ViewController does not conform to protocol on Swift - ios

Question

I'm having an issue with calling a delegate in my class. I have a SideBarTableController and SideBar.swift file.It was working fine until I logged off and back in. Here is the code. It keeps telling me that 'ViewController' does not conform to protocol 'SideBarDelegate'. I'm new to programming so sorry in advance if this is vague. Anything will help thanks!
import UIKit
import iAd
class ViewController: UIViewController, SideBarDelegate { -----This is where the error is happening
#IBOutlet var menuTab: UIButton! // Menu Tab
#IBOutlet var businessButton: UIButton! // Business Button
#IBOutlet var adBanner: ADBannerView! // Banner Ad
#IBOutlet var imageView: UIImageView! // Main Image in middle
var topHeader: UIImageView! // Utility header
var sideBar:SideBar = SideBar() // Side Bar
override func viewDidLoad() {
super.viewDidLoad()
// Function for menu
// menuTab.addTarget(self, action: "buttonPressed", forControlEvents: UIControlEvents.TouchUpInside)
func menuTab(sender: UIButton){
sideBar = SideBar(sourceView: self.view, menuItems: ["Home", "Business Directory", "Classifieds", "Featured News", "Jobs", "Restaurants", "Sports"])
sideBar.delegate = self }
// Gives the screen dimensions
let screenSize: CGRect = UIScreen.mainScreen().bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height
// Side bar action and text
sideBar = SideBar(sourceView: self.view, menuItems: ["Home", "Business Directory", "Classifieds", "Featured News", "Jobs", "Restaurants", "Sports"])
sideBar.delegate = self
// Utility Background
var topHeader = UIView(frame: CGRectMake(0, 0, screenWidth, 17))
topHeader.backgroundColor = UIColor(white: 0.0, alpha: 1.0)
self.view.addSubview(topHeader)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// Side Bar funcion
func sideBarDidSelectButtonAtIndex(index: Int) {
if index == 0{
imageView.backgroundColor = UIColor.redColor()
imageView.image = nil
} else if index == 1{
imageView.backgroundColor = UIColor.clearColor()
imageView.image = UIImage(named: "image2")
}
}
// Status bar style (white)
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return UIStatusBarStyle.LightContent
}
}
Here is where I called the SideBarDelegate
import UIKit
#objc protocol SideBarDelegate{
func sideBarDidSelectButtonAtIndex(index:Int)
func sideBarWillClose()
func sideBarWillOpen()
}
class SideBar: NSObject, SideBarTableViewControllerDelegate {
let barWidth:CGFloat = 176.0
let sideBarTableViewTopInset:CGFloat = 64.0
let sideBarContainerView:UIView = UIView()
let sideBarTableViewController:SideBarTableViewController = SideBarTableViewController()
let originView:UIView!
var animator:UIDynamicAnimator!
var delegate:SideBarDelegate?
var isSideBarOpen:Bool = false
override init() {
super.init()
}
init(sourceView:UIView, menuItems:Array<String>){
super.init()
originView = sourceView
sideBarTableViewController.tableData = menuItems
setupSideBar()
animator = UIDynamicAnimator(referenceView: originView)
let showGestureRecognizer:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: "handleSwipe:")
showGestureRecognizer.direction = UISwipeGestureRecognizerDirection.Right
originView.addGestureRecognizer(showGestureRecognizer)
let hideGestureRecognizer:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: "handleSwipe:")
hideGestureRecognizer.direction = UISwipeGestureRecognizerDirection.Left
originView.addGestureRecognizer(hideGestureRecognizer)
}
func setupSideBar(){
sideBarContainerView.frame = CGRectMake(-barWidth - 1, originView.frame.origin.y, barWidth, originView.frame.size.height)
sideBarContainerView.backgroundColor = UIColor.clearColor()
sideBarContainerView.clipsToBounds = false
originView.addSubview(sideBarContainerView)
let blurView:UIVisualEffectView = UIVisualEffectView(effect: UIBlurEffect(style: UIBlurEffectStyle.Light))
blurView.frame = sideBarContainerView.bounds
sideBarContainerView.addSubview(blurView)
sideBarTableViewController.delegate = self
sideBarTableViewController.tableView.frame = sideBarContainerView.bounds
sideBarTableViewController.tableView.clipsToBounds = false
sideBarTableViewController.tableView.separatorStyle = UITableViewCellSeparatorStyle.None
sideBarTableViewController.tableView.backgroundColor = UIColor.clearColor()
sideBarTableViewController.tableView.scrollsToTop = false
sideBarTableViewController.tableView.contentInset = UIEdgeInsetsMake(sideBarTableViewTopInset, 0, 0, 0)
sideBarTableViewController.tableView.reloadData()
sideBarContainerView.addSubview(sideBarTableViewController.tableView)
}
func handleSwipe(recognizer:UISwipeGestureRecognizer){
if recognizer.direction == UISwipeGestureRecognizerDirection.Left{
showSideBar(false)
delegate?.sideBarWillClose()
}else{
showSideBar(true)
delegate?.sideBarWillOpen()
}
}
func showSideBar(shouldOpen:Bool){
animator.removeAllBehaviors()
isSideBarOpen = shouldOpen
let gravityX:CGFloat = (shouldOpen) ? 0.5 : -0.5
let magnitude:CGFloat = (shouldOpen) ? 20 : -20
let boundaryX:CGFloat = (shouldOpen) ? barWidth : -barWidth - 1
let gravityBehavior:UIGravityBehavior = UIGravityBehavior(items: [sideBarContainerView])
gravityBehavior.gravityDirection = CGVectorMake(gravityX, 0)
animator.addBehavior(gravityBehavior)
let collisionBehavior:UICollisionBehavior = UICollisionBehavior(items: [sideBarContainerView])
collisionBehavior.addBoundaryWithIdentifier("sideBarBoundary", fromPoint: CGPointMake(boundaryX, 20), toPoint: CGPointMake(boundaryX, originView.frame.size.height))
animator.addBehavior(collisionBehavior)
let pushBehavior:UIPushBehavior = UIPushBehavior(items: [sideBarContainerView], mode: UIPushBehaviorMode.Instantaneous)
pushBehavior.magnitude = magnitude
animator.addBehavior(pushBehavior)
let sideBarBehavior:UIDynamicItemBehavior = UIDynamicItemBehavior(items: [sideBarContainerView])
sideBarBehavior.elasticity = 0.3
animator.addBehavior(sideBarBehavior)
}
func sideBarControlDidSelectRow(indexPath: NSIndexPath) {
delegate?.sideBarDidSelectButtonAtIndex(indexPath.row)
}
}

Answer 1

Your SideBarDelegate protocol specifies some methods that must be implemented in order to conform to that protocol. So look at the definition of that protocol, identify what methods are defined therein, and then implement them in your ViewController class.
It's possible you missed one of the functions defined in that protocol, or perhaps you mistyped something in the definition of sideBarDidSelectButtonAtIndex. We cannot say without seeing the definition of this protocol.
Update:
You subsequently supplied the definition of your protocol. It defines two additional functions that you have not implemented in your view controller:
func sideBarWillClose()
func sideBarWillOpen()
You also must implement these two functions in your view controller (even if you put nothing into them).
