Summary:
I haven't been able to use lldb with Swift in Xcode since Swift first came out. In the most recent months, I was under the impression that this was because I was using Carthage, which according to Apple is not supported due to the use of precompiled Swift binaries.

However, I recently started playing with a side project without the use of Carthage, and after writing just a couple hundred lines of Swift on a branch new Xcode 8 GM project, as soon as I tried to set a breakpoint and `po` anything, I only got lldb errors everywhere.

See open source Github project that I used to reproduce this: https://github.com/JaviSoto/SwiftPoker. In case I push more commits, try commit hash `28c3b4acfe4c1bfa80a99f4071f75b00c99762b4` where I definitely reproduced these errors. See attached screenshots for examples of the portions of code where I set the breakpoints and the errors I got.

Steps to Reproduce:
1. Create Xcode 8 Swift project
2. Write some Swift
3. Set breakpoints in Swift code
4. `po variable` in lldb

Expected Results:
Variable contents are printed in the debugger

Actual Results:
Different types of errors appear, `po` never works.

Version:
Xcode 8 GM
Swift 3.0 GM
OS X 10.11.6
