Using UUIDGenerator causes Linker Error (‘CoreAudioTypes' not found)

[nayooti]

Description

Not sure if this belongs here or is a TCA issue.

Im getting a Linker-Error framework (‘CoreAudioTypes' not found) when importing a framework that uses UUIDGenerator via:

@Dependency(\.uuid) var uuid

Here is a barebones demo project to demonstrate this issue:
https://github.com/nayooti/TCADemo/blob/main/DemoFramework/DemoFramework/DemoView.swift

Summery:

• DemoApp uses DemoFramework
• DemoFeature does compile
• DemoFramework is a TCA module with a DemoFeature: Reducer
• DemoFeature uses @Dependency(\.uuid) var uuid
• When building DemoApp I get this error:

Link DemoFramework (arm64):
  ld: warning: Could not find or use auto-linked framework 'CoreAudioTypes': framework 'CoreAudioTypes' not found
  ld: Undefined symbols:
  Dependencies.Dependency.wrappedValue.getter : A, referenced from:
  DemoFramework.DemoFeature.uuid.getter : Dependencies.UUIDGenerator in DemoView.o

Observations:

• Obviously I am not using CoreAudioTypes anywhere in the project
• When commenting out @Dependency(\.uuid) var uuid DemoApp builds without any errors
• Also happens to any other framework that uses DemoFramework

Checklist

• I have determined whether this bug is also reproducible in a vanilla SwiftUI project.
• If possible, I've reproduced the issue using the main branch of this package.
• This issue hasn't been addressed in an existing GitHub issue or discussion.

Hi @nayooti, the project you provided does not have all of the files necessary to compile. It looks like it is missing two projects:

Can you double check that everything is pushed?

Also, I'm quite certain this problem has nothing to do with this library or TCA. There is a similar issue mentioned in Apple's forums here. Most likely you have a linking problem somewhere in your project, and the complaint about "CoreAudioTypes" is just a red herring.

Since I don't think this is an issue with the library I am going to convert it to a discussion. Feel free to follow up with more information.

Hi brandon, thanks for the response.
I updated the project.

This is a bug in Xcode 15 / 15.1 and I've encountered it as well. The linking of exported dependencies seems to be broken, so every time a symbol is used from one of TCA's dependencies, it needs to be separately added as a package and explicitly linked.

met same issue here, do you find another work around for this issue? seems this only exist when I mark my package as dynamic, when I using default(static), it works as expected

Ok, thank you.
Looks like I will keep my Xcode14-copy a little longer then.
