  • Introduces AS_AVAILABLE_IOS(x) macro.
    • When possible, evaluates to __builtin_available(iOS x, *) – same as @available but valid in C/C++.
    • Otherwise evaluates to the runtime version check AS_AT_LEAST_IOSx – checking CFCoreFoundationVersionNumber.
  • Changes our attributed accessibility implementations not to use KVC. Instead we check both the SDK version and the runtime version. It's a little ugly but it's correct on both versions of Xcode, and it scales better (and faster!). cc Use Xcode9 API For Attributed Versions Of accessibilityLabel, accessibilityHint, accessibilityValue #642 which does some of this same stuff.
  • Removes an old #if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_6_0 check. Sorry iOS 5 SDK users 😢
