What you learned

We’ve had some really long projects recently, but that’s mainly a result of your SwiftUI skills really growing – you’re way past the basics now, so you’re able to tackle bigger projects that solve bigger problems. I realize it can feel tiring working on these larger projects, but I hope you’re able to look back on what you built and feel good – you’ve come such a long way!

While completing these projects, you also learned:

Reading environment values using @EnvironmentObject.
Creating tabs with TabView.
Using Swift’s Result type to send back success or failure.
Manually publishing ObservableObject changes using objectWillChange.send().
Controlling image interpolation.
Adding swipe actions to list rows,.
Placing buttons in a ContextMenu.
Creating local notifications with the UserNotifications framework.
Using third-party code with Swift package dependencies.
Using map() and filter() to create new arrays based on an existing one.
How to create dynamic QR codes.
Attaching custom gestures to a SwiftUI view.
Using UINotificationFeedbackGenerator to make iPhones vibrate.
Disabling user interactivity using allowsHitTesting().
Triggering events repeatedly using Timer.
