Swift alternative to performSelectorOnMainThread

Question

I want to reload my table data inside a block in this method:

import UIKit
import AssetsLibrary

class AlbumsTableViewController: UITableViewController {

           


        

Answer 1

Use GCD in lieu of performSelector variations.

dispatch_async(dispatch_get_main_queue()) {
        () -> Void in
        self.doSomething()
    }
