How to blend views together
Fully updated for Xcode 11.3
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)
