import SwiftUI
struct ContentView: View {
@State private var showiOSDetail = false
var body: some View {
VStack {
Button(action: {
self.showiOSDetail.toggle()
}) {
Text("iOS Blog")
.foregroundColor(Color.white)
}
.padding()
.background(Color.blue)
if showiOSDetail {
Text("You are click on iOsDevCenters ")
.font(.headline)
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
