Introduction to SwiftUI

17:18 - Views are lightweight

struct SandwichDetail: View {
    let sandwich: Sandwich

    var body: some View {
        Image(sandwich.imageName)
            .resizable()
            .aspectRatio(contentMode: .fit)
    }
}

18:30 - Views are composed

struct SandwichDetail: View {
    let sandwich: Sandwich

    var body: some View {
        Image(sandwich.imageName)
            .resizable()
            .aspectRatio(contentMode: .fit)
    }
}

19:52 - View are dynamic

struct SandwichDetail: View {
    let sandwich: Sandwich
    @State private var zoomed = false

    var body: some View {
        Image(sandwich.imageName)
            .resizable()
            .aspectRatio(contentMode: zoomed ? .fill : .fit)
            .onTapGesture { zoomed.toggle() }
    }
}

21:40 - Where is truth?

struct SandwichDetail: View {
    let sandwich: Sandwich
    @State private var zoomed = false

    var body: some View {
        Image(sandwich.imageName)
            .resizable()
            .aspectRatio(contentMode: zoomed ? .fill : .fit)
            .onTapGesture { zoomed.toggle() }
    }
}
