SwiftUILogger

Logging to a SwiftUI View

What is SwiftUILogger?

SwiftUILogger allows you to log events by reference. Then you can display all the events using the LoggerView and passing the logger into the initalizer.

Why use SwiftUILogger?

SwiftUILogger can be used while developing and testing your application to quickly see the debug logs without needing to be attached to LLDB session or Xcode.

Example Usage

import SwiftUI
import SwiftUILogger

let logger = SwiftUILogger(name: "Demo")

@main
struct SwiftUILogger_DemoApp: App {
    @State private var isPresentedLogger: Bool = false

    var body: some Scene {
        WindowGroup {
            NavigationStack {
                ContentView()
                    .sheet(isPresented: $isPresentedLogger) {
                        LoggerView(logger: logger)
                    }
                    .toolbar {
                        Button(
                            action: { isPresentedLogger.toggle() },
                            label: { Image(systemName: "ladybug") }
                        )
                    }
            }
        }
    }
}

// MARK: - ContentView

struct ContentView: View {
    init() {
        logger.log(level: .info, message: "init")
    }

    var body: some View {
        VStack {
            Image(systemName: "globe")
                .imageScale(.large)
                .foregroundColor(.accentColor)
            Text("Hello, world!")
        }
        .padding()
        .onAppear {
            logger.log(level: .info, message: "onAppear")
        }
    }
}
