Select Multiple Collection View Cells and Store in Array - ios

Question

I'm working on an onboarding flow for my iOS App in Swift. I'd like to allow users to tap other users in a collection view and have it follow those users. I need the collection view to be able to allow multiple cells to be selected, store the cells in an array and run a function once the users taps the next button. Here's my controller code:
class FollowUsers: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate {
var tableData: [SwiftyJSON.JSON] = []
#IBOutlet weak var collectionView: UICollectionView!
#IBOutlet weak var loadingView: UIView!
private var selectedUsers: [SwiftyJSON.JSON] = []
override func viewDidLoad() {
super.viewDidLoad()
self.getCommunities()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func getUsers() {
Alamofire.request(.GET, "url", parameters: parameters)
.responseJSON {response in
if let json = response.result.value {
let jsonObj = SwiftyJSON.JSON(json)
if let data = jsonObj.arrayValue as [SwiftyJSON.JSON]? {
self.tableData = data
self.collectionView.reloadData()
self.loadingView.hidden = true
}
}
}
}
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return self.tableData.count
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell: UserViewCell = collectionView.dequeueReusableCellWithReuseIdentifier("userCell", forIndexPath: indexPath) as! UserViewCell
let rowData = tableData[indexPath.row]
if let userName = rowData["name"].string {
cell.userName.text = userName
}
if let userAvatar = rowData["background"].string {
let url = NSURL(string: userAvatar)
cell.userAvatar.clipsToBounds = true
cell.userAvatar.contentMode = .ScaleAspectFill
cell.userAvatar.hnk_setImageFromURL(url!)
}
cell.backgroundColor = UIColor.whiteColor()
return cell
}
func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {
let cell: UserViewCell = collectionView.dequeueReusableCellWithReuseIdentifier("userCell", forIndexPath: indexPath) as! UserViewCell
let rowData = tableData[indexPath.row]
let userName = rowData["name"].string
let userId = rowData["id"].int
selectedUsers.append(rowData[indexPath.row])
print("Cell \(userId) \(userName) selected")
}
}

Answer 1

override func viewDidLoad() {
super.viewDidLoad()
collection.dataSource = self
collection.delegate = self
collection.allowsMultipleSelection = true
self.getCommunities()
}
You should be able to make multiple selections with this.
