If you change the target's name.....

Many times we need to change the target name not the project's name, but after we change target name, compile on simulator has no issue, but if compile on device, there will a issue:

ld: file not found: linker command failed with exit code 1 (use -v to see invocation)

so how to fix it? 

You just need to manage the scheme, and add a new scheme for the current target with new name.

Thanks,
