Hi I need to fix an error "Missing argument for parameter 'scannedCode' in call" on the preview section for my code, any help or advice would be really appreciated!

import SwiftUI

struct PageThree: View {
  var scannedCode: String 
  var body: some View {
    Text("Code: " + scannedCode)
  }
}

struct PageThree_Previews: PreviewProvider {
  static var previews: some View {
    PageThree()
    //error above
  }
}

In the Preview, you need to pass a "scannedCode" to your "PageThree" struct.

Try this:

struct PageThree_Previews: PreviewProvider {
    static var previews: some View {
        PageThree(scannedCode: "some text...")
    }
}
