One of the first things someone new to iOS Development finds is that dealing with the keyboard is trickier
than they think it should be. Simply changing the scrolling extents of a UITableView (or UIScrollView, or 
UICollectionView) that is partially covered by they keyboard reveals a lot about the internals of how iOS
works and highlights various "gotchas" that need to be considered.

There are various ways to know that a keyboard has been shown - but observing some specific notifications
provides a reliable way to allow you to modify your views to deal with it.

This code helps using ObjectMapper with RealmSwift.

RealmSwift uses List<T> collection for "to many" relashionships and RealmOptional<T> for optional primitive types, but ObjectMapper can't map directly to List<T> and RealmOptional<T>.

With this operators you can properly define RealmSwift's relashionships and optional properties and use <- operator to map them.
