I need to implement a simple switch toggle in SwiftUI, but its setting needs to be written to our server. I implemented it with an @State variable and .onChange(), but I'm not sure if this is the best way. Moreover, I don't know the best way to set the initial value of the state property, which also needs to be fetched from the server.

Any advice?

Oh, also, this needs to work on iOS 14.

Thanks!

You can use the onAppear modifier on your view to make the network call to fetch the initial value. If it's not your initial view you can make the call on application start and store the value temporarily on your device. Either way, you have to have an fallback if network is not available.
