Swift: Xcode 16 - Library not loaded: @rpath/libSwiftSyntax.dylib

[weisunOW]

We recently updated our iOS project to build with Xcode 16, swift 5 mode (SWIFT_VERSION = 5). However our Azure CodeQL pipeline started to fail on database creation with Library not loaded: @rpath/libSwiftSyntax.dylib error for both WidgetExtension and IntentsExtension.

We've tried different CodeQL versions: 2.18.0, 2.19.1, 2.19.2, all failed with the same error. The same command worked when we built with Xcode 15.4, unfortunately we cannot fallback to Xcode 15.4 now.

Here is the database create command, please note that .codeql.yml is currently empty.
codeql database create -l swift codeql-database --threads 0 --codescanning-config .codeql.yml --command \"${WORKSPACE_DIR}/Scripts/ci/az-build-for-codeql.sh\"

The --command build script runs xcodebuild command below, the build script itself builds correctly without CodeQL cli.
xcodebuild -workspace App.xcworkspace -scheme Application -derivedDataPath Build/DerivedData -destination "OS=18.0,name=iPhone 16 Pro Max"

Here is the failure part of the build log, sorry we cannot share the full log due to our policy. The log suggests that libSwiftSyntax.dylib cannot be found in the listed paths, however I'm sure that libSwiftSyntax.dylib come as part of Xcode 16 under /Application/Xcode.app/Content/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/host. Please advise if we have missed anything?

@weisunOW thanks for reporting this!
Currently we do not support scanning Swift code when using Xcode16, but we are working on adding support. We are currently investigating this and will post an update when we have something you can test.

Hi @coadaflorin, I tried the new v2.20.0 CodeQL CLI, I'm still seeing the same error.

[coadaflorin]

Hi @weisunOW, we had to accelerate the release of 2.20.0 to get some updates out and that meant we did not get a chance to merge in the changes that add support for Xcode 16 / Swift 6.0. We will add these in the next release which is currently estimated shortly after the new year. Thank you for your patience and feel free to tag me if you have more questions on the topic.

Hi @coadaflorin, We're seeing the same issue on Xcode 16 using 2.20.1.

Hi @coadaflorin @cbieniakTU, we confirmed that the workaround github/codeql-action#2506 (comment) by @jsm174 worked for us.

Hi all! I was able to reproduce this locally and I am working on a solution. In the meantime, the workaround mentioned above is probably the best way to get around this issue.
