I\'m using XCode 6.2 and I have a project with several targets and with no tests.
I\'m trying to include now XCTest for one of the targets. To do so, I add a new \"Cocoa
In my case, target's iOS Deployment Target
in Build Settings
was lower than target device's version. Hope that helps someone.
I got this error today because I forgot to add sources to the "Compile Sources" build phase in my test target.
I finally managed to solve the problem. It was related to the compiler selected by default for the XCTest target. It had selected "Unsupported Compiler" and I changed to "Default compiler (Apple LLVM 6.1)" and it started working again.
