Hi all!
I'm using Xcode - Version 8.0 (8A218a) and sometimes it will fail during a build and will give me this error message. I've had luck cleaning the folder, trashing the derived folered, and booting. This obvisouly is not a strategy the works for me in the long term. Any ideas on how to fix this?
I've also recreated this issue with Xcode - Version 8.1 beta (8T46g).
error: Task failed with exit 1 signal 0 {
/usr/bin/codesign '--force' '--sign' '-' '--verbose' '/Users/xxx/Library/Developer/Xcode/DerivedData/xxx-xxxxx/Build/Products/Debug-watchsimulator/TargetName Extension.appex/Frameworks/libswiftCoreGraphics.dylib'
}
