In my last review about iOS7 development, I held concerns about the platform in regards to Apple locking down the platform so much. I still hold those concerns. However, as Apple moves on we may see the platform available to dev on all machines soon as we move closer and closer to a “cloud” IDE in my opinion.
As Application Development in iOS 7 by Kyle Begemen shows, Apple continually evolves the Xcode platform, the Foundation Framework, updating Objective-C, and so on. Recently announced, they have a new language based off of Objective-C called Swift. I believe this shows how Apple is growing up with their tech and moving it forward. There are a lot of interesting changes here.
