Disable bitcode in iOS framework target by phatblat · Pull Request #506 · libgit2/objective-git (original) (raw)

This change explicitly sets the ENABLE_BITCODE build setting to NO to allow the build to work in Xcode 7. I've only had these failures when building ObjectiveGit for a containing app using Carthage on the command line; for some reason the build in the GUI still works. Regardless, the Xcode 7 release notes have been warning that when bitcode is enabled for a target (default is YES in the iOS 9 SDK), it will eventually be an error if anything that target links to does not also contain bitcode.

** BUILD FAILED **

👌 Xcode 6 doesn't know about the new ENABLE_BITCODE setting. It shows up in the User-Defined settings, but has no effect.
