How to draw images using Image views

Use the Image view to render images inside your SwiftUI layouts. These can load images from your bundle, from system icons, from a UIImage, and more, but those three will be the most common.

To load an image from your bundle and display it inside an image view, you’d just use this:

var body: some View {
    Image("example-image")
}

Note: I’m not going to repeat the var body: some View { part from now on – you get the idea. In the future I’ll show it only when it really matters.

To load icons from Apple’s San Francisco Symbol set, use the Image(systemName:) initializer, passing in the icon string to load, like this:

Image(systemName: "cloud.heavyrain.fill")

Finally, you can create an image view from an existing UIImage. As this requires more code, you’ll need to use the return keyword explicitly:

guard let img = UIImage(named: "example-image") else {
    fatalError("Unable to load image")
}

return Image(uiImage: img)

If you’re using the system icon set, the image you get back is scalable and colorable, which means you can tint the image using the same foregroundColor() modifier you’ve already seen:

Image(systemName: "cloud.heavyrain.fill")
    .foregroundColor(.red)

And it also means you can ask SwiftUI to scale up the image to match whatever Dynamic Type text style it accompanies, if any:

Image(systemName: "cloud.heavyrain.fill")
    .font(.largeTitle)
