Notes

Sequence protocol in Swift

In Swift, to be able to iterate through MSMapElementCollection using a for-in loop, you will need to add the following extension that conforms to the required Sequence protocol.

extension MSMapElementCollection: Sequence {
    public func makeIterator() -> NSFastEnumerationIterator {
        return NSFastEnumerationIterator(self)
    }
}
