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/Containers/Data/Application/1CAB64C8-D730-427B-8E9E-BD5E152ACFD6/tmp/IDEBundleInjection.framework/IDEBundleInjection' because no suitable image found. Did find:

I'm using XCode 7.0 and testing on an iPod running iOS 8.3. I have deleted the derived data and I've restarted XCode and it still hasn't worked.
In General Panel , not leave the Team to "None"
At Same time : select the code sign in Build Setting->Code Signing-> Code Signing Identity
I managed to fix this by specifying my developer certificate in build settings->code signing identity.
I fixed this by just creating a new UnitTest target, copying everything over, and removing the old one.
I fixed this by selecting the correct target and then selecting the correct Code Signing Identity from Settings. It was set to a non default - changed to 'IOS Developer' for the Debug setting entry.
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:

I had this same issue and had to reboot my device. I was using iOS 10 with Xcode 8.0 (developing in swift 3.0)
I needed to set the team under Project->App Target->General. It was set to "None", instead of a valid team.
I had my base SDK in XCode Build Settings set to a more recent version of iOS than the phone had, so I had to upgrade the OS on the phone.
I fixed this issue by rebooting my iOS Device.
