I had this problem too. Basically, go to the main project at the top of the Project Navigator, select on the Target in the "Targets" field, go to General, and select Choose Info.plist File under Identity. Here, choose the Info.plist file and select "choose". Rerunning the file will make it work. Note that you should change all instances of the old project name. This is a super old StackOverflow - https://stackoverflow.com/questions/33370175/how-do-i-completely-rename-an-xcode-project-i-e-inclusive-of-folders post that will (sort of) help you in renaming your entire project properly. I hope you understand.
