All About Navigation

In this chapter, we will examine navigation in SwiftUI. We will begin with an introduction to the concept of navigation in iOS in general terms; then, we will examine navigation as a response to user interaction and programmatic navigation. We will cover the changes introduced in SwiftUI 4 (iOS 16), along with an explanation of navigation in previous versions. The most advanced techniques require iOS 16, and they make advanced navigation control easy – so easy and powerful that all the previous patterns for navigation become unnecessary.

We are going to cover these main topics:

• Navigation as a concept in iOS and other platforms
• Showing a tab bar title with NavigationView
• Presenting views with NavigationLink (pre-iOS 16)
• Adding buttons to NavigationView and activating navigation programmatically
• Using navigationDestination with NavigationStack
• NavigationSplitView – multicolumn navigation
• Direct navigation stack manipulation...
