swift compile error (custom toolchain)

[codetronik]

When I try to build an ios app on Xcode, I get the error below.
Could not parse Swift versions from: Swift version 5.9 (swift-5.9-RELEASE)

I checked the version of custom toolchain.

% /Library/Developer/Toolchains/My.xctoolchain/usr/bin/swift --version
Swift version 5.9 (swift-5.9-RELEASE)
Target: arm64-apple-macosx13.0

Below is the version of the Xcode's original toolchain.

% swift --version
swift-driver version: 1.87.1 Apple Swift version 5.9 (swiftlang-5.9.0.128.108 clang-1500.0.40.1)
Target: arm64-apple-macosx13.0

The options for compiling the toolchain are as follows.

utils/build-script --skip-build-benchmarks --skip-watchos --skip-tvos --swift-darwin-supported-arch=arm64 --sccache --release-debuginfo --swift-disable-dead-stripping --install-destdir=/Users/kei/111/swift/utils/swift-nightly-install --install-llvm --install-swift --install-lldb --install-llbuild --install-swiftpm --install-swift-driver --install-swiftsyntax --install-playgroundsupport --install-sourcekit-lsp --install-swiftformat --install-swiftdocc --build-swift-static-sdk-overlay --darwin-toolchain-display-name=CodeLabyrinth --darwin-toolchain-display-name-short=CodeLabyrinth --darwin-toolchain-name=CodeLabyrinth --darwin-toolchain-version=1.0 --darwin-toolchain-alias=Local --darwin-toolchain-bundle-identifier=CodeLabyrinth --darwin-toolchain-require-use-os-runtime=0 --install-prefix=/Library/Developer/Toolchains/CodeLabyrinth.xctoolchain/usr --install-symroot=/Users/kei/111/swift/utils/swift-nightly-symroot --darwin-install-extract-symbols ‘--swift-install-components=autolink-driver;back-deployment;compiler;clang-resource-dir-symlink;libexec;stdlib;sdk-overlay;static-mirror-lib;toolchain-tools;license;sourcekit-xpc-service;swift-remote-mirror;swift-remote-mirror-headers’ ‘--llvm-install-components=llvm-ar;llvm-cov;llvm-profdata;IndexStore;clang;clang-resource-headers;compiler-rt;clangd;dsymutil;LTO;clang-features-file’ --swift-primary-variant-sdk=IOS --installable-package=/Users/kei/111/swift/utils/CodeLabyrinth.tar.gz --symbols-package=/Users/kei/111/swift/utils/CodeLabyrinth-symbols.tar.gz --build-subdir=buildbot_osx  --ios --tvos --watchos --swift-stdlib-build-type=Release ‘--llvm-targets-to-build=X86;ARM;AArch64’ --swift-darwin-supported-arch “$(uname -m)”

Am I missing something?

Maybe you can try utils/build-toolchain script.

[FengDeng]

if you use build-script , add "Apple" in version string.

Maybe you can try utils/build-toolchain script.

@WindowsMEMZ Do you happen to know which command in build-toolchain is responsible? We use custom build-script based buildsystem and encountered the exact same issue

grepping through Swift sourcecode doesn't seem to show where that error comes from or the regex used for the version detection

[Naville]

complier-vendor=apple is the reason

build-toolchain actually calls the build-script inside. You can open this script by text editor to see how it works.
