Impacts are all the same!

Hi!

You are declaring:
let lightImpactGenerator = UIImpactFeedbackGenerator()
let heavyImpactGenerator = UIImpactFeedbackGenerator()

Where, it seems to me, you need to be declaring:
let lightImpactGenerator = UIImpactFeedbackGenerator.init(style: .light)
let heavyImpactGenerator = UIImpactFeedbackGenerator.init(style: .heavy)

Also, you're going to need to code for the fact that .rigid and .soft styles are only available in ios13+.

Hey @filipesaz, I took a quick look and it seems that you're right! I haven't worked on FeedbackEffect in a while, but if you're willing to file a pull request I'd gladly code review and merge it in to make the appropriate changes. Does that sound like something you'd be interested din doing?
