UIFeedbackGenerator object creation crashes on iOS 10.0

Question

Has anyone else encountered this? Specifically with an iPhone 6 running iOS 10.0 I'm getting consistent reports of the following crashing:

if #available(iOS 10.0, *) {
    UISelectionFeedbackGenerator()
}

Where it's not even being used, just created and it causes an EXC_BAD_ACCESS crash. The docs say it just fails silently if the device doesn't support it. Oddly enough if I change the check to iOS 10.0.1 it works fine.

Am I doing something wrong?

Weird, it's silently failing for me on a 6s. Try cleaning your project? — Jordan Smith, Oct 26 '16 at 22:00
@Jordan It fails silently for me on a 6s as well, but not a 6. Cleaned. — Doug Smith, Nov 03 '16 at 16:20
Also see a single crash on 10.0.0 (14A5309d) for iPhone 5s in production users. — Senry, Jul 25 '17 at 14:23

I saw a few seemingly random crashes in production when calling this function as well. When reviewing some old logs, I found that this was only occurring on iOS 10.0.0. As users updated past that, I stopped seeing the crash. I imagine it was some sort of internal UIKit bug that was fixed in iOS 10.0.1.
