The only complaint about swift programming is: they keep changing the programming interfaces, so if I import a third-party code file written with earlier versions of Swift, I have to go through the errors of 'obsolete APIs', updating the function signatures. The changes are automated by Xcode, but it is still a hassle. I am totally OK with introducing new features of Swift language. But changing the API function signatures (even multiple times) seems totally unnecessary, and reflects the API designers' obsession of naming conventions.
