The reader knows how to create an app that solves real-world problems. He/she can develop the initial idea on paper and then try to create the UI in the storyboard. This version is called the early prototype. The reader can experiment with different screen sizes and make the UI work on different screens. We've practiced a nice way to add interactivity and link together different screens. Transition and passing information between screens is a technique that is used in all apps and we have discussed this in detail. We have used the standard iOS toolkit and sample data. The data used here simulates how our app will behave once real data is loaded.
The next chapter discusses modern software development using open source projects. It will show how easy it is to link together several projects using CocoaPods, one of the most popular dependency managers for Swift and Objective...
