my framework is not building

Hi!

I am creating an audio engine as a framework in Xcode 8 for iOS, but it does not build. It keeps giving me this error:



"Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1"


Could someone please help? I am not able to find the problem at all


Thanks
