@davdroman please support here or just investigate with me if applicable. Thanks in advance,

[okankocyigit]

Any update on this?

[davdroman]

Can't reproduce. Have you made sure to remove SwiftUIIntrospect-Dynamic and SwiftUIIntrospect-Static from Frameworks and Libraries?

Here is the sample project which is not working for me for the following archive.
https://github.com/okankocyigit/okankocyigit-swiftui-based-test-framework/tree/main

There is no problem with Xcode build from ui. It builds succcessfuly.

But when I try to archive for xcframework it fails.

  -scheme "swiftui-based-test-framework" \
  -destination "generic/platform=iOS" \

Thanks for the repro but your project doesn't seem to use SwiftUI Introspect at all.

I've tried the command you mention in my repro and indeed it fails, but not with the same output as you:

xcodebuild archive \
        -scheme "swiftui-introspect-438" \
        -destination "generic/platform=iOS" \
        -archivePath ./build/ios_devices \
        SKIP_INSTALL=NO \

** ARCHIVE FAILED **


The following build commands failed:
	SwiftEmitModule normal arm64 Emitting\ module\ for\ SwiftUIIntrospect (in target 'SwiftUIIntrospect' from project 'swiftui-introspect')

Fixing the issue by adding a public import UIKit to the top of IntrospectionSelector.swift seems to fix the issue and successfully builds. I don't know if that's your issue or not but I'll release this fix anyway since it's a legitimate fix regardless.

[davdroman]

@okankocyigit the supposed fix has just been merged to main. Please point to main and try and see if that fixes your issue. If so I'll tag a proper release.

[okankocyigit]

Yes it fixes the issue thanks for quick response.

[davdroman]

Great news, thanks for confirming. I’ll tag a release tomorrow.

[davdroman]

1.4.0-beta.4 is out now.
