Note:after Modifying system headers, delete the module cache at '/users/sumomochuufuku/library/developer/xcode/de Riveddata/modulecache/2nevap7x943d2 '

1 Error generated.

Workaround: Go to '/users/sumomochuufuku/library/developer/xcode/deriveddata/modulecache/2nevap7x943d2 this folder, delete the contents of its folder, Then run the app, no problem, note not delete the 2nevap7x943d2 folder, but the contents of it. And then clean the project. (Product, clean)

Attention:

1), Sumomochuufuku is my user name, you have to change to your own.

2), Nevap7x943d2 folder should be the corresponding application, so it will change with the app, to understand and flexible use.
