I’ll introduce how to solve the Multiple commands produce error that occurs in Xcode 10.
After updating to Xcode 10 and building, the following Error: Multiple commands produce error message was displayed.

:-1: Multiple commands produce '/Users/myname/Library/Developer/Xcode/DerivedData/myapp-xxx/Build/Products/Debug-iphonesimulator/myapp.app':
1) Target 'myapp' has create directory command with output '/Users/yourname/Library/Developer/Xcode/DerivedData/myapp-xxx/Build/Products/Debug-iphonesimulator/myapp.app'
2) That command depends on command in Target 'myapp': script phase "[CP] Copy Pods Resources"
That’s all from the Gemba where I solved the Multiple commands produce error in Xcode 10.
