\"Invalid IPA: Couldn\'t find executable specified in Info.plist - check the value of your CFBundleExec
I had the same problem, but I've solved it. It has to do with your architecture settings. In your target and project build settings all of your build settings must be set with armv 7.
In Target -> Build Settings:
Architectures = Standard(armv7, armv7s) - $(ARCHS_STANDARD_32_BIT) Valid Architectures = armv7 armv7s
Likewise for your project build settings.
Hope this helps.
