iOS: Error message : <unknown>:0: error: unknown argument: '-enable-batch-mode' Command CompileSwiftSources failed with a nonzero exit code

If I downloaded the old swift compiler 4.0.3 (as the xcode 10 contains the 4.2), I have an error message in my project:

How can I desactivate that param : -enable-batch-mode
