Yes, obviously Swift. I am brand new to iOS development, and picked Swift for this exact reason. I figured that if it proved to be a bad choice, I'd find out quickly and learn Objective C. Here are my impressions so far. - The Apple documentation does a good job of covering both languages. - A lot of 3rd party documentation is being maintained to cover Swift, e.g. much of the material on raywenderlich.com. - There are good libraries. Objective C libraries for networking and JSON have Swift versions (alamofire, SwiftyJSON, Starscream). - While it isn't difficult to understand Objective C answers to questions, (e.g. on StackOverflow), there are often Swift answers too. - I haven't found anything that works in Objective C but not Swift, but then I haven't tried anything very advanced either. My app is very simple so far. I think that Swift has some bizarre and ugly features, but it seems much nicer than Objective C. One negative: XCode is not a great IDE for Swift. Refactoring just doesn't work. Renaming things tied to the UI via the storyboard is asking for trouble. I don't know whether this is true for Objective C also. In general XCode is just way, way behind Intellij, the IDE I use for Java.
