To do so, add a new Swift File to your project (see Figure 1).įigure 1. ![]() ![]() Rather than continue writing in Objective-C, you want to harness the new features in Swift and code your new features in Swift.

In this article, I run through a couple of simple examples to illustrate first how you can use Swift within an Objective-C project, and then how to include Objective-C within a Swift project. Rather than force Swift down the developer’s throat, Apple has made it easy to allow Objective-C to interoperate with Swift. Despite Apple’s intention to replace the Objective-C language using Swift, it is not practical in the short term simply due to the fact that developers are deeply entrenched in Objective-C. ![]() As an addendum to our previous article about the role of Swift in iOS app development, we now take a look at how Swift and Objective-C can be used together in iOS apps. ![]()
