I solved the problem.
The build was successful in xcode, so suddenly the build in the appcode was successful. I do not know why.
Anyway... Thank you~ :)
I updated iOS 11.2 and Xcode.
and.. AppCode is not working.. build.. clean...
I can't see any build log.. only... log is below..
AM 9:39 Build failed in 79ms
AM 9:42 Clean failed in 94ms
Does anyone know reason?
