I have the same error and just can't get any further. When I create info.plist, it is automatically in the copy bundles. If I remove it from there, the target membership is also gone. But if I add it, I always get the error message: Multiple Commands Produce Duplicate. So it seems that the file exists twice. In the derived data folder, there is also another info.plist (with a small i), which contains different data than in my actual Info.plist file. I have checked the code of my app in the text editor to delete Info.plist as well as the derived folder, but it always comes to the same error.
