SwiftUI HStack within a scroll view not showing images correctly

Question

I have the following:

It shows just 1 image if 1 is available or if more than one image is there, it creates a HStack which should be scrollable to show all images:

 ScrollView {
        VStack (alignment: .leading) {
            if userData.profileURL1 != nil {
                ScrollView(.horizontal, showsIndicators: false) {
                    HStack {
                        URLImage(URL(string: userData.profileURL)!, placeholder: Image(systemName: "circle"),
                         content:  {
                            $0.image
                                .resizable()
                                .aspectRatio(contentMode: .fill)
                                .frame(width: (UIScreen.main.bounds.width - 33),height: 500)
                            }
                        )
                        .cornerRadius(12)
                        .padding([.leading,.trailing])
                        URLImage(URL(string: userData.profileURL1!)!, placeholder: Image(systemName: "circle"),
                         content:  {
                            $0.image
                                .resizable()
                                .aspectRatio(contentMode: .fill)
                                .frame(width: (UIScreen.main.bounds.width - 33),height: 500)
                            }
                        )
                        .cornerRadius(12)
                        .padding([.leading,.trailing])
                        if userData.profileURL2 != nil {
                            URLImage(URL(string: userData.profileURL2!)!, placeholder: Image(systemName: "circle"),
                             content:  {
                                $0.image
                                    .resizable()
                                    .aspectRatio(contentMode: .fill)
                                    .frame(width: (UIScreen.main.bounds.width - 33),height: 500)
                                }
                            )
                            .cornerRadius(12)
                            .padding([.leading,.trailing])
                        }
                    }
                }
            } else {
                URLImage(URL(string: userData.profileURL)!, placeholder: Image(systemName: "circle"),
                 content:  {
                    $0.image
                        .resizable()
                        .aspectRatio(contentMode: .fill)
                        .frame(width: (UIScreen.main.bounds.width - 33),height: 500)
                    }
                )
                .cornerRadius(12)
                .padding([.leading,.trailing])
            }
       }
}

The logic works and it displays multiple images if more than one are there, but doesn't show them correctly, the height of the images is not being applied from what I can tell:

The images are scrolling to show the other but the height is all messed up. But when only 1 image is present (else) then the image shows fine, full height and everything.

try setting frame to your placeholders inside HStack.

ScrollView does not know height of content, you have to specify it explicitly. By your code it looks like it should be

ScrollView(.horizontal, showsIndicators: false) {
    HStack {
        URLImage(URL(string: userData.profileURL)!, placeholder: Image(systemName: "circle"),
         content:  {
            $0.image
                .resizable()
                .aspectRatio(contentMode: .fill)
                .frame(width: (UIScreen.main.bounds.width - 33), height: 500)
            }
        )

      // .. other content here

    }
    .frame(height: 500)     // << here !!
