logger.warning("This is a warning message")
logger.error("This is an error message")

Console :

• ⚠️ ExampleTests.swift:36 - defaultLog()> error
• ❌ ExampleTests.swift:36 - defaultLog()> error

Custom Logging Labels

let customLogger = YHLogger(debugLabel: "🩵", 
                            infoLabel: "💚", 
                            warningLabel: "💛", 
                            errorLabel: "💔")

customLogger.debug("Custom debug message")
customLogger.info("Custom info message")
customLogger.warning("Custom warning message")
customLogger.error("Custom error message")

Console:

• 🩵 ExampleTests.swift:47 - customLog()> custom debug
• 💚 ExampleTests.swift:50 - customLog()> custom info
• 💛 ExampleTests.swift:53 - customLog()> custom warning
• 💔 ExampleTests.swift:56 - customLog()> custom error

Logging HTTP Requests and Responses

let logger = YHLogger()

do {
    var request = URLRequest(url: URL(string: "https://dummyjson.com/user/login")!)
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    request.httpMethod = "POST"
    request.httpBody = try JSONEncoder().encode(["username": "test", "password": "1234"])

    let (data, response) = try await URLSession.shared.data(for: request)
    
    logger.request(request, response: response, data: data)
    
} catch {
    logger.error("Failed to encode request parameters or fetch data from the server: \(error.localizedDescription)")
}

Console:

🛜 ExampleTests.swift:74 - requestLog()> POST https://dummyjson.com/user/login
Request Headers: {
  "Content-Type" : "application\/json"
}
Body: {
  "username" : "emilys",
  "password" : "emilyspass"
