You’ve reached the end of your first SwiftUI app: good job! We’ve covered a lot of ground, but I’ve also tried to go nice and slowly to make sure it all sinks in – we’ve got lots more to cover in future projects, so taking a little extra time now is OK.
In this project you learn about the basic structure of SwiftUI apps, how to build forms and sections, creating navigation views and navigation bar titles, how to store program state with the
@State property wrapper, how to create user interface controls like
Picker, and how to create views in a loop using
ForEach. Even better, you have a real project to show off for your efforts.
Anyone can sit through a tutorial, but it takes actual work to remember what was taught. It’s my job to make sure you take as much from these tutorials as possible, so I’ve prepared a short review to help you check your learning.
One of the best ways to learn is to write your own code as often as possible, so here are three ways you should try extending this app to make sure you fully understand what’s going on:
SPONSORED Would you describe yourself as knowledgeable, but struggling when you have to come up with your own code? Fernando Olivares has a new book containing iOS rules you can immediately apply to your coding habits to see dramatic improvements, while also teaching applied programming fundamentals seen in refactored code from published apps.
