Just recently, I was facing a lot of quirks on iOS introduced by the latest iOS 10 update. There’s a lot of discussion going on here iOS 10 compatibility and here https://github.com/meteor/meteor/issues/7772#issuecomment-248606858.
There are work-arounds for most, if not all, of the problems. But it is not easy to find them, as they are wide-spread across these two threads (and maybe others I don’t know).
I really love the excellent Meteor Guide, which is a great resource for many complex questions. So I’d like to recommend to extend the guide by an iOS 10 work-around chapter. Even if some of the problems will be fixed in the latest Meteor updates, not all of us are able to do these updates as they are still on older Meteor versions (like I am).
I would be happy to contribute to this Guide chapter, if needed.
