I think the best argument against swift is the plethora of knowledge, tutorials, stackoverflow answers there is for objective-c. When I started learning Unity in 2009, I wanted to use C#. Yet 90 % of all the tutorials, docs, etc.. was in javascript at the time. As I was fairly new to programming then, translating from javascript to C# slowed me down. In hindsight, if I just used javascript I would've progressed much quicker than I did. I think the situation within a year will be different, the iOS community is producing swift tutorials en masse. But I would advice you to start with objective-c.

The best iOS material is: - Objective-C programming book from big nerd ranch or Programming in Objective-C from Stephen G. Kochan (more in-depth) - cs193p from Stanford (iTunesU) iOS 7 course is objective-c. iOS 8 course (starting in 2015) will be swift.

After cs193p you should know enough to make apps. If you want to be a great iOS developer, you should also learn: - ios / cocoa design patterns - cocoapods | git - visit http://nshipster.com - visit http://objc.io - Learn from other apps source code: http://maniacdev.com/2010/06/35-open-source-iphone-app-store...
