Xcode-Beta (6D520o): Crash In Swift Debugger When Using Static Libraries

Originator:wetzeal
Number:rdar://19792487 Date Originated:10-Feb-2015 10:30 PM
Status:Closed Resolved:23-Feb-2015
Product:Developer Tools Product Version:Xcode-Beta (6D520o)
Classification:Crash/Hang/Data Loss Reproducible:Always
 
Summary:
The attached project causes Xcode to crash when printing a value in the debugger. The trigger appears to be linking against a library, in this case Crashlytics/Fabric. This library provides a modulemap for compatibility with Swift, which could be a factor.

Steps to Reproduce:
1. Open included xcode project
2. Set a breakpoint in application(:didFinishLaunchingWithOptions:)
3. `po self`when the debugger pauses

Expected Results:
A description of `self` is printed to the console

Actual Results:
Xcode crashes completely

Regression:
This did not happen in Xcode 6.1.1

Notes:
In this example project, the crash only occurs when the deployment target is a version of iOS 8. However, the project I originally encountered this issue with targets 7.1. I am not sure what difference causes that project to crash but not this one when targeting iOS 7.
