Programmatic Navigation Paths
Drive navigation with a navigationDestination path.
Programmatic Navigation Paths is a free SwiftUI Academy lesson on CoddyKit — lesson 4 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the SwiftUI Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Navigating From Code
Sometimes a tap is not enough. After saving a form you may want to jump screens yourself. SwiftUI lets you drive the stack from code. ⚙️
A Path You Control
Give NavigationStack a path binding. This array is the live list of screens currently pushed, and editing it changes navigation instantly.
@State private var path = NavigationPath()
NavigationStack(path: $path) { HomeView() }Push by Appending
Append a value to the path and SwiftUI pushes the matching screen. No tap needed, just change the array.
path.append(book)Routing the Value
A navigationDestination maps each value type in the path to a view, so appended data knows which screen to become.
.navigationDestination(for: Book.self) { book in
DetailView(book: book)
}Pop With Remove
Removing the last element pops a screen, exactly like the back button. You stay in full control of the stack from code.
path.removeLast()Jump Home Instantly
To return all the way to the root, empty the path. Every pushed screen disappears at once, perfect for a Done button. 🏠
path.removeLast(path.count)Deep Linking
Because the path is just data, you can build it from a URL or notification, pushing several screens so users land deep inside the app.
NavigationPath Holds Mixed Types
A NavigationPath can store values of different types together, letting one stack route books, users, and settings without a shared enum.
Or Use a Typed Array
If every screen shares one type, a plain typed array works as the path and reads a little more clearly than NavigationPath.
@State private var path: [Book] = []State Drives the Stack
Navigation becomes state. The visible screens always mirror the path array, so your UI stays predictable and easy to reason about.
Test and Restore
Since the path is plain data, you can save it and restore it, recreating exactly where the user left off when they reopen the app.

Recap: Programmatic Paths
You bind a path to NavigationStack and push or pop screens by editing that array, turning navigation into predictable, testable state. 🎉
