I use Xcode 8.1 and after adding CocoaPods and Objective-C files to my workspace I can't run app on my device. This is error from console:
dyld: Library not loaded: @rpath/libswiftCore.dylib Referenced from: /var/containers/Bundle/Application/EAB92875-7A43-4DA0-8CB8-1C95A3AAF8EE/See My Progress.app/See My Progress Reason: no suitable image found. Did find: /private/var/containers/Bundle/Application/EAB92875-7A43-4DA0-8CB8-1C95A3AAF8EE/See My Progress.app/Frameworks/libswiftCore.dylib: code signing blocked mmap() of '/private/var/containers/Bundle/Application/EAB92875-7A43-4DA0-8CB8-1C95A3AAF8EE/See My Progress.app/Frameworks/libswiftCore.dylib'
I have tried recreating signing certificate, enabling/disabling Always Embed Swift Standard Libraries, clearing and reinstalling Xcode. Nothing helped
