This was our biggest project yet, but we’ve covered a huge amount of ground: adding
Comparable to custom types, finding the documents directory, integrating MapKit, using biometric authentication, secure
Data writing, and much more. And of course you have another real app, and hopefully you’re able to complete the challenges below to take it further.
Between this and Instafilter you’ve now seen how to embed any part of UIKit into your app – any
UIViewController can now be placed inside SwiftUI. This massively widens the types of apps you can build, as long as you’re able to spend the time learning some UIKit. Over time SwiftUI will grow and expand what it’s capable of, but right now it’s important to know its limits and play to its strengths!
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.
