Swift version doesn't compile in Xcode 6 final

[altruic]

The Swift version of this class doesn't compile in the final Xcode 6 release. I adjusted the code so that Xcode stopped complaining about errors and warnings in the IDE, but the compile still failed with:

Referring to an argument in another function!
  store float %1, float* %.coerced, !dbg !390
LLVM ERROR: Broken function found, compilation aborted!

This error went away when I commented out bounds and backgroundColor, but I didn't find anything obviously wrong with those methods. Changing the type of backgroundColor to UIColor? (like the base class) didn't resolve the compiler error, either.

Any ideas on what the problem might be? I'm pretty new to Swift errors. Thanks.

This is fixed now.
