Xcode 6 after deleting deriveddata, compile exception

First, the phenomenon

Xcode 6 compiles an exception and always reports that the project name directory cannot be found.

Ld:file not found:/users/dxxxdev/library/developer/xcode/deriveddata/xxxx-xxdfasdfasfasdoczqswzexnvbxai/build/ Products/debug-iphoneos/xxxx.app/xxx

clang:error:linker command failed with exit code 1 (use-v to see invocation)

Second, the reason

When the project was originally created, the use of the English name (the use of Chinese names will be garbled, that is, after the identify three short horizontal, can not be deleted).

After the project is created, change the name to Chinese.

Clear all deriveddata once, without any problems before clearing.

Iii. Methods of Treatment

1. Discard Test Build

Menu Product--scheme-->Edit Scheme

On the left, select the Build, and the right part of the red circle is unchecked.

2. Recovery method

Target - Build Settings-->packaging--and Product Module name to the original English name (that is, what file is not found in the error, you can change to what file name).

You can then change the name back to the Chinese name.
