SwiftUI - NavigationLink nested within a button - swift

Question

I'm working on a onboarding screen:
VStack {
if #available(iOS 14.0, *) {
TabView(selection: $currentStep) {
ForEach(0..<OnBoardingSteps.count) { it in
VStack {
Text(OnBoardingSteps[it].title)
Image(OnBoardingSteps[it].image).resizable().frame(width: 200, height: 200)
Text(OnBoardingSteps[it].description)
}.tag(it)
}
}.tabViewStyle(PageTabViewStyle(indexDisplayMode: .never))
} else {
// Fallback on earlier versions
}
HStack {
Spacer()
Spacer()
HStack{
ForEach(0..<OnBoardingSteps.count) { it in
if it == currentStep {
Rectangle()
.frame(width: 10, height: 10)
.cornerRadius(10)
.foregroundColor(.purple)
} else {
Circle()
.frame(width: 10, height: 10)
.foregroundColor(.gray)
}
}
}
Spacer()
Button(action: {
if self.currentStep < OnBoardingSteps.count - 1 {
self.currentStep += 1
} else {
// now when i click 'Done' it should take me to Signup screen
}
}){
HStack {
Text(currentStep < OnBoardingSteps.count - 1 ? "Next" : "Done")
.foregroundColor(.blue)
Image(systemName: currentStep < OnBoardingSteps.count - 1 ? "arrow.right" : "checkmark")
}
}
}
}
In my button I have some logic to change text based on if I'm on the last onBoarding step.
What im trying to achieve is, when im on the last step, when i click 'Done' i should navigate to the Signup screen.
