In SwiftUI how can I assign variable in view?

Question

I have this code here (placed in a view):

if videoPos > 0.05 {
                    Text("It Worked Yay!")
                    playerPaused = false
                }

However, since "Type '()' cannot conform to 'View'" I am not sure how I can change the variable when videoPos is > 0.05.

This is videoPos: @Binding private(set) var videoPos: Double

How can I overcome this?

I have pasted where I directly declare and set videoPos equal to another value, here: pastebin.com/9zVr6geB but it isn't inside of the same struct (VideoPlayerControlsView) but in another class, how can I edit it from there? — Aiyush

You can use this }// Your view end .onChange(of: videoPos) { value in playerPaused = false } — Raja Kishan

You can use onChange

}// End HStack
.onChange(of: videoPos, perform: { value in
    if value > 0.05 {
        playerPaused = false
    }
})

if iOS 13 supported then use combine

}// End HStack
.onReceive(Just(videoPos), perform: { value in
    if value > 0.05 {
        playerPaused = false
    }
})

import Combine
