How to blend views together

When placing one view over another, you can control the way they overlap by using the blendMode() modifier. This contains a variety of ways you can mix colors together, such as using their difference or using a color burn – these will be familiar if you’ve used Core Graphics or something like Photoshop before.

To demonstrate this we could create a ZStack with two images inside, where the second has a .multiply blend mode so that it darkens the colors behind it:

ZStack {
    Image("paul-hudson")
    Image("example-image")
        .blendMode(.multiply)
}
