iOS Cell Registration & Reusing with Swift Protocol Extensions and Generics

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)

	import UIKit

	// This code is based on implementing the following:
	// Implement an algorithm to determine if a string has all unique characters. What if you cannot use any additional data structures?

	extension Character {
	func toString() -> String {
	return String(self)
	}
	}

	func debounce<T>(delay: TimeInterval, function: @escaping (T) -> Void, complete: @escaping () -> Void = { }) -> (T) -> Void {
	let queue = DispatchQueue(label: "Debouncer")
	var current: DispatchWorkItem?

	return { input in
	current?.cancel()
	let new = DispatchWorkItem {
	function(input)
	complete()
	}
