Error compiling swift with ninja

Hi, I'm having problems when compiling swift, it fails when start compiling swift, the previous steps compile without a problem.

I execute the following:

./utils/build-script --release-debuginfo --debug-swift -c

Compiles llvm & cmake without a problem. But when start to compile swift it fails with this error:

I don't know if is useful, but the CMakeError.log in the swift-macosx-x86_6 is the following:

Supposedly adding --xcode parameter should fix it for the build-script: Swift compilation failed

I'm also facing it, but I'm facing it when building toolchains: ./swift/utils/build-toolchain

I'm not sure how to add this parameter to that. Any suggestions?

I don’t want to compile with xcode. I want to use ninja.

Edit: building toolchain doesn’t support (I believe) Xcode.
