This repo collects known test cases crashing the Swift compiler. All tests cases in the crashes/ directory are known to generate a compiler crash under Xcode 6.1 beta (Xcode 6 GM seed, "xcode_6.1_beta.dmg").
Help us towards a rock solid Swift compiler by contributing any compiler crashes you may encounter.
Happy Swifting! :-)
