Hi,

I having a hard time trying to add a view to a view. I like the user to tap the screen of an iPad and a view show up. If repeted, more views show up on the location the user tapped. I like to build an array that stores the data for the views as they are created.

The data model will include some id, some text, location.

I put everything in a ZStack and onTapGesture and I can add items to the array.

The problem is in displaying the items by go through the array with a ForEach , I can't make it work...

Any tip world be appreciated!

Ps. I have gone through the Hacking with IOS SwiftUI, but I don't have any other experience...

Some code examples showing what you've done would be helpful.

Here is my code that don't work.

import SwiftUI

struct ContentView: View {

@State private var dataArray = [Data]()
@State private var pos = CGPoint(x: 10, y: 10)
@State private var offset = CGFloat(50)

struct Data: Identifiable {
    let id = UUID()
    var text = String("Start text")
    var pos: CGPoint = CGPoint(x: 10, y: 10)
}

var body: some View {
    ZStack {
        GeometryReader { geo in
            if self.dataArray.isEmpty {
                Text("Klick to add a text")
                    .frame(width: geo.size.width, height: geo.size.height)
                    .background(Color.white)
                .onTapGesture(count: 2) {
                print("Tapped")
                self.dataArray.append(Data(text: "New line", pos: CGPoint(x: geo.frame(in: .global).midX, y: geo.frame(in: .global).midY)))
                self.offset += 20
                    print(self.dataArray)}

            } else {
                ForEach(self.dataArray) { data in
                    Text(data.text)
                    .frame(width: geo.size.width, height: geo.size.height)

// .background(Color.red) .position(x: data.pos.x + self.offset, y: data.pos.y) .gesture(DragGesture() .onChanged( { value in

                            self.pos = value.location
                        }))

                }.onTapGesture(count: 2) {
                    print("Tapped")
                    self.dataArray.append(Data(text: "New line", pos: CGPoint(x: geo.frame(in: .global).midX, y: geo.frame(in: .global).midY)))
                    self.offset += 20
                    print(self.dataArray)
            }
        }

    }

    }
}

}
