scrollview

问题 Trying to make a custom list using a view as the list row style (to get rid of the ugly line separates in the list by default).

问题 I want to be able to resize and move an image in SwiftUI (like if it were a map) with pinch to zoom and drag it around. With UIKit I embedded the image into a UIScrollView and it took care of it, but I don't know how to do it in SwiftUI. I tried using MagnificationGesture but I cannot get it to work smoothly.
