Usage

Basic one-liner:

        Text("Finished requesting \(users.count) users!")
            .skeleton(with: users.isEmpty)
            .onAppear {
                DispatchQueue.main.asyncAfter(deadline: .now() + 5) {
                    self.users = ["John Doe", "Jane Doe", "James Doe", "Judy Doe"]
                }
        }
    }
}

Advanced customization:

import SkeletonUI
import SwiftUI

struct User: Identifiable {
    let id = UUID()
    let name: String
}

struct UsersView: View {
    @State var users = [User]()

    var body: some View {
        SkeletonList(with: users, quantity: 6) { loading, user in
            Text(user?.name)
                .skeleton(with: loading)
                .shape(type: .rectangle)
                .appearance(type: .solid(color: .red, background: .blue))
                .multiline(lines: 3, scales: [1: 0.5])
                .animation(type: .pulse())
        }
        .onAppear {
            DispatchQueue.main.asyncAfter(deadline: .now() + 5) {
                self.users = [User(name: "John Doe"),
                              User(name: "Jane Doe"),
                              User(name: "James Doe"),
                              User(name: "Judy Doe")]
            }
        }
    }
}
