Heads up... You've reached locked video content where the transcript will be shown as obfuscated text.

So far you’ve been working with views that don’t really do anything. They aren’t interactive. They don’t affect anything else and nothing affects them. Let’s try out something a little more complicated. Like, using a color picker to update the color of an image.

ColorPicker(/*@START_MENU_TOKEN@*/"Title"/*@END_MENU_TOKEN@*/, selection: /*@START_MENU_TOKEN@*/.constant(.red)/*@END_MENU_TOKEN@*/)
ColorPicker("Swifty Color", ...
struct ContentView: View {
  var swiftyColor: Color = .red
struct ContentView: View {
  @State var swiftyColor: Color = .red
selection: swiftyColor
$swiftyColor
.background(swiftyColor)
@State var swiftyOpacity: Double = 0.7
Slider(value: $swiftyOpacity, in: 0...1)
.accentColor(swiftyColor)
.opacity(swiftyOpacity)
@State var swiftyOpacity: Double = 0.7
@State var swiftyColor: Color = .red
@Binding var swiftyOpacity: Double
@Binding var swiftyColor: Color
@State 🟢private var swiftyOp
@State 🟢private var swiftyCo
SwiftyControls(
  swiftyOpacity: $swiftyOpacity,
  swiftyColor: $swiftyColor
)
