Eliminates some UI elements if inside VStacks

[IZ-Labs]

This is a bit of a weird one an potentially not iPages related. I'm curious if you can recreate this issue.

I was using the default apple PageTabViewStyle but saw this library and gave it a shot. My app has buttons that show up based on if statements. This worked fine with PagesTabView, but upon adding iPages, the buttons inside if statements disappear. If I remove the if statement the buttons pop back up.

Not quite sure what the issue is. I've attached my ContentView.swift file below, with most of my code removed for clarity.

`
import SwiftUI
import HealthKit
import HealthKitUI
import iPages

class SummaryHolder: ObservableObject {
@published var theSummary: HKActivitySummary = HKActivitySummary();
}

struct ContentView: View {
var body: some View {
iPages{
ZStack{
LinearGradient(gradient: Gradient(colors: [.black, Color("darkBlue")]),
startPoint: .topLeading,
endPoint: .bottomTrailing).ignoresSafeArea()
VStack {
VStack {
if movePercent >= 50 {
Button(action: /@START_MENU_TOKEN@//@Placeholder=Action@/{}/@END_MENU_TOKEN@/) {
DispenseButton(title: "One Spin",
textColor: .blue,
backgroundColor: .white)
}
}

                if movePercent >= 75 {
                Button(action: /*@START_MENU_TOKEN@*//*@PLACEHOLDER=Action@*/{}/*@END_MENU_TOKEN@*/) {
                    DispenseButton(title: "Two Spins",
                                   textColor: .blue,
                                   backgroundColor: .white)
                }
                }
                
                if movePercent >= 100 {
                Button(action: /*@START_MENU_TOKEN@*//*@PLACEHOLDER=Action@*/{}/*@END_MENU_TOKEN@*/) {
                    DispenseButton(title: "Three Spins",
                                   textColor: .blue,
                                   backgroundColor: .white)
                }
                }
                
                if movePercent < 50 {
                    Image(systemName: "exclamationmark.triangle.fill") .renderingMode(.original)
                        .resizable()
                        .aspectRatio(contentMode: .fit)
                        .frame(width: 180, height: 180, alignment: /*@START_MENU_TOKEN@*/.center/*@END_MENU_TOKEN@*/)
                    
                    Text("Get moving and try again later").font(.system(size: 20, weight: .bold, design: .default))
                        .foregroundColor(.white)
                        .padding().multilineTextAlignment(.center)
                }
            }
            Spacer()
        }
    }
        Text("Add Bluetooth Menu here").tabItem {
                Image(systemName: (selected == 0 ? "sun.fill" : "sun"))
                Text("Home")
            }
    }.hideDots(false).edgesIgnoringSafeArea(.all)
}

}

struct ContentView_Previews: PreviewProvider {
static var previews: some View {
Group {
ContentView()
}
}
}

Yeah this is a problem with iPages. This code doesn't work:

struct ContentView: View {
    @State var displayButton: Bool = false
    
    var body: some View {
        Toggle("Toggle Button", isOn: $displayButton)
        
        iPages {
            if displayButton {
                Button("Button is Displayed") { }
            } else {
                Button("Button is not displayed") { }
            }
        }
    }
}

Will dig more into this issue

Any news on this matter or alternative library to use?

I think this library is not being worked on right? I am having big problems with TabView and I was looking at this library, but this issue is holding me back. Views inside the iPages control never seem to update.
