Test App on iPad get the following error: Task failed with exit 0 signal 4{

I used Xcode 9.3.1 and Mac OS High Sierra 10.13.4 The only thing I did is to add a label to the iPad storyboard to find out if testing on the device is possible. I have a valid apple developer account and choose iPad as device in Xcode.

error: Task failed with exit 0 signal 4 { /usr/bin/codesign '--force' '--sign' 'F3697********************************' '--verbose' '/Users/username/Library/Developer/Xcode/Build/Products/Debug-iphoneos/iPad_Test.app/Frameworks/libswiftCore.dylib' }

Did have everyone experience with this issue?

Thanks for your help
