Adjust the intensity/brightness of colors in SwiftUI views

SwiftUI makes it incredibly easy to tweak colors with the brightness(_:) modifier. You can lighten or darken any color dynamically by passing a Double value:

0 retains the original color.
1 makes the color fully white.
Negative values darken the color toward black.
Here are two examples:

Lighten Colors

ForEach(0..<8) { num in
Color.blue
.brightness(Double(num) * 0.1)
}

This creates a gradient where blue transitions to almost white.

Darken Colors

ForEach(0..<8) { num in
    Color.blue
        .brightness(Double(num) * -0.1)
}

---

This generates a gradient where blue transitions to almost black.
