How To Do UIActionSheet in iOS Swift? Here is my code for coding UIActionSheet.

@IBAction func downloadSheet(sender: AnyObject)
{
    let optionMenu = UIAlertController(title: nil, message: "Choose Option", preferredStyle: .actionSheet) 

    let saveAction = UIAlertAction(title: "Save", style: .default, handler: 
    {
        (alert: UIAlertAction!) -> Void in
        println("Saved")
    })

    let deleteAction = UIAlertAction(title: "Delete", style: .default, handler:
    {
        (alert: UIAlertAction!) -> Void in
        println("Deleted")
    })

    let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: 
    {
        (alert: UIAlertAction!) -> Void in
        println("Cancelled")
    })
    optionMenu.addAction(deleteAction)
    optionMenu.addAction(saveAction)
    optionMenu.addAction(cancelAction)
    self.presentViewController(optionMenu, animated: true, completion: nil)
}

I hope my Code is clear... I am welcome better suggestion for this code.

Your Approach is fine, but you can add UIActionSheet with other way with ease.

You can add UIActionSheetDelegate in UIViewController` like

class ViewController: UIViewController ,UIActionSheetDelegate

Set you method like, 

@IBAction func downloadSheet(sender: AnyObject)
{

    let actionSheet = UIActionSheet(title: "Choose Option", delegate: self, cancelButtonTitle: "Cancel", destructiveButtonTitle: nil, otherButtonTitles: "Save", "Delete")

    actionSheet.showInView(self.view)
}

You can get your button index when it clicked like 

func actionSheet(actionSheet: UIActionSheet, clickedButtonAtIndex buttonIndex: Int)
{
    println("\(buttonIndex)")
    switch (buttonIndex){

    case 0:
        println("Cancel")
    case 1:
        println("Save")
    case 2:
        println("Delete")
    default:
        println("Default")
        //Some code here..

    }
}

Update 1: for iOS8+

    //Create the AlertController and add Its action like button in Actionsheet
    let actionSheetControllerIOS8: UIAlertController = UIAlertController(title: "Please select", message: "Option to select", preferredStyle: .ActionSheet)

    let cancelActionButton = UIAlertAction(title: "Cancel", style: .cancel) { _ in
        print("Cancel")
    }
    actionSheetControllerIOS8.addAction(cancelActionButton)

    let saveActionButton = UIAlertAction(title: "Save", style: .default)
        { _ in
           print("Save")
    }
    actionSheetControllerIOS8.addAction(saveActionButton)

    let deleteActionButton = UIAlertAction(title: "Delete", style: .default)
        { _ in
            print("Delete")
    }
    actionSheetControllerIOS8.addAction(deleteActionButton)
    self.present(actionSheetControllerIOS8, animated: true, completion: nil)

Updated for Swift 4

Works for iOS 11

Some of the other answers are okay but I ended up mixing and matching a few of them to rather come up with this : 

@IBAction func showAlert(sender: AnyObject) {
    let alert = UIAlertController(title: "Title", message: "Please Select an Option", preferredStyle: .actionSheet)

    alert.addAction(UIAlertAction(title: "Approve", style: .default , handler:{ (UIAlertAction)in
        print("User click Approve button")
    }))

    alert.addAction(UIAlertAction(title: "Edit", style: .default , handler:{ (UIAlertAction)in
        print("User click Edit button")
    }))

    alert.addAction(UIAlertAction(title: "Delete", style: .destructive , handler:{ (UIAlertAction)in
        print("User click Delete button")
    }))

    alert.addAction(UIAlertAction(title: "Dismiss", style: .cancel, handler:{ (UIAlertAction)in
        print("User click Dismiss button")
    }))

    self.present(alert, animated: true, completion: {
        print("completion block")
    })
}

Enjoy :)

UIActionSheet is deprecated in iOS 8.

I am using following:

// Create the AlertController
let actionSheetController = UIAlertController(title: "Please select", message: "How you would like to utilize the app?", preferredStyle: .ActionSheet)

// Create and add the Cancel action
let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { action -> Void in
    // Just dismiss the action sheet
}
actionSheetController.addAction(cancelAction)

// Create and add first option action
let takePictureAction = UIAlertAction(title: "Consumer", style: .Default) { action -> Void in
    self.performSegueWithIdentifier("segue_setup_customer", sender: self)
}
actionSheetController.addAction(takePictureAction)

// Create and add a second option action
let choosePictureAction = UIAlertAction(title: "Service provider", style: .Default) { action -> Void in
    self.performSegueWithIdentifier("segue_setup_provider", sender: self)
}
actionSheetController.addAction(choosePictureAction)

// We need to provide a popover sourceView when using it on iPad
actionSheetController.popoverPresentationController?.sourceView = sender as UIView

