This should work. struct ContentView: View {     @State var testvar:Double = 66.78     var body: some View {         Text("\(testvar)") } }

I don't think there is a way to adjust lighting but here is how to make a counter @State var counter: Int = 0     var body: some View {         VStack {             Text("\(counter)")             Button("Count Up") {                 counter += 1             }                          Button("Count Down") {                 counter -= 1             }                   }      

there is a way to adjust the device brightness by pressing a button but that will not work like you want it to.

when I click on this link https://developer.apple.com/app-clips/resources/ on click on app clip generator it takes me to downloads page but there is no software.

I tried that I probably need the paid developer account.

try 100 days of swiftUI on hacking with swift.

Thanks.

here is the error message there is only one. Initializer 'init(value:total:)' requires that 'BindingInt' conform to 'BinaryFloatingPoint'

there is a error that keeps popping up on line 17.

Go to /file/new/file/ then select swiftUI view or if you want to load a new scene when pressing a button use a navigation link.

I want to add Scene Storage to the Text and a different variable here is some code I tried that did not work. import SwiftUI struct ContentView: View {     @SceneStorage("TextField") var textfield = ""   @State var Text = ""     var body: some View {                 TextField("Placeholder", text: $textfield,                   $Text)     } } struct ContentView_Previews: PreviewProvider {     static var previews: some View {         ContentView()     } }

Thanks.

There is a reason I want two variables in a textfield but just forget it.

I want to type something up and make appear somewhere else but I also want it to be saved with SceneStorage too. I'm a Beginner coder I need help.

I trying to figure out how to two variables to a textfield and telling a other guy what textfield I meant by.
