OnAppear calls unexpectedly when Keyboard Appears in SwiftUI

Question

I am experiencing very odd behavior in SwiftUI 2.0 and iOS14.

When the keyboard appears on the screen, the OnAppear method of other tab\'s view called automatically.

Answer 1

Having the same issue myself, I think this is a bug or something like that, however I came up with a solution maybe a workaround until apple will fix it.

The thing that I did is basically I used a LazyVStack, and this seems to be working perfectly.

LazyVStack {
    VStack{
        Text(screenName)
            .font(.title)
        
        TextField("Buggy Keyboard Issue", text: $text)
            .textFieldStyle(RoundedBorderTextFieldStyle())
            
        Text("Issue : When keyboard appears, onAppear of other 2 tabs call automatically.")
            .font(.footnote)
    }
    .padding()
    .onAppear(perform: {
        debugPrint("OnAppear of : \(screenName)")
})
}

Now the OnAppear method of other tab's view it is not called automatically when the keyboard appear.

To avoid reloading your view try with on the TabView

.ignoresSafeArea(.keyboard, edges: .bottom)

It only works on iOS 14
