Installation

You can add LogBird to your project using CocoaPods or Swift Package Manager.

CocoaPods

Add the following line to your Podfile:

pod 'LogBird'

Swift Package Manager

Add the following to your Package.swift file:

dependencies: [
    .package(url: "https://github.com/javiermanzo/LogBird.git")
]

Usage

Log Levels

LogBird supports the following log levels via the LBLogLevel enum:

• .debug: For debugging information.
• .info: For informational messages.
• .warning: For warnings.
• .error: For error messages.
• .critical: For critical issues.

Static Logging

Use the static methods provided by LogBird for simple logging:

LogBird.log(message: "This is an info log")

Instance Logging

Create a custom instance of LogBird for more flexibility:

let customLogger = LogBird(subsystem: "com.example.myapp", category: "Network")
customLogger.log(message: "This is a debug log from the Network category")

Log Parameters

The log method supports additional parameters for more detailed logs.

Logging with extra messages:

let extraMessages: [LBExtraMessage] = [
    LBExtraMessage(title: "Title extra", message: "Message extra")
]
LogBird.log("My Log",
    extraMessages: extraMessages)

Logging with additional info:

LogBird.log("Purchase",
    additionalInfo: ["userId": 12, "planId": 2],
    level: .info)

Logging an error:

let someError = NSError(
    domain: "com.myapp.error",
    code: 500,
    userInfo: [NSLocalizedDescriptionKey: "Error description"]
)

LogBird.log("Log Error",
    error: someError,
    level: .error)

Combine Support

Access logs using Combine to react to new logs in real time:

import Combine

var logs: [LBLog] = []
var subscribers = Set<AnyCancellable>()
let logBird = LogBird(subsystem: "com.example.myapp", category: "UI")

LogBird.logsPublisher
    .receive(on: DispatchQueue.main)
    .sink { [weak self] newLogs in
        self?.logs = newLogs
    }
    .store(in: &subscribers)

SwiftUI View

Use LBLogsView to visualize logs in your app. You can optionally provide a custom LogBird instance; by default, it uses the static instance:

import SwiftUI

struct ContentView: View {
    var body: some View {
        LBLogsView(logBird: LogBird(subsystem: "com.example.myapp", category: "UI"))
    }
}
