You can use flatMap(_:) in a similar manner to map(_:) in order to create an array by applying a transform to a sequence's elements. extension SequenceType { public func flatMap<T>(@noescape transform: (Self.Generator.Element) throws -> T?) rethrows -> [T] } The difference with...

Aggregate Applies an accumulator function over a sequence. int[] intList = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; int sum = intList.Aggregate((prevSum, current) => prevSum + current); // sum = 55 At the first step prevSum = 1 At the second prevSum = prevSum(at the first step) + 2 At the i-t...
