Debug configuration for Swift/SwiftUI

Is there an example config for running/debugging Swift/SwiftUI? I'm trying various examples from searching but the configurations I created are greyed out so I'm guessing I'm missing a property. I believe this is an iOS app. I also have a macOS app I want to try an edit/run with Fleet. Thanks!

Here's an example of what I'm trying:

{
   "configurations": [
      {
          "type": "xcode-app",
          "name": "Run SwiftUI tutorial",
          "buildTarget": {
              "project": "Fleet SwiftUI Tutorial",
              "target": "Fleet SwiftUI Tutorial",
          },
          "configuration": "iPhone 13 Pro Max",
      },
      
   ]
}
