Xcode "Cannot parse contents of Info.plist"
This is one of the best way to detect on which line the error is occurring.
Just go the directory where the plist file is present then write this command on terminal->
plutil filename.plist
Another cause of this issue can be from attempting to put URLs (really just slashes etc.) in your app-Info.plist.
Get around it by simply raising the -traditional flag inside of the Info.plist Other Preprocessor Flags option in your project build settings.
I think you have used source-control tools, you can use basic text-edit tool without Xcode to open this plist, command + F to find "<<<<<" or ">>>>>", then you will probably find error string such as:
<<<<<<< .mine>>>>>>> .r605select the correct string, and delete the other one, error is resolve!
