@Priff That might be a new issue then. If everything in your app was built from source with XCode 15.3, my understanding of the issue this thread is about is that it would all work. If that isn't working, that's a different root cause than ~everyone else was seeing here. @Samuellllll AFAIK, it's the same in cocoapods. If the empty project with no deps isn't working in XCode 15.3, that's new to me (and may be the same issue as @Priff is seeing).

Yes, that's because it's been by-design since XCode 14.3. You need to rebuild all of your upstream dependencies with a version of XCode 14.3 or greater. There is no known easy way to figure out which upstream dependencies must be rebuilt that works for every project; I just know how to do it for projects that use Carthage as posted above.
