SwiftUI Fundamentals | FULL COURSE | Beginner Friendly

Get your start in SwiftUI with SwiftUI Fundamentals. In this 12 hour course we build 4 apps that ramp up in difficulty. The first 3 apps are quite simple, but the 4th and final app grows substantialy in size and challenge. See the timestamps at the bottom of the description for the full curriculum.

The course has been updated for iOS 15 and iOS 16.

App 1 Weather:
We learn the absolute basics of SwiftUI to build the user interface of a weather app. If you have experience with SwiftUI, feel free to skip this one as it’s very beginner friendly.

App 3 – Barcode Scanner:
We learn to use UIViewRepresentable to connect SwiftUI and UIKit in case SwiftUI doesn’t support a type of user interface you want.

App 4 – Appetizers:
This app is a big one where we put it all our learnings together to build a proper SwiftUI app that works with a network call (updated to Async/Await in iOS 15).
