This is a bug in iOS 18（Both iPad and iPhone). Unable to find a suitable solution, I ended up rewriting all views using SwiftUI’s highPriorityGesture with UIKit. This bug is truly disappointing.

Request permission for each target：request form I received approval emails about 3 weeks later. A website doesn’t seem to be mandatory; no one visited the URL I provided.

Find a solution for iOS 17+. Reduce Data Struct into a one-dimensional Array. /** ✅ Make sure LazyVStack is always visible. */ ScrollView { LazyVStack { ForEach(data) { item in switch item.viewStyle { // dynamic config view by data case 1: DynamicHeightView1() case 2: DynamicHeightView2() default: DynamicHeightView() } } } } /** ❌ The contents inside a LazyVStack may disappear from view when the user is scrolling or when the keyboard changes the focus state. */ ScrollView { ForEach(data) { section in LazyVStack { ForEach(section) { row in DynamicHeightView() } } } } // ❌ or ScrollView { View() LazyVStack { ForEach(section) { row in DynamicHeightView() } } LazyVStack { ForEach(section) { row in DynamicHeightView() } } View() }

I have a familiar issue and no workaround. :-( Scenario: iOS17 + LazyVStack + ScrollView, ScrollView flitters, and Views inside LazyVStack disappear when TextField changes FocusState.

Same issue and my solution. Scene: iOS17 + ScrollView + LazyVStack + Textfields.(iOS16 working as expected) Log: -[RTIInputSystemClient remoteTextInputSessionWithID:performInputOperation:] perform input operation requires a valid sessionID. Solution: Replace LazyVStack with VStack solved my problem.
