Xcode 7.0 XCTest dyld: could not load inserted library IDEBundleInjection

Question

I\'m running unit tests on my iOS project and when it\'s running, it crashes and spits this out:

dyld: could not load inserted library \'/private/var/mobile/         


        

Answer 1

In my case there was nothing wrong with the provisioning profiles, it was down to the Architectures in the project excluding arm64. Once arm64 was added to both the test target and the host app target the tests ran fine (On Xcode 7.2). The error was:

dyld: could not load inserted library '/private/var/mobile/Containers/Data/Application/A94F5AD3-2A5F-415D-B127-0F45DEC7A659/tmp/IDEBundleInjection.framework/IDEBundleInjection' because no suitable image found.  Did find:
