Kevin, thanks for this.
I'm still getting an error in the MMDynamicTypeExtensions.swift, line 139,
for (element) in registeredElements {
let control = element as! UIView
Xcode is complaining that: Type NSMapTable<AnyObject, AnyObject> does not conform to protocol 'Sequence'
I don't believe I am even using this... but it was part of the original MM series...
