| I posted this on the xcode-users list, but I suspect it is more likely to be read by accessibility engineers here.
I am concerned about an ambiguity in the Xcode 7 Release Notes regarding bitcode and applications that use dynamic frameworks.
The Release Notes say, without any stated exceptions, that framework and library providers need to include bitcode for Xcode 7 development. They go on to tell developers who use third-party frameworks, without any stated exceptions, that frameworks and libraries include bitcode when built for Xcode 7 development. They advise framework and library developers to distribute two versions of their products so they can accommodate clients built using either Xcode 7 or Xcode 6 because Xcode 6 does not tolerate bitcode well.
Bitcode is only relevant to applications sold in the App Store, as I understand it. However, the frameworks that I distribute use the accessibility API, and they are embedded in clients that are assistive applications for computer users with disabilities. Applications that use the accessibility API, including those that embed my frameworks, are absolutely ineligible for the App Store per Apple's rules. The App Store therefore provides no reason for me to implement bitcode in my frameworks, or to go to the trouble of distributing two versions of my products.
I assume that the statements in the Xcode 7 Release Notes are merely a simplified warning for the general case of applications built for the App Store using Xcode 7, and that my customers can in fact use Xcode 7 to build assistive applications even if I supply my frameworks to them without bitcode.
Does anybody know if Xcode 7 can be used to develop applications without bitcode? The Release Notes talk only about frameworks. They outline ways to strip bitcode from frameworks and to use Xcode 7 to build frameworks without bitcode for use in client applications developed in Xcode 6 by setting ENABLE_BITCODE=NO. What I wonder is whether setting the ENABLE_BITCODE build setting to NO will work for applications as well as frameworks.
