So I am making this Snapchat look-a-like with stories where it has two stories. First one shows the whole story, and the other one shows the recently added. It's a bit buggy so sometimes when starting up it does not shows the images, but if I close the app and reopen it, it works. And sometimes it shows only some of the image, but it get fixed when close down and reopen the application. Anyways, here is the UIViewController code:
import Foundation
import UIKit
import Parse
import Player
import AVKit
import AVFoundation
extension NSDate {
func isGreaterThanDate(dateToCompare: NSDate) -> Bool {
//Declare Variables
var isGreater = false
//Compare Values
if self.compare(dateToCompare) == NSComparisonResult.OrderedDescending {
isGreater = true
}
//Return Result
return isGreater
}
func isLessThanDate(dateToCompare: NSDate) -> Bool {
//Declare Variables
var isLess = false
//Compare Values
if self.compare(dateToCompare) == NSComparisonResult.OrderedAscending {
isLess = true
}
//Return Result
return isLess
}
func equalToDate(dateToCompare: NSDate) -> Bool {
//Declare Variables
var isEqualTo = false
//Compare Values
if self.compare(dateToCompare) == NSComparisonResult.OrderedSame {
isEqualTo = true
}
//Return Result
return isEqualTo
}
func addDays(daysToAdd: Int) -> NSDate {
let secondsInDays: NSTimeInterval = Double(daysToAdd) * 60 * 60 * 24
let dateWithDaysAdded: NSDate = self.dateByAddingTimeInterval(secondsInDays)
//Return Result
return dateWithDaysAdded
}
func addHours(hoursToAdd: Int) -> NSDate {
let secondsInHours: NSTimeInterval = Double(hoursToAdd) * 60 * 60
let dateWithHoursAdded: NSDate = self.dateByAddingTimeInterval(secondsInHours)
//Return Result
return dateWithHoursAdded
}
}
class ViewStoryModalViewController: UIViewController, PlayerDelegate {
func delay(delay:Double, closure:()->()) {

Please, if anyone has any tips that could help me make this more stable or other tips, tell me. Thanks in advanced :)
