Our iOS research team presented benefits of using Swift to develop iOS applications.
Background: Swift is a powerful and intuitive programming language for iOS, OS X, and watchOS. Writing Swift code is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast. Swift is ready for your next project — or addition into your current app — because Swift code works side-by-side with Objective-C. Copied from http://developer.apple.com/swift/
In this presentation, Roshan from iOS team also explains the key differences between objective C and Swift. These slides may be too technical for you. However, if you are looking to build an app – do not forget to ask us about swift and its advantage.
