Quoting from Apple's developer forums:

1. Delete derived Data (Window/Organizer)
2. Clean (Cmd+Shift+K)
3. Re-run on device, after all the indexing and such was finished (dispayed at the top of xcode)

It seems like there have been a few errors similar to this floating around since the new beta was released. Although the error messages aren't exactly the same, they seem to have the same answer. I've personally run into this with a 3rd error related to ranges, and this was the solution in that case as well.
