NSHipster New Year's 2016

Greetings and salutations, NSHipsters!

As the year winds down, it's a tradition here at NSHipster to ask you, dear readers, to offer up your favorite tricks and tips from the past year as gifts to your fellow hipsters. With iOS 9, El Capitan, brand new watch- and tvOS's, and the open-sourcing of some minor Apple-related tech, there's bound to be lots to share.

Submit your favorite piece of Swift or @objc trivia, helpful hints, unexpected discoveries, useful workarounds, useless fascinations, or anything else you found cool this year. Just comment below!

If you need inspiration, try [the list from last year][2015], or [from the year before][2014], or [from the year before that][2013].

sindresorhus / StatusBarButton.swift
Last active Sep 21, 2018
Creates a NSStatusBarButton with proxy methods for the NSStatusItem methods, so you don't have to deal with that class anymore. Most of the NSStatusItem properties are deprecated, so it's much nicer to deal with the NSStatusBarButton directly.
View StatusBarButton.swift
final class AssociatedObject<T: Any> {
subscript(index: Any) -> T? {
get {
return objc_getAssociatedObject(index, Unmanaged.passUnretained(self).toOpaque()) as! T?
} set {
objc_setAssociatedObject(index, Unmanaged.passUnretained(self).toOpaque(), newValue, .OBJC_ASSOCIATION_RETAIN_NONATOMIC)

AvdLee / MutableProgress.swift
Last active Nov 18, 2020
Adding children to a Progress instance is easy, but removing is not possible by default. This could have been useful when you want to use a single Progress instance which can have different children over time. Using this custom class MutableProgress makes this possible. See:
View MutableProgress.swift
import UIKit
/// An additional class build on top of `Progress` to make it possible to also remove children from progress.
public final class MutableProgress: Progress {
public override var totalUnitCount: Int64 {
get {
return Int64(children.count)
set {
