MacBook cleans up disk space

Preface: As a programmer, after a long time using MacBook will inevitably encounter "insufficient disk space" warning, then you can clean up the following folder, you can generally clean up the size of dozens of G!

1. Delete the files from the "~/repository /developer/xcode/deriveddata/" directory, which is the middleware generated by Xcode during the compilation process, and the files are particularly large and can be deleted after compilation is complete

2. Delete the files from the "~/repository /developer/coresimulator/devices/" directory, which is the data of the emulator generated by Xcode when debugging the simulator, If the emulator is no longer in use, you can delete

PS: Not the Repository folder in the Macintosh HD directory, but the Library folder (a hidden file) in the user directory
