SwiftUI Previews (in Xcode) Breaking After LiveKit Integration in Swift Package

Open jpmcglone opened this issue 2 years ago • 0 comments

Describe the bug When I add LiveKit to my Swift Package Module, it results in SwiftUI Previews breaking for that specific Swift Package. No changes to the package content seem to affect this issue; it solely arises when LiveKit is integrated, and is fixed when LiveKit is removed. I've prepared a minimal project below that effectively demonstrates this bug in action.

SDK Version 1.0.13

iOS/macOS Version Xcode (so, simulator) issue

Steps to Reproduce

  1. Add "LiveKit" dependency to the AppModule Package.swift
  2. Try to preview AppModuleApp.swift

**Note: ** Switch the scheme (target) to AppModule

Expected: it previews like when LiveKit isn't added Actual: it crashes the Preview in Xcode (no import needed)

Screenshots This is AppModuleApp.swift

** Please let me know if you need more information. I cannot figure out why this is breaking, but it's pretty bad since it greatly reduces dev productivity if we can't use Previews**

** Attached is a test project. Open AppModule/Package.swift and disable LiveKit. You'll be able to run Previews. Then, re-enable LiveKit, and Previews won't work. NO imports needed. **
