Timer Set Up

Overview

MTimer offers a few basic settings. To start it, just call the start() function (See Timer Start-Up page). However, you might want to check the timer's current state - not just when it runs out, but perhaps every specific interval. To achieve this, you can use the publish() method

Available Methods

• func publish(every time: TimeInterval, tolerance: TimeInterval = 0.4, _ completion: @escaping (_ currentTime: MTime) -> ()) throws -> MTimer

  • Optional method with completion block that will be called every time interval
  • Configure the interval at which the timer's status will be published (see Timer State Observing page for the reference)

• func publish(every time: TimeInterval, tolerance: TimeInterval = 0.4, currentTime: Binding<MTime>) -> throws -> MTimer

  • Optional method with Binding property that will be updated every time interval
  • Configure the interval at which the timer's status will be published (see Timer State Observing page for the reference)

Step-by-Step Guide

1. Initialize a timer. See Timer Initialising page for the reference
2. (Optional) Call one of the publish methods

Example with completion block

@MainActor class ViewModel {
    @Published var time: MTime = .init()
    
    func startTimer() throws {
        try MTimer(.id)
            .publish(every: 1, tolerance: 0.7, onTimeUpdate)
    }
    func onTimeUpdate(_ time: MTime) {
        self.time = time
    }
}

Example with state value

struct ExampleView: View {
    @State var time: MTime = .init()
    
    var body: some View {
        Text("\(time.toTimeInterval())")
    }
    
    func startTimer() throws {
        try MTimer(.id)
            .publish(every: 1, tolerance: 0.7, currentTime: $time)
    }
}
