Xcode 6.3 is crashing on Project Rename

Question

I just updated my Xcode 6.3. I am getting an issue while project renaming. Is there any solution?

And in some case it is showing mymac instead of simulators or devic

Answer 1

Manually rename in the finder App.xcodeproj and App-info.plist to YourNewAppName.xcodeproj and YouNewAppName-info.plist. Control click on YourNewAppName.xcodeproj and chose Show Package Contents, manually rename App.xcscheme to YouNewAppName.xcscheme

Open project.pbxproj, YouNewAppName.xcscheme and xcschememanagement.plist files in your favorite text editor other than Xcode. Find and replace one at a time all instances of App to YourNewAppName then Save.

Control click on project.xcworkspace and chose Show Package Contents and open UserInterfaceState.xcusersate in text editor. Find and replace one at a time all instances of App to YourNewAppName then Save.

Open YourNewAppName.xcodeproj in Xcode and change under the Project Document settings: Project Format Xcode 6.3-compatible

...or for an easier time go back to Xcode 6.2.
