SwiftUI 2.0 TabView disable swipe to change page

Try something like the following (tested with some stub code). The idea is to block tab view drag gesture when some condition (in you case start editing) happens

@State var isSearching = false

// ... other code

TabView {
    // ... your code here

    Your_View()
       .gesture(isSearching ? DragGesture() : nil)  // blocks TabView gesture !!
}
.tabViewStyle(PageTabViewStyle(indexDisplayMode: .always))
