Migration provides an opportunity to re-examine existing objective-c applications, as well as the Swift code to better optimize the architecture, logic, and performance of your application. Directly, you will use the previously learned mix and match and the interoperability between the two languages for incremental migration work. The Mix-and-match feature makes it easy to choose which features and functions to use with Swift and which are still imple
