Carthage: Some kind of Xcode 8 playground problem prevents building?

[JessyCatterwaul]

I haven't been able to figure out what this means. Clearing Derived Data didn't work. Nor did removing all playgrounds from the repo.

• carthage version: latest
• xcodebuild -version: 8
• Are you using --no-build?
• Are you using --no-use-binaries?
• Are you using --use-submodules?

I don't know. Is it important to find out?

This looks like a swift bug. If you run the xcodebuild command from the log file, it produces the same error.

I'd recommend filing a radar.

I had this same issue building from the command line, disabling optimizations fixed it for me. Thanks!
