Invalid Manifest (xCode 15)

I followed the post here to get crypto working in an Kotlin multiplatform app (iOS side) using this plugin.

However, the compilation fails (in xCode) with the error:

> Task :shared:swiftklibKCryptoIosArm64
error: 'swiftbuild': Invalid manifest (compiled with: ["/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc", "-vfsoverlay", "/var/folders/l6/dvt5060j6qlb9_cr_551vdpw0000gn/T/TemporaryDirectory.OySw0O/vfs.yaml", "-L", "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/pm/ManifestAPI", "-lPackageDescription", "-Xlinker", "-rpath", "-Xlinker", "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/pm/ManifestAPI", "-target", "arm64-apple-macosx13.0", "-sdk", "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS17.0.sdk", "-F", "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/Frameworks", "-I", "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/usr/lib", "-L", "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/usr/lib", "-swift-version", "5", "-I", "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/pm/ManifestAPI", "-sdk", "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS17.0.sdk", "-package-description-version", "5.5.0", "/Users/dusiema/projects/ti-mobile/shared/build/swiftklib/KCrypto/iosArm64/swiftBuild/Package.swift", "-Xfrontend", "-disable-implicit-concurrency-module-import", "-Xfrontend", "-disable-implicit-string-processing-module-import", "-o", "/var/folders/l6/dvt5060j6qlb9_cr_551vdpw0000gn/T/TemporaryDirectory.iiJUpf/swiftbuild-manifest"])

Is this supposed to work with xCode 15 as well?
It is actually compiling my KCrypto code. (Gradle builds in Android Studio).
But building the app in xCode runs into this problem.
Any hints are greatly appreciated. I'd love to get crypto running in my multiplatform app.

We were previously using Xcode 14.3.1, after upgrading to Xcode 15.0.0 (also upgraded to macOS 13.6) we now see a similar error.
