Dev Log #4
To track books, users need to be able to add them from somewhere. I created a search feature which uses Google Book's API (but I might switch to Amazon soon!) but it only returns 10-40 results at a time. During the weekend, I finally buckled down and created a lazy loading/infinite scroll.
SwiftUI's List or ScrollView is notorious for its bugs. So I wasn't feeling confident about tackling the problem. Luckily, this article provided great guidance.
The basic principle is that each List Item will be appear lazily. They all have a .onAppear modifier which checks whether the list item is near the end of the current list. If it is, then we will fetch more items based on a new index.
In conclusion, the problem wasn't very difficult, but I am very proud of implementing this feature. It is one of those minor features that greatly improve the user experience. I love scrolling endlessly too, so I am one very happy (amateur) developer
