Here’s a simple circle image using SwiftUI. This is pretty much taken from the SwiftUI Tutorial with a few additions.

struct CircleImage: View {
    var image: Image
    var borderColor: Color = .white
    var shadowRadius: CGFloat = 10

    var body: some View {
        image
            .clipShape(Circle())
            .overlay(Circle().stroke(borderColor, lineWidth: 4))
            .shadow(radius: shadowRadius)
    }
}

In this case we pass and image to the CircleImage, clipping it into a circle shape. Then we display a line (in white by default) around it with a shadow (with radius 10 by default).

We simply clip the supplied image, i.e.

CircleImage(image: Image("imageFrom.Assets.xcassets"), 
   borderColor: .red, 
   shadowRadius: 5)

The image should be stored within the Assets.xcassets editor.
