His whole argument is that if Apple had to pick one language today, it would be Objective C because internally they have largely stuck with Objective C up to now. Well, Apple isn't going to pick one language today. They might deprecate Objective C in 5 or 10 years, but in the near term nothing should change. They're infamous for dropping "legacy" so I wouldn't rule out Objective C having a finite lifespan. The author is right that the developer community has really embraced Swift. It is a much nicer language, with a lot less visual noise, for example. As a quick aside, I've been working on a Cookbook for the Swift: http://www.h4labs.com/dev/ios/swift_cookbook.html http://www.h4labs.com/dev/ios/swift_cookbook.html And I've been adding to a Github repo with lots of little examples: https://github.com/melling/ios_topics/blob/master/README.org https://github.com/melling/ios_topics/blob/master/README.org Finally, the Stanford CS193 course has start for Swift and iOS 10: https://itunes.apple.com/us/course/developing-ios-10-apps-swift/id1198467120 https://itunes.apple.com/us/course/developing-ios-10-apps-sw...
