How to Implement Tab View Navigation in SwiftUI: A Comprehensive Guide

In SwiftUI, you can create a user onboarding layout with horizontal pagination with a few lines of code using the TabView.

Create a simple user onboarding layout using Tab View with the PageTabViewStyle.

Tab View with Page Style  

  • The TabView has a modifier called tabViewStyle that lets you create a horizontal scroll with pagination. 
  • In this layout, we have 3 views. Each of these RoundedRectangle an be replaced by a dedicated view.

TabView {
	RoundedRectangle(cornerRadius: 30).padding()
	RoundedRectangle(cornerRadius: 30).padding()
	RoundedRectangle(cornerRadius: 30).padding()
}
.tabViewStyle(PageTabViewStyle())

..

Show or Hide Dots  

You can set the indexDisplayMode for the PageTabViewStyle to always, automatic or never.

.tabViewStyle(PageTabViewStyle(indexDisplayMode: .always))

..

Final Output:

TabView {
    RoundedRectangle(cornerRadius: 30)
        .fill(Color.blue)
        .padding()
    RoundedRectangle(cornerRadius: 30)
        .fill(Color.red)
        .padding()
    RoundedRectangle(cornerRadius: 30)
        .fill(Color.purple)
        .padding()
}
.tabViewStyle(PageTabViewStyle(indexDisplayMode: .always))
