I wouldn't recommend Swift to anyone that's new to the iOS SDK. I answered this question recently on stack overflow (
http://stackoverflow.com/a/25751738/77567). Here's what I said:
- Objective-C will be around and supported for a long time. (Apple has a massive amount of Objective-C source code that it's not going to port to Swift any time soon.)
- Almost all iOS tutorials, examples, and books use Objective-C.
- Almost all iOS-specific third-party source code you might want to use is implemented in Objective-C.
- It's easier to use C and C++ libraries from Objective-C than from Swift.
- There are many Objective-C experts you can get help from. There are very few Swift experts.
- The Swift language and its standard library are currently not very well documented.
Stick with Objective-C for now. When you're comfortable with the iOS SDK and Swift is better documented, you can consider learning Swift.
