I want to start and integrate SwiftUI in an existing project. For starters I've added a SwiftUI file. There's a problem with the preview of this file, it is paused. When I hit the resume button, I see that an error occurs:
remark: Incremental compilation has been disabled: it is not compatible with whole module optimization
Command CompileSwiftSources failed with a nonzero exit code
Above it, there are no hints to what this nonzero exit code could be, or what is causing it.
Does anyone have a pointer for me on how to resolve this? Needless to say that the preview works fine in a new project.
