New warnings in iOS 9: "all bitcode will be dropped"
I have this new warning about the Google Framework in my app:
(null): URGENT: all bitcode will be dropped because '/Users/myname/Library/Mobile Documents/com~apple~CloudDocs/foldername/appname/GoogleMobileAds.framework/GoogleMobileAds(GADSlot+AdEvents.o)' was built without bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. Note: This will be an error in the future.
Xcode 7 is giving me around 204 warnings about this same concept, and I could not get around with this. Also I have a problem accessing the network from my app. This is the error from the Debugging Area:
-canOpenURL: failed for URL: "kindle://home" - error: "This app is not allowed to query for scheme kindle"
All of these problems were not present in iOS 8.
Answer
Your library was compiled without bitcode, but the bitcode option is enabled in your project settings. Say NO to Enable Bitcode in your target Build Settings and the Library Build Settings to remove the warnings.
For those wondering if enabling bitcode is required:
For iOS apps, bitcode is the default, but optional. For watchOS and tvOS apps, bitcode is required. If you provide bitcode, all apps and frameworks in the app bundle (all targets in the project) need to include bitcode.
