Hello, Can someone recommend me a good (preferably physical) book for learning iOS (7 or 8)? Are all books for iOS 8 in swift? I want to get started with Objective-C first. I already have programming experience in .NET. I know about the courses from Stanford and the one on stacksocial, but I'm looking for an actual book as I like reading more than watching a video. I'll do the video courses later.
