Airship 17.6.0

What are the versions of any relevant development tools you are using?

Report

What unexpected behavior are you seeing?

Project fails to build for previews when using Airship 17.6.0. Airship 17.5.1 work fine.

What is the expected behavior?

SwiftUI Previews should build successfully with Airship 17.6.0.

What are the steps to reproduce the unexpected behavior?

1. Create a new SwiftUI project in Xcode;
2. Add Airship 17.6.0 using SPM;
3. Open ContentView (which is created by default when creating a new project);
4. Try running the Preview: Error message: 4 duplicate symbols for architecture arm64 Everything works correctly after downgrading to Airship 17.5.1;

Do you have logging for the issue?

Thanks, looking into it

[rlepinski]

I think this might be a swift data build thing? not really sure but having troubles reliably reproducing this. Could you point to branch GH-382 and let me know if it resolves it for you?

[rlepinski]

I just pushed another change with a fix, was able to reproduce finally after wiping derived data.

I tried using GH-382 but now it doesn't build at all:

Clearing DerivedData does not help.

@neriusv i just pushed another change, it was a codegen issue with the new coredata files

[rlepinski]

I believe this is fixed in 17.6.1

[neriusv]

I can confirm this is fixed in 17.6.1. Thanks!
