Since upgrading to Xcode 7.3.1 I cannot run my old apps on my iPhone. The build fails at:
/usr/bin/codesign --force --sign BE009CA490D248994BC926A8B8674F4133C8DDD6 --preserve-metadata=identifier,entitlements --timestamp=none /Users/me/Library/Developer/Xcode/DerivedData/MyOldApp-elxwfvyezlegongupbpyneiyxpuf/Build/Products/Debug-iphoneoswith the error:
/Users/me/Library/Developer/Xcode/DerivedData/MyOldApp-elxwfvyezlegongupbpyneiyxpuf/Build/Products/Debug-iphoneos: bundle format unrecognized, invalid, or unsuitable
Command /usr/bin/codesign failed with exit code 1I've been searching for some further explanation of what this actually means - narrowing down if the bundle is 'unrecognized', 'invalid', or 'unsuitable' would help Apple! Plus, the error message 'Command /usr/bin/codesign failed with exit code 1' seems to crop up for all sorts of other reasons.
I can run the apps fine on the simulators. And I can run Apps newly created in Xcode 7.3.1 on my iPhone, just not any that were created in earlier versions.
Any help would be much appreciated!
