--- Comment #5 from Luke Mizuhashi <luke.mizuhashi at abilityapp.org> ---
I'm having a similar issue:

I'm writing an app that allows people with disabilities to search for places and services that are accessible to their particular requirements (vis. search for hotels that work with your accessibility device, etc.)

So, we will have a lot of end users who have computers with cameras attached via USB, more than two cameras, perhaps zero, etc.

And yet, our app needs a button to cycle through media streams. So, hard-coding around the `navigator.mediaDevices.getUserMedia({ video: { facingMode: 'user' }})` pattern won't be ideal.

We would like to use something like `navigator.mediaDevices.enumerateDevices().then(deviceInfoList => cache = deviceInfoList);`

followed by:

`someElement.on('click', () => { navigator.mediaDevices.getUserMedia({ video: { deviceId: cache.nextId() }}) }`, but because the device ID's reported by Safari change unpredictably inside a single session we are unable to use device ID reliably.

We've tested on iOS 11.4 (15F79) with Safari 5.0
