FLLogs

FLLogs is a logging utility for Swift that provides a simple and convenient way to log messages during the development and debugging phases of an iOS or macOS app. It allows developers to log messages with different log levels and customize the format and destination of the logs.

Installation

CocoaPods

CocoaPods is the dependency manager for Cocoa Libraries. You can install Cocoapods using the following command:

$ sudo gem install cocoapods

If you wish to integrate FLLogs in your project, then make following changes in your Podfile:

platform :ios, '10.0'
use_frameworks!
target 'YourAppName' do
pod "FLLogs"
end

After saving Podfile. Run the following command:

$ pod install

Install using Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.

Once you have your Swift package set up, adding FLLogs as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/Nickelfox/FLLogs", .branch("master"))
]

Manually

If you don't want to use any dependency manager in your project, you can install this library manually too. Just download and add the Source folder to your project.

Features

Log messages with different log levels: .debug, .info, .warning, .error, and .custom.
Customize log format with date, log level, tag, and message.
Print logs to console or write logs to a file.
Filter logs by log level and/or tags.
Enable or disable logs globally or selectively.
Support for asynchronous logging to minimize performance impact.

Usage

Import FLLogs in your Swift file:

import FLLogs

Create a Logging class and use different helper function for type of logs as .verbose, .debug, .info, .warning, .severe

import Foundation

               fileName: fileName, lineNumber: lineNumber,

}

               fileName: fileName, lineNumber: lineNumber,
               userInfo: userInfo)
}

public func logSevere(_ closure: @autoclosure @escaping () -> Any?, functionName: StaticString = #function, fileName: StaticString = #file, lineNumber: Int = #line, userInfo: [String: Any] = [:]) {
