Usage example

@StateObject style

import SwiftUI
import WatchShaker

struct ContentView: View {
    
    @StateObject var shaker:WatchShaker = WatchShaker(shakeSensibility: .shakeSensibilityNormal, delay: 0.2)
    
    var body: some View {
        VStack {
            if shaker.isShakerAvailable {
                Text("I'm shook! ⌚️⌚️⌚️")
                Text("\(shaker.shake.sensibility)")
                Text("\(shaker.shake.direction)")
            }
        }
    }
}

Closure Style

import WatchKit
import Foundation
import WatchShaker

class InterfaceController: WKInterfaceController {
    
    var shaker:WatchShaker = WatchShaker(shakeSensibility: .shakeSensibilityNormal, delay: 0.2)
    
    override func awake(withContext context: Any?) {
        super.awake(withContext: context)
    }
    
    override func willActivate() {
        super.willActivate()
        
        shaker.start()
        
        shaker.startWatchShakerUpdates = { shakeSensibility, error in
            
            guard error == nil else
            {
                print(error?.localizedDescription)
                return
            }
            print("I'm shook! ⌚️⌚️⌚️")
        }
    }
    
    override func didDeactivate() {
        super.didDeactivate()
        shaker.stop()
    }

}

Delegate Style

import WatchKit
import Foundation


class InterfaceController: WKInterfaceController {

    override func awake(withContext context: Any?) {
        super.awake(withContext: context)
        // Configure interface objects here.
    }

    var shaker:WatchShaker = WatchShaker(shakeSensibility: .shakeSensibilityNormal, delay: 0.2)

    override func willActivate() {

        super.willActivate()
        shaker.delegate = self
        shaker.start()
    }

    override func didDeactivate() {

        super.didDeactivate()
        shaker.stop()

    }

}

extension InterfaceController: WatchShakerDelegate
{
    func watchShaker(_ watchShaker: WatchShaker, didShakeWith sensibility: ShakeSensibility) {
        print("I'm shook! ⌚️⌚️⌚️")
    }

    func watchShaker(_ watchShaker: WatchShaker, didFailWith error: Error) {
        print(error.localizedDescription)
    }
}

Optional Directions

If you interested you can get the direction of the shake on the didShakeWith method.

func watchShaker(_ watchShaker: WatchShaker, didShakeWith sensibility: ShakeSensibility, 
                     direction: ShakeDirection) {
    print("I'm shook! ⌚️⌚️⌚️ \(direction)")
}

ShakeDirection is a simple enum who gives you up, down, left or right direction. The image bellow is the way used to determine what is each direction.

This gentleman bellow for example, is clearly doing a shake with ShakeDirection.shakeDirectionRight 😂
