Simple SwiftUI TabView with two tabs, with a simple Picker view used on each tab. When the app starts, the Picker is visible and updates the variable. Select the second tab, and the Picker vanishes.
let names = ["Fred", "Wilma", "Betty", "Barney"]
struct WordPickerView: View {
@State var kind: Int = 0
var body: some View {
VStack {
Text(names[kind])
Picker(selection: $kind, label: EmptyView()) {
ForEach(0 ..< names.count) {index in
Text(names[index]).tag(index)
}
}.pickerStyle(SegmentedPickerStyle())
}
}
}
struct ContentView: View {
@State private var selection = 0
var body: some View {
TabView(selection: $selection){
WordPickerView()
.font(.title)
.tabItem {
VStack {
Image("first")
Text("First")
}
}
.tag(0)
WordPickerView()
.font(.title)
.tabItem {
VStack {
Image("second")
Text("Second")
}
}
.tag(1)
}
}
}
In such cases (when you have absolutely equal views) it is better to make them unique with .id
.
So your case is fixed, say, with the following
Picker(selection: $kind, label: EmptyView()) {
ForEach(0 ..< names.count) {index in
Text(names[index]).tag(index)
}
}
.pickerStyle(SegmentedPickerStyle())
.id(UUID().uuidString)
