How do I display skeleton loading states in Combine with Swift?

In this article, we will explore how to implement skeleton loading states in a Swift application using Combine framework. Skeleton loading states are a great way to enhance user experience by providing a visual cue that content is being loaded, rather than showing a simple spinner or empty state.

Example of Skeleton Loading States in Swift with Combine

// Import necessary frameworks import SwiftUI import Combine struct ContentView: View { @State private var isLoading: Bool = true @State private var cancellable: AnyCancellable? var body: some View { VStack { if isLoading { SkeletonView() } else { LoadedView() } } .onAppear { // Simulate data loading cancellable = Just(true) .delay(for: .seconds(2), scheduler: RunLoop.main) .sink { _ in self.isLoading = false } } } } struct SkeletonView: View { var body: some View { RoundedRectangle(cornerRadius: 8) .fill(Color.gray.opacity(0.3)) .frame(height: 200) .shimmer() // Additional modifier for shimmer effect } } struct LoadedView: View { var body: some View { Text("Data Loaded Successfully!") .font(.largeTitle) } }
