iOS SpriteKit Emitter particle frequency

Question

Is it possible to change how often a particle is emitted. For example, if I have one particle emitting, can I have it emit every 5 or 10 seconds?

I searched the documentation, but could not find anything. Is there a workaround? I would like to do something like this:

   emitter.particleBirthRate = 1
   emitter.particleBirthRateFrequency = 5  // this does not exist

I stay away from timers, there really isn't a need for them in SpriteKit

You have a built in timer function with the update func, or you can Just use actions to control your time.

what you are probably looking for is particle.resetSimulation()

I would do what you need to do like so

you can also put a key on your action and stop it by key name whenever needed

if let spark = self.childNode(withName: "sparkin") as? SKEmitterNode {
    
    self.spark = spark

    //set time here to how long in between restarting the emitter
    let waiter = SKAction.wait(forDuration: 5)
    let resetter = SKAction.run( { self.spark.resetSimulation() } )
    let seq = SKAction.sequence([waiter, resetter])
    let repeater = SKAction.repeatForever(seq)
    run(repeater)
}
