How can I put the Image in the background of a Form in SwiftUI?

Question

I'm currently working on an app and I wonder how to insert an image as a background of a Form in SwiftUI.

I have already tried this:

.onAppear {
   UITableView.appearance().backgroundView = UIImageView(image: UIImage(named: "Background"))  
}

First, it seemed to work, but when I pressed one of the multiple NavigationLinks that has the Form, the App crashes. Thanks!

You need to clear both the UITableView and the UITableViewCell appearance:

UITableView.appearance().backgroundColor = UIColor.clear
UITableViewCell.appearance().backgroundColor = UIColor.clear

Then, you can change the background as you wish:

struct ContentView: View {
    init() {
        UITableView.appearance().backgroundColor = UIColor.clear
        UITableViewCell.appearance().backgroundColor = UIColor.clear
    }

    var body: some View {
        Form {
            Text("Item!")
                .listRowBackground(Color.clear)
        }
        .background(
            Image("Background")
        )
    }
}

(You also need .listRowBackground if you want to change the row background.)
