Using an Instance of NSOrderedSet from Swift

gistfile1.swift

// How one might use NSMutableOrderedSet from Swift -- mainly an example of how to
// call Objective-C classes from Swift. Pretty much what one would expect.

var set = NSMutableOrderedSet()
set.addObject("foo");
set.addObject("bar");
set.addObjectsFromArray(["bar", "wee", "foo"])

for i in 0..set.count {
    println(set.objectAtIndex(i))
}

//Output
foo
bar
wee

var set = NSMutableOrderedSet()
set.add("foo");
set.add("bar");
set.addObjects(from: ["bar", "wee", "foo"])

print(set.count)
for i in 0..<set.count {
	print(set.object(at: i))
}
