After updating to the latest version of Xcode at the moment (version 10.0) the project is unable to build because it found some errors regarding some "Command CompileSwift failed with a nonzero exit code" error.
How do I solve this errors? They appear in most of the Pods (I use CocoaPods) I use inside my project.
I have tried updating the pod version and the pods to the latest version available, but the problem is still there.
I have searched a lot through the web and there is very little information regarding this issue.
My problem was I had due to the non-existence of a native Switf CommonCrypto, used a bridging header and a target that with some magic included it in the build. Since CommonCrypto is now native, I solved the problem by removing the target and the #import and instead added a import CommonCrypto where I used it.
