Ah yes, I now tried it in a project, and that works as expected. Before I tried it in a Playground, which did not work. So issue solved :)

Yes I would put the code in a separate function. You can call this function during .onAppear on one of your views. You could then also keep it as an action for your button, so clicking the button would also execute the code block.

Where and how are you getting your images? Are you loading the images in the OnAppear of your gridcells?

Not really sure what your scenario is, so there might be a simpler way. However, I had a somewhat similar situation, but this was without a ScrollView. I found something on Hacking With Swift forum that got me to a solution (bit of a hack) Create a State variable that stores the CGSize of your content Put an overlay on your content view that has a GeometryReader with a Color.Clear view (this is the tacky part) In the onAppear of your Color.Clear, set the CGSize State to your GeometryProxy's size Use a basic .frame modifier to set the size of your Scrollview to the size of the State CGSize struct ContentView: View {     @State private var contentSize: CGSize = .zero     var body: some View {         ScrollView {             Rectangle()                 .fill(Color.blue)                 .frame(width: 100, height: 100)                 .overlay(                     GeometryReader { geo in                         Color.clear.onAppear {                             contentSize = geo.size                         }                     }                 )         }         .background(Color.red)         .frame(maxWidth: contentSize.width, maxHeight: contentSize.height)     } }

Put a .navigationTitle() modifier with the title of the file on the VStack inside of the NavigationView in your ts view. NavigationView {     VStack { // Your text views     }.navigationTitle(name) }

You can create your own custom AnnotationViews using the MapAnnotation. See below an example that creates a callout with an image. Map(coordinateRegion: $coordinateRegion, annotationItems: annotations) { annotation in    MapAnnotation(coordinate: annotation.coordinate, anchorPoint: CGPoint(x: 0.5, y: 1)) {        AssetAnnotationView(image: annotation.image)    } } Where AssetAnnotationView could look like this: struct AssetAnnotationView: View {     var image: UIImage     var body: some View {         Image(uiImage: image)             .resizable()             .aspectRatio(contentMode: .fill)             .frame(width: 100, height: 100)             .cornerRadius(3.0)             .padding(4)             .callOut()         }     } } callout is a custom modifier here that draws the callout shape (a rounded rect with a beak/point to the bottom of the view)
