I have the following structure
aSectionArray = [[objA, objB, objC], [obj1, obj2, obj3], [objX, objY, objZ]]
objA is having a bool, say isEnabled.
I need to filter the aSectionArray based this bool (say isEnabled == true).
Help needed.

1Not clear if you're wanting to flatten and filter as Eric suggests, or return only the elements of the outer array that have a matching element, or an array of arrays of matching objects, or...David Berry– David Berry2016-07-20 20:20:03 +00:00Commented Jul 20, 2016 at 20:20

You could use flatten() and filter, like this (Swift 2):
let result = aSectionArray.flatten().filter { $0.isEnabled }
it will give you the objects where isEnabled is true.
We use flatten() to make the 2D array into a 1D array, and we use filter to get the objects where the closure verifies.
In Swift 3 (Xcode 8 beta 6) flatten has become joined:
let result = aSectionArray.joined().filter { $0.isEnabled }
