability for special needs?

Riemann Sum: UIAccessibility Demo – Sommer Panage on GitHub

The application allows the user to model one of 3 functions in a graph and select the number of rects to approximate the integral using a Riemann Sum. (This demo uses the Left Riemann Sum.)

This app has been made fully accessible to demonstrate the use of Apple’s UIAccessibility protocols / classes. It demonstrates basic accessibility additions via customization of accessibilityLabel properties thru more advanced accessibility via custom accessibility containers.
