Could someone please paste this ContentView.swift in a new SwiftUI project and run it a couple of times to see if you get the “TvAiringTodayView” message 2 times in the console when you click on the “TV” tab the first time? I have isolated it to this setup on my machine and see the following in my console when clicking the “TV” tab in the simulator:initMainViewinitMovieMainViewinitTvMainViewinitTvButtonBarViewinitTvAiringTodayViewinitTvAiringTodayViewIt doesn't seem like the TvAiringTodayView should init twice when clicked, but it does.import SwiftUI
struct ContentView: View {
var body: some View {
TabView {
//Movies View
MovieMainView()
.tabItem {
Image(systemName: "film")
Text("Movies")
}
//TV View
TvMainView()
.tabItem {
Image(systemName: "tv")
Text("TV")
}
}
}
init() {
print("initMainView")
}
}
struct MovieMainView: View {
var body: some View {
VStack {
Text("MovieMainView")
}
}
init() {
print("initMovieMainView")
}
}
struct TvMainView: View {
var body: some View {
VStack {
ScrollView(.vertical, showsIndicators: false) {
TvButtonBarView()
}
}
}
init() {
print("initTvMainView")
}
}
struct TvButtonBarView: View {
@State private var selectedViewType = 0
var viewType = ["On The Air", "Top Rated", "Popular"]
var body: some View {
VStack {
Picker(selection: $selectedViewType, label: Text("Strength")) {
ForEach(0 ..< viewType.count ) {
Text(self.viewType[$0])
}
}.pickerStyle(SegmentedPickerStyle())
if selectedViewType == 0 {
TvAiringTodayView()
}
// if selectedViewType == 1 {
// TvTopRatedView()
// }
// if selectedViewType == 2 {
// TvPopularView()
// }
}
}
init() {
print("initTvButtonBarView")
}
}
struct TvAiringTodayView: View {
var body: some View {
Text("TvAiringTodayView")
}
init() {
print("initTvAiringTodayView")
}
}
