How to make ZStack content fully scrollable in a SwiftUI ScrollView
This post discusses how to make stacked content in a ZStack scrollable within a ScrollView. It also covers an issue where applying offsets to ZStack elements interferes with smooth scrolling.
Two solutions are presented:
- Using Paddings: Replace offsets with top paddings on each ZStack element. This increases the element size, allowing ScrollView to calculate the correct content size.
- Using Frames: Maintain offsets but manually set the ScrollView's frame to the sum of all element offsets and a single element's height.
Both methods ensure smooth scrolling through all ZStack content.
