How to use MBProgressHUD with swift

Updated Answer:

let loadingNotification = MBProgressHUD.showAdded(to: view, animated: true)
loadingNotification.mode = MBProgressHUDMode.indeterminate
loadingNotification.label.text = "Loading"

To dismiss the ProgressHUD:

MBProgressHUD.hideAllHUDs(for: view, animated: true)

You can also try this approach which will keep the other activity running in the background allowing the UI to remain responsive, providing users with a better experience. This is the intended/recommended approach for using the MBProgressHUD.

let progressHUD = MBProgressHUD.showHUDAddedTo(self.view, animated: true)
progressHUD.labelText = "Loading..."

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_LOW, 0)) {

    // ...Run some task in the background here...

    dispatch_async(dispatch_get_main_queue()) {
        progressHUD.hide(true)

        // ...Run something once we're done with the background task...
    }
}

Swift 3 extensions

import Foundation
import MBProgressHUD
import QuartzCore

extension UITableViewController {
    func showHudForTable(_ message: String) {
        let hud = MBProgressHUD.showAdded(to: self.view, animated: true)
        hud.label.text = message
        hud.isUserInteractionEnabled = false
        hud.layer.zPosition = 2
        self.tableView.layer.zPosition = 1
    }
}

extension UIViewController {
    func showHud(_ message: String) {
        let hud = MBProgressHUD.showAdded(to: self.view, animated: true)
        hud.label.text = message
        hud.isUserInteractionEnabled = false
    }

    func hideHUD() {
        MBProgressHUD.hide(for: self.view, animated: true)
    }
}
