Apple's new Swift programming language is designed to be interoperable with Objective-C, but what can it do that Objective-C can't? Find out in this course, as Simon Allardice explores the capabilities of each language, showing how and when they intersect–and also the places where the languages don't translate well. Discover how to migrate existing Objective-C projects to Swift and work with both languages in the same project. Then learn best practices for using Objective-C libraries and frameworks in new Swift code.

Topics include:

• Exploring the interoperability of Swift and Objective-C
  
• Comparing language syntax
  
• Understanding how each language uses objects and methods
  
• Bridging arrays, dictionaries, and numbers
  
• Dealing with nil return types from Objective-C methods
  
• Working with NSError in Swift
  
• Working with Swift and Objective-C strings
  
• Adding Swift to an existing Objective-C project
  
• Inheriting between languages
