Swift ordered set data structure
Add the following to your Cartfile:
github "sendyhalim/OrderedSet"
Then run carthage update
import OrderedSet
let users = OrderedSet(elements: ["john", "doe"])
users.has(element: "john") // true
// Add element to set
users.append(element: "foo")
users.append(elements: ["foo", "bar"])
// Insert element at index, wont' do anything if "foo" is already in the set
users.insert(element: "foo", atIndex: 1)
// Remove element
users.remove(index: 1)
users.remove(element: "foo")
// Get number of elements
users.count
// Swap element position
users.swap(fromIndex: 1, toIndex: 3)
// For loop
for user in users {
print(user)
}MIT
