How it works

How it works

iLog is a simple log manager that uses a superfast SqlLite database to store your logs.

  • Four types of log: debug, info, warn, error
  • Logs file, function and line
  • Really Fast!
  • Log drivers: Console and Sql drivers included. You can write your own driver if you need
  • Nice log viewer interface
  • Customizable
  • Well documented
  • and more…

Requirements

  • Swift 3
  • iOS 9+

What’s new in version 1.3.0

  • Huge performance improvement. Logging happens in a unique background queue
  • New log viewer with full text search and log level filtering

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate iLog into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'
use_frameworks!

pod 'iLog'

Then, run the following command:

$ pod install

If you want to use our log viewer add this line to your Podfile:

pod 'iLog/UI'

iLog/UI requires minimum iOS 9.

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate SideMenu into your Xcode project using Carthage, specify it in your Cartfile:

github "leoneparise/iLog" "master"

Usage

log(_ level:LogLevel, _ message:String)

Under the hood, this functions uses LogManager shared instance to log your data. LogManager is the iLog’s main class and has the following signature:

public class LogManager {

  /// LogManager level
  public var level:LogLevel = .debug {

  /// Callback used to receive a log event. This function is called when ANY LogManager saves a log.
  public var didLog: DidLogCallback?

  /// Drivers
  public var drivers: [LogDriver]

  /// Main driver is always the first driver in drivers attribute.
  public var mainDriver: LogDriver?

  /// Share instance. Can be customized to meed your needs
  public static var shared: LogManager

  /// Get all logs. Depends if the mainDriver provides this feature
  public func all(level levelOrNil: LogLevel? = nil, offset: Int = 0) -> [LogEntry]?

  /// Log into all drivers
  public func log(file: String = #file, line: UInt = #line, function: String = #function, level: LogLevel = .debug, message: String)

  /// Clear all logs
  public func clear() {
}

Examples

log(.debug, "My debug message")
log(.info, "My info message")
log(.error, "Something really bad happened...")

To disable the log database in prodution, put this code in your application(_:didFinishLaunchWithOptions:) method:

if let sqlLogDriver = SqlLogDriver(), let consoleLogDriver = ConsoleLogDriver() {
    #if DEBUG
        LogManager.shared.drivers = [sqlLogDriver, consoleLogDriver]
    #else
        LogManager.shared.drivers = [consoleLogDriver]
    #endif
}

If you want to receive log events, you can use the NotificationCenter and listen to Notification.Name.LogManagerDidLog notification. The object is the LogEntry struct used to store logs. You can achieve the same result setting the function didLog in ANY LogManager instance.

Implement your own driver

LogDriver protocol is defined as:

public protocol LogDriver:class {
    /// Function called when a log is send by this driver
    var didLog: DidLogCallback? { get set }

    /// Minimum level to log **debug < info < warn < error**
    var level:LogLevel { get set }

    /**
     Logs a LogEntry. This is the main function of this driver

     - parameter entry: log entry
     */
    func log(entry:LogEntry)

    /**
     Get all logs stored by this driver. **Some drivers doesn't offer log history** (eg: ConsoleLogDriver) returning `nil`.

     - parameter level: log level to filter
     - parameter offset: offset to the history
     - returns: Array of `LogEntry` if history is supported or `nil` otherwise
     */
    func all(level levelOrNil:LogLevel?, offset:Int) -> [LogEntry]?

    /**
     Store logs in another service. The handler function must call the callback to tell this driver 
     the the storing was completed with success. The driver must handle what should be stored or not.

     **Some drivers doesn't suppor store (eg: ConsoleLogDriver)**

     - parameter: handler Store function handler
     */
    func store(_ handler: StoreHandler)

    /// Clear logs. **Some drivers doesn't support clear**
    func clear()
}

Some drivers may support all features as history, store or clear. If your driver don’t support these features, leave the implementation blank or return nil. Check ConsoleLogDriver and SqlLodDriver to know more.

Log Viewer

To view your logs you can use our Log Viewer view controller. Just instantiate our LogViewerViewController and present in your code:

self.present(LogViewerViewController(), animated: true)

Store logs in your backend

You can send logs to your server. SqlLogDriver() must be set as the mainDriver in you LogManager instance. Call the method storeLogsInBackground(application:handler:) on applicationDidEnterBackground(_ application:), provide your own store handler and we will take care of the rest. 😉 Ex:

func applicationDidEnterBackground(_ application: UIApplication) {
  LogManager.shared.storeLogsInBackground(application:application) { (entries, callback) in
    // Call your api with entries
    callback(success)
  }
}
