SwiftUI - Not changing views - swift

Question

I have a form that I want to change views from if a Bool is false:
var body: some View {
NavigationView {
Form {
Section {
Toggle(isOn: $ClientAnswer) {
Text("Client answer")
}
if ClientAnswer {
Toggle(isOn: $submission.fieldOne ) {
Text("Field One")
}
Toggle(isOn: $submission.fieldTwo ) {
Text("Field Two")
}
}
}
Section {
Button(action: {
if self.ClientAnswer{
self.placeSubmission()
}
else {
ShowRS() //**change views here.**
print("test")
}
}){
Text("Submit")
}
}.disabled(!submission.isValid)
}
}
}
The code is being executed as print("test") works, but it doesn't change view it just stays on the same view?
The view I am trying to switch to is:
struct ShowRS: View {
var body: some View {
Image("testImage")
}
}

You have to include ShowRS in your view hierarchy -- right now, it's just in your Buttons action callback. There are multiple ways to achieve this, but here's one option:
struct ContentView : View {
#State private var moveToShowRSView = false
var body: some View {
NavigationView {
Button(action: {
if true {
moveToShowRSView = true
}
}) {
Text("Move")
}.overlay(NavigationLink(destination: ShowRS(), isActive: $moveToShowRSView, label: {
EmptyView()
}))
}
}
}
struct ShowRS: View {
var body: some View {
Image("testImage")
}
}
I've simplified this down from your example since I didn't have all of your code with your models, etc, but it demonstrates the concept. In the Button action, you test a boolean (in this case, it'll always return true) and then set the #State variable moveToShowRSView.
If moveToShowRSView is true, there's an overlay on the Button that has a NavigationLink (which is invisible because of the EmptyView) which will only be active if moveToShowRSView is true
