[swift-users] Segmentation fault: 11 after updating codebase to Swift 3.0

[Rien]

I had a similar problem with Xcode 7.2.
The work around I found then was to remove all source files from the project in the “target membership” except for the main.swift file.
Then compile again, which will (of course) fail with normal errors.
Then I added the files back in, presto, no more segmentation fault.

Maybe worth a try?

Regards,
Rien.
