Lazy View SwiftUI

I came up with this solution independently while working on a project. After some more Googling, I found others had come across the same bug and solved it. I am using this as an opportunity to try my first CocoaPod and SwiftPackage.

Why Lazy Load a SwiftUI View?

The primary problem is with NavigationLink. The destination view given will be immediately instantiated and loaded--before the user even navigates to the details page. This is a problem for large details pages that you don't want to have immediately loaded with the previous screen.

Example project:

To run the example project, clone the repo, and run pod install from the Example directory first.

Example usage:

struct ContentView: View {
    var body: some View {
        NavigationView {
            NavigationLink(destination: LazyView(Text("My details page"))) {
                Text("Go to details")
            }
        }
    }
}

Installation

CocoaPods

LazyViewSwiftUI is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'LazyViewSwiftUI'

SPM

LazyViewSwiftUI is also available through Swift Package Manager.

Once you have your Swift package set up, adding LazyViewSwiftUI as a dependency is as easy as adding it to the dependencies value of your Package.swift.
