[SwiftUI] ForEach문

Identifiable 프로토콜을 따르거나 id parameter 알아서 지정해줘야한다.

private struct NamedFont: Identifiable {
    let name: String
    let font: Font
    var id: String { name }
}


private let namedFonts: [NamedFont] = [
    NamedFont(name: "Large Title", font: .largeTitle),
    NamedFont(name: "Title", font: .title),
    NamedFont(name: "Headline", font: .headline),
    NamedFont(name: "Body", font: .body),
    NamedFont(name: "Caption", font: .caption)
]


var body: some View {
    ForEach(namedFonts) { namedFont in
        Text(namedFont.name)
            .font(namedFont.font)
    }
}
