Convert 2DArray to Array of Sets in Swift

Question

How does one convert a 2D array to an array of sets in Swift, without using NSArray or NSSet?

I would like to go from [[UIView]] to var convertedSetsArray: [Set<UIView>]

Use something like this (assuming that views is an array of array of UIViews):

let result = views.map { Set($0) }

the type of views is [[UIView]], the result is Array<Set<UIView>>, so you didn't use any "NS" related types.
