.target(
    name: "YourLibrary",
    dependencies: [
        .product(name: "LoggingPlayground", package: "swift-log-playground")
    ]
),import Logging
import LoggingPlayground
let logger = Logger(label: "main")
LoggingSystem.bootstrap(PlaygroundHandler.init)
logger.debug("The program started.")import Logging
import LoggingPlayground
import SwiftUI
let logger = Logger(label: "main")
@main
struct MyApp: App {
    init() {
        LoggingSystem.bootstrap(PlaygroundHandler.init)
    }
    
    var body: some Scene {
        WindowGroup {
