Ch. 6.6 Loading Paged JSON while Scrolling in SwiftUI (2024)

Learn to use SwiftUI to load pages of JSON as we scroll through a list. When we've seen all the data we've downloaded, we'll download and parse our next page of JSON using URLSession. We'll learn important issues related to Lists, onAppear, and when decoding JSON that may return null instead of an expected value. We'll also learn to use the Task command in SwiftUI, and we'll learn to recognize, diagnose, and correct JSON errors that may trip up new SwiftUI coders. By the time we're done, we will be able to "Catch 'em All" - all available Pokemon creatures. Part of a university course by Prof. John Gallaugher designed for the absolute beginner, where students will learn to program using Swift + SwiftUI. The course will move from no assumed prior programming experience while students learn fundamental, then intermediate and advanced concepts, culminating in a full stack app. Full free course playlist at: https://bit.ly/prof-g-swiftui
