A common task when developing iOS apps is to register custom cell subclasses for both UITableView and UICollectionView. Well, that is if you don’t use Storyboards, of course.
Both UITableView and UICollectionView offer a similar API to register custom cell classes:
public func registerClass(cellClass: AnyClass?, forCellWithReuseIdentifier identifier: String)
public func registerNib(nib: UINib?, forCellWithReuseIdentifier identifier: String)

The diff output is more specific:
[I]f a whole block of text is moved, then all of it, rather than just the beginning and end, is detected as changed.
>The algorithm described here avoids these difficulties. It detects differences that correspond very closely to our intuitive notion of difference.
In this gist, I will discuss how I used the Multipeer Connectivity framework to create Open Source Selfie Stick. Open Source Selfie Stick is a free open-source iOS app that allows users to sync two devices over WiFi or Bluetooth and allows one to act as a remote control for the other's camera.
This tutorial assumes some knowledge of the Swift programming language and iOS development with Xcode.
Feel free to comment and point out any errors or improvements. If you'd like to help improve the app itself, make a fork from dev branch of the git repo. I plan on updating this document and explaining any newly added features or refactoring. As this gist w
