Earlier quoted context omitted.
I use Swift for small applications, but the language is clearly incomplete, and and its tools are not ready for large, complex projects. You can use it, but it's painful. Just today, I had to write dozens of lines of RawOptionSetType code to mimic a C bitmask.
I've been developing for iOS since 2008, so much this! Swift is just not ready, I constantly run into "WTF" moments when I find something that's standard in most languages "has not been implemented yet" in Swift.
No examples? Swift is already much richer than Objective C.
