How do I structure a networking layer with async/await in Swift?

Structuring a networking layer in Swift using async/await can simplify your code and make it more readable. Below is an example of how you can set up a basic networking layer with async/await for making GET requests.

Example Networking Layer


        import Foundation

        struct NetworkError: Error {
            let message: String
        }

        class NetworkService {
            static let shared = NetworkService()

            private init() {}

            func fetchData(from urlString: String) async throws -> Data {
                guard let url = URL(string: urlString) else {
                    throw NetworkError(message: "Invalid URL")
                }
                
                let (data, response) = try await URLSession.shared.data(from: url)

                guard (response as? HTTPURLResponse)?.statusCode == 200 else {
                    throw NetworkError(message: "Server error")
                }

                return data
            }
        }

        // Usage
        Task {
            do {
                let data = try await NetworkService.shared.fetchData(from: "https://api.example.com/data")
                // Process the data
            } catch {
                print("Error: \(error)")
            }
        }
