Xcode always freezes when switching branches

Question

When using Xcode 8's built-in source control, switching between two branches almost always causes Xcode to freeze and requires force quitting the app. My branches aren't particularly worlds apart. Doesn't seem like it's guzzling excessive memory or CPU either. What's the deal?

Answer 1

Turns out this is a known issue in Xcode 8 and 8.1.

It may be that your workspace or project is saved in iCloud. I turned off automatic saving of Desktop folders to iCloud, and moved my workspace from iCloud to my local desktop, and it works fine now.
