ios – SwiftUI: ViewModifier callback when view is totally eliminated, like onDisappear however known as solely as soon as

the onAppear onDisappear modifiers might be known as a number of instances whereas the view is a part of the hierarchy.

I do know that there’s a trick to make an onLoad ViewModifier like so

extension View {
    func onLoad(carry out motion: (() -> Void)? = nil) -> some View {
        self.modifier(ViewDidLoadModifier(motion: motion))
    }
}

struct ViewDidLoadModifier: ViewModifier {
    @State non-public var viewDidLoad = false
    let motion: (() -> Void)?

    func physique(content material: Content material) -> some View {
        content material
            .onAppear {
                if viewDidLoad == false {
                    viewDidLoad = true
                    motion?()
                }
            }
    }
}

From the above code, onLoad will solely be known as as soon as

struct MyView: View {
    var physique: some View {
        Textual content("Hey View")
            .onAppear {
                // might print a number of instances
                print("onAppear")
            }
            .onLoad {
               // solely prints as soon as
               // when the view first seems within the hierarchy
               print("onLoad")
            }
    }
}

Is there a technique to have an onUnLoad ViewModifier?

struct MyView: View {
    var physique: some View {
        Textual content("Hey View")
            .onDisappear {
                // might print a number of instances
                print("onDisappear")
            }
            .onUnLoad {
               // solely prints as soon as,
               // when the view is totally eliminated
               print("onUnLoad")
            }
    }
}