// Present the AlertController
self.presentViewController(actionSheetController, animated: true, completion: nil)

    print("Cancel")
}
actionSheetController.addAction(cancelActionButton)

let saveActionButton = UIAlertAction(title: "Save", style: .default) { action -> Void in
    print("Save")
}
actionSheetController.addAction(saveActionButton)

let deleteActionButton = UIAlertAction(title: "Delete", style: .default) { action -> Void in
    print("Delete")
}
actionSheetController.addAction(deleteActionButton)
self.present(actionSheetController, animated: true, completion: nil)

Updated for Swift 3.x, Swift 4.x, Swift 5.x

// create an actionSheet
let actionSheetController: UIAlertController = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)

// create an action
let firstAction: UIAlertAction = UIAlertAction(title: "First Action", style: .default) { action -> Void in

    print("First Action pressed")
}

let secondAction: UIAlertAction = UIAlertAction(title: "Second Action", style: .default) { action -> Void in

    print("Second Action pressed")
}

let cancelAction: UIAlertAction = UIAlertAction(title: "Cancel", style: .cancel) { action -> Void in }

// add actions
actionSheetController.addAction(firstAction)
actionSheetController.addAction(secondAction)
actionSheetController.addAction(cancelAction)


// present an actionSheet...
// present(actionSheetController, animated: true, completion: nil)   // doesn't work for iPad

actionSheetController.popoverPresentationController?.sourceView = yourSourceViewName // works for both iPhone & iPad

present(actionSheetController, animated: true) {
    print("option menu presented")

Generetic Action Sheet working for Swift 4, 4.2, 5

If you like a generic version that you can call from every ViewController and in every project try this one: 

class Alerts {
 static func showActionsheet(viewController: UIViewController, title: String, message: String, actions: [(String, UIAlertActionStyle)], completion: @escaping (_ index: Int) -> Void) {
    let alertViewController = UIAlertController(title: title, message: message, preferredStyle: .actionSheet)
    for (index, (title, style)) in actions.enumerated() {
        let alertAction = UIAlertAction(title: title, style: style) { (_) in
            completion(index)
        }
        alertViewController.addAction(alertAction)
     }
     viewController.present(alertViewController, animated: true, completion: nil)
    }
}

Call like this in your ViewController. 

    var actions: [(String, UIAlertActionStyle)] = []
    actions.append(("Action 1", UIAlertActionStyle.default))
    actions.append(("Action 2", UIAlertActionStyle.destructive))
    actions.append(("Action 3", UIAlertActionStyle.cancel))

    //self = ViewController
    Alerts.showActionsheet(viewController: self, title: "D_My ActionTitle", message: "General Message in Action Sheet", actions: actions) { (index) in
        print("call action \(index)")
        /*
         results
         call action 0
         call action 1
         call action 2
         */
    }

Attention: Maybe you're wondering why I add Action 1/2/3 but got results like 0,1,2. In the line for (index, (title, style)) in actions.enumerated() I get the index of actions. Arrays always begin with the index 0. So the completion is 0,1,2.

If you like to set a enum, an id or another identifier I would recommend to hand over an object in parameter actions.

The Old Way: UIActionSheet

let actionSheet = UIActionSheet(title: "Takes the appearance of the bottom bar if specified; otherwise, same as UIActionSheetStyleDefault.", delegate: self, cancelButtonTitle: "Cancel", destructiveButtonTitle: "Destroy", otherButtonTitles: "OK")
actionSheet.actionSheetStyle = .Default
actionSheet.showInView(self.view)

// MARK: UIActionSheetDelegate

func actionSheet(actionSheet: UIActionSheet, clickedButtonAtIndex  buttonIndex: Int) {
switch buttonIndex {
    ...
   }
}

The New Way: UIAlertController

let alertController = UIAlertController(title: nil, message: "Takes the appearance of the bottom bar if specified; otherwise, same as UIActionSheetStyleDefault.", preferredStyle: .ActionSheet)

let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { (action) in
  // ...
 }
 alertController.addAction(cancelAction)

let OKAction = UIAlertAction(title: "OK", style: .Default) { (action) in
   // ...
}
alertController.addAction(OKAction)

let destroyAction = UIAlertAction(title: "Destroy", style: .Destructive) { (action) in
println(action)
}
alertController.addAction(destroyAction)

self.presentViewController(alertController, animated: true) {
// ...
}

You can use following code for open actionSheet in Swift

        let alert = UIAlertController(title: enter your title, message: "Enter your messgage. ", preferredStyle: UIAlertControllerStyle.Alert)

        alert.addTextFieldWithConfigurationHandler(configurationTextField)

        alert.addAction(UIAlertAction(title: "Close", style: UIAlertActionStyle.Cancel, handler:{ (UIAlertAction)in
            print("User click Cancel button")
        }))

        alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler:{ (UIAlertAction)in
            print("User click Ok button")
