I keep getting a warning for multiple build commands regarding .png files for my iOS project

Question

Warning: Multiple build commands for output file /Users/nroldos/Library/Developer/Xcode/DerivedData/artistreeApp-fnivhzlzlmkerwhdwwfnelzldkqx/Build/Products/Debug-iphonesimulator/artistreeApp.app/[email protected]

Warning: Multiple build commands for output file /Users/nroldos/Library/Developer/Xcode/DerivedData/artistreeApp-fnivhzlzlmkerwhdwwfnelzldkqx/Build/Products/Debug-iphonesimulator/artistreeApp.app/[email protected]

And so on...

Anybody know what these warnings mean? I would try to explain this more but I don't have a clue where these multiple build commands come from. I have only one view controller where I call for these .png files

Answer 1

Xcode complains with this type of warning when it is confused. What happens is that project has more than one files with the same name and Xcode doesn't know which one to compile.

Solution: Search for the resource under Copy Bundle Resources and remove the duplicate entries.

Steps:

1. Open theCopy Bundle Resources on Build Phases tab.
2. Find duplicate entries of the same files in that list.
3. Delete the duplicate reference.

Answer 2

Open the Copy Bundle Resources on Build Phases tab. Find duplicate entries of the same files in that list and Delete the duplicate references.
