Multiple errors after migrating to Xcode 10

Question

After updating to Xcode 10, I am getting the following errors in my project :

First error :

:-1: Multiple commands produce '/Users/maropost/Library/Developer/Xcode/DerivedData/MPPush-dorcxsyibrmjnndrycgblntogjan/Build/Products/Debug-iphoneos/MPPush.framework/Info.plist': 1) Target 'MPPush' (project 'MPPush') has copy command from '/Users/maropost/Documents/Work/iOS/Products/SDK/SwiftFromStart/MPPush/MPPush/Info.plist' to '/Users/maropost/Library/Developer/Xcode/DerivedData/MPPush-dorcxsyibrmjnndrycgblntogjan/Build/Products/Debug-iphoneos/MPPush.framework/Info.plist' 2) Target 'MPPush' (project 'MPPush') has process command with output '/Users/maropost/Library/Developer/Xcode/DerivedData/MPPush-dorcxsyibrmjnndrycgblntogjan/Build/Products/Debug-iphoneos/MPPush.framework/Info.plist'

Second error :

Could not delete /Users/maropost/Documents/Work/iOS/Products/SDK/SwiftFromStart/MPPush/build because it was not created by the build system and it is not a subfolder of derived data.

Third error :

Command PhaseScriptExecution emitted errors but did not return a nonzero exit code to indicate failure

Already checked this but unrelated.

Answer 1

For the below error:

Could not delete /Users/maropost/Documents/Work/iOS/Products/SDK/SwiftFromStart/MPPush/build because it was not created by the build system and it is not a subfolder of derived data.

According to https://developer.apple.com/documentation/xcode_release_notes/xcode_10_release_notes/build_system_release_notes_for_xcode_10

The Workaround is to Delete the build folder manually which is in your framework's project directory. Hope this helps!

Answer 2

I have fixed issues by enabling Legacy mode. Do follow the below steps it will help you.

In Xcode, Goto File -> Project/Workspace settings > Advanced -> Select Legacy

Please refer below screenshots for further assistance.

IMPORTANT NOTE:

CLEAN + BUILD & MAKE SURE YOUR DELETED DERIVEDATA FOLDER FROM TRASH

Check your Copy Bundle Resources in Build Phase, You should find some files(should be images in your situation) in that list twice. Delete them and rebuild them.
