Objective-C isn’t deprecated at all. There is more chance of current valid Swift code being deprecated in a year than Objective-C. In fact, all Swift code written in its first two years of public existence is completely deprecated now. The same code, had it been written in Objective-C would be perfectly valid today.

It's not to hard to convert to Swift 3.0. Apple's converter helps a lot. I documented most of the things I had to change.

That's gross oversimplification and misleading. I was recently given the source of a large iOS app belonging to a company that our company purchased. The code is very well written, just has not been maintained past Swift 2. The converter did more hard than it solved. Xcode Swift converter is only good for small projects with no advanced language use.
