This article aims to describe how to hook Swift functions.

Thanks to help from @NightwindDev for discussion and testing.

UITableView Simple Template

Small Sample

import UIKit

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

	#include <Preferences/PSListController.h>

	@interface PSListController (JSON)

	- (NSMutableArray )loadSpecifiersFromJSONName:(NSString )name target:(PSListController *)target;
	- (NSMutableArray )loadSpecifiersFromJSONName:(NSString )name target:(PSListController )target bundle:(NSBundle )bundle;

	@end

	/* if you cannot use private frameworks, you could probably look into MPVolumeView*/
	/* but i never tried it myself. you may also look into AVAudioSession's outputVolume*/
