Haptic engine iPhone stronger impact

Question

I have this function which creates haptic impact:

func generateVibration() {

    let generator = UIImpactFeedbackGenerator(style: .heavy)
    generator.impactOccurred()
}

I would like to make the impact stronger. Thanks for your help.

Answer 1

func generateVibration() {

    let generator = UIImpactFeedbackGenerator(style: .heavy)
    generator.impactOccurred()
    generator.impactOccurred()
}

The more times you call generator.impactOccured(), the stronger the impact will be.
