How can playground or any app exec an swift code or show an update live of view that we are make?
I want to know this because i want to build app that help you to build views without coding..so i want the same Features that used on swift playground and xcode that exec swift code and show update live of view.
That's exactly what Preview does, isn't it ?
@Claude31 Did you now How its work? or how to build Similar?
I have never thought about it. But it must be a bit tricky, a.k.a simulator.
There are two ways to do it. By the way, in your Xcode project next to your code, there should be a live preview. If it doesn't show, just click on the button to resume live updates.
Way 1:
import SwiftUI
struct ContentView: View {
var body: some View {
// Place the content of your view here.
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
Way 2:
import SwiftUI
import PlaygroundSupport
struct ContentView: View {
var body: some View {
// Place the content of your view here.
}
}
PlaygroundPage.current.setLiveView(ContentView())
