Got it fixed in our ObjectiveC-only project by adding empty Swift file. Don't remove it, just keep it there forever!

For anybody not using BUCK but still experiencing this issue, try adding /usr/lib/swift in your target's Runtime Search Paths (under Build Settings). Instantly fixed things up for me.

This worked for me:
- Go to "Window" tab -> "Devices and Simulators"

- Click "Create"
