Modern API for Timer

Easy to use yet powerful Timer library. Keep your code clean

Try demo we prepared

Timer is a free and open-source library dedicated for Swift that makes the process of handling timers easier and much cleaner.

• Improves code quality. Start timer using the publish().start() method. Stop the timer with stop(). Simple as never.
• Run your timer in both directions. Our Timer can operate in both modes (increasing or decreasing).
• Supports background mode. Don’t worry about the timer when the app goes into the background. We handled it!
• And much more. Our library allows you to convert the current time to a string or to display the timer progress in no time.

Getting Started

✋ Requirements

⏳ Installation

Swift package manager

1. Initialise the timer

Call the publish() method that has three parameters:

• time – The number of seconds between firings of the timer.
• tolerance – The number of seconds after the update date that the timer may fire.
• currentTime – The current timer time.

  try! MTimer.publish(every: 1, currentTime: $currentTime)

2. Start the timer

Start the timer using the start() method. You can customise the start and end time using the parameters of this method.

  try! MTimer
      .publish(every: 1, currentTime: $currentTime)
      .start(from: .init(minutes: 21, seconds: 37), to: .zero)

3. (Optional) Observe TimerStatus and TimerProgress

You can observe changes in both values by calling either of the methods

  try! MTimer
      .publish(every: 1, currentTime: $currentTime)
      .bindTimerStatus(isTimerRunning: $isTimerRunning)
      .bindTimerProgress(progress: $timerProgress)
      .start(from: .init(minutes: 21, seconds: 37), to: .zero)

4. Stop the timer

Timer can be stopped with stop() method.

  MTimer.stop()

5. Additional timer controls

• Once stopped, the timer can be resumed – simply use the resume() method.

  try! MTimer.resume()

• To stop and reset the timer to its initial values, use the reset() method.

  MTimer.reset()

6. Displaying the current time as String

You can convert the current MTime to String by calling the toString() method. Use the formatter parameter to customise the output.

  currentTime.toString {
      $0.unitsStyle = .full
      $0.allowedUnits = [.hour, .minute]
      return $0
  }

7. Creating more timer instances

Create a new instance of the timer and assign it to a new variable. Use the above functions directly with it

  let newTimer = MTimer.createNewInstance()

  try! newTimer
      .publish(every: 1, currentTime: $currentTime)
      .start()

  newTimer.stop()
