I've had alarm issues as well recently, and I think in my case it may have something to do with either (1) "Attention Aware Features" that will silence alarms if it thinks you're using / looking at the phone, or (2) wearing my watch and having it think that I was silencing alarms by covering or touching the screen.

I turned off the attention aware features and also flipped off "Push Alerts from iPhone" for the Clock app on my watch. My distrust at this point is so bad that I just don't wear the watch to sleep even though I love the sleep tracking features.

It's ridiculous that a bug with alarms is even a thing, and also something that's hard to troubleshoot when I'm half-awake.
