You can use MBProgressHUD to show a toast like android. After adding MBProgressHUD you can display a toast by this way

        let progressHUD = MBProgressHUD.showAdded(to: self.view, animated: true)

        progressHUD.mode = MBProgressHUDMode.text

        progressHUD.detailsLabel.text = "Your message here"

        progressHUD.margin = 10.0

        progressHUD.offset.y = 150.0

        progressHUD.isUserInteractionEnabled = false

        progressHUD.removeFromSuperViewOnHide = true

        progressHUD.hide(animated: true, afterDelay: 3.0)

You can use this function to display toast message in iOS. Just create the extension on the view and call this method with the message.

Swift 4

extension UIView {



    func displayToast(_ message : String) {



        guard let delegate = UIApplication.shared.delegate as? AppDelegate, let window = delegate.window else {

            return

        }

        if let toast = window.subviews.first(where: { $0 is UILabel && $0.tag == -1001 }) {

            toast.removeFromSuperview()

        }



        let toastView = UILabel()

        toastView.backgroundColor = UIColor.black.withAlphaComponent(0.7)

        toastView.textColor = UIColor.white

        toastView.textAlignment = .center

        toastView.font = UIFont(name: "Font-name", size: 17)

        toastView.layer.cornerRadius = 25

        toastView.text = message

        toastView.numberOfLines = 0

        toastView.alpha = 0

        toastView.translatesAutoresizingMaskIntoConstraints = false

        toastView.tag = -1001



        window.addSubview(toastView)



        let horizontalCenterContraint: NSLayoutConstraint = NSLayoutConstraint(item: toastView, attribute: .centerX, relatedBy: .equal, toItem: window, attribute: .centerX, multiplier: 1, constant: 0)



        let widthContraint: NSLayoutConstraint = NSLayoutConstraint(item: toastView, attribute: .width, relatedBy: .equal, toItem: nil, attribute: .width, multiplier: 1, constant: (self.frame.size.width-25) )



        let verticalContraint: [NSLayoutConstraint] = NSLayoutConstraint.constraints(withVisualFormat: "V:|-(>=200)-[toastView(==50)]-68-|", options: [.alignAllCenterX, .alignAllCenterY], metrics: nil, views: ["toastView": toastView])



        NSLayoutConstraint.activate([horizontalCenterContraint, widthContraint])

        NSLayoutConstraint.activate(verticalContraint)



        UIView.animate(withDuration: 0.5, delay: 0, options: .curveEaseIn, animations: {

            toastView.alpha = 1

        }, completion: nil)



        DispatchQueue.main.asyncAfter(deadline: .now() + .seconds(3), execute: {

            UIView.animate(withDuration: 0.5, delay: 0, options: .curveEaseIn, animations: {

                toastView.alpha = 0

            }, completion: { finished in

                toastView.removeFromSuperview()

            })

        })

    }

}

usage:

just call view.displayToast("Hello World") from UIViewController

There is a 3rd party library that supports customizable toast notification with single line of code. Here is a simple example of it:

import Toast_Swift



...



// basic usage

self.view.makeToast("This is a piece of toast")



// toast with a specific duration and position

self.view.makeToast("This is a piece of toast", duration: 3.0, position: .top)

Toast Swift library

Or else,

If you want to implement by your own. Use below code.

let toastLabel = UILabel(frame: CGRectMake(self.view.frame.size.width/2 - 150, self.view.frame.size.height-100, 300, 35))

                    toastLabel.backgroundColor = UIColor.blackColor()

                    toastLabel.textColor = UIColor.whiteColor()

                    toastLabel.textAlignment = NSTextAlignment.Center;

                    self.view.addSubview(toastLabel)

                    toastLabel.text = "hello man..."

                    toastLabel.alpha = 1.0

                    toastLabel.layer.cornerRadius = 10;

                    toastLabel.clipsToBounds  =  true

                    UIView.animateWithDuration(4.0, delay: 0.1, options: UIViewAnimationOptions.CurveEaseOut, animations: {



                        toastLabel.alpha = 0.0



                        })

This is best library I used for showing Toast in iOS apps same as android.

It also has pod support and pod name is pod 'Toast'

And implementation is so simple like

#import <UIView+Toast.h>

in your ViewController and then following line wherever you want to show it

[self.view makeToast:@"YOUR TOAST MESSAGE" duration:TOAST_TIMEOUT position:TOAST_CENTER];

Value for above keys are

#define TOAST_TOP @"CSToastPositionTop"

#define TOAST_CENTER @"CSToastPositionCenter"

#define TOAST_BOTTOM @"CSToastPositionBottom"

#define TOAST_TIMEOUT 2.0

there is no ThostView in iOS. we Can custom are use 3rd party libraries.

An attempt to make Suhit Pal's answer above Swift 4 like with a way to remove an existing Toast once a new appears

extension UIView {



    private static var toastView: UILabel? = nil



    func displayToast(message : String, duration: Double? = 3.0) -> Void {

        if UIView.toastView != nil {

            UIView.toastView!.removeFromSuperview()

        }

        UIView.toastView = UILabel()

        UIView.toastView!.backgroundColor = UIColor.black.withAlphaComponent(0.7)

        UIView.toastView!.textColor = UIColor.white

        UIView.toastView!.textAlignment = .center

        UIView.toastView!.font = UIFont(name: "Font-name", size: 17)

        UIView.toastView!.layer.masksToBounds = true

        UIView.toastView!.layer.cornerRadius = 25

        UIView.toastView!.text = message

        UIView.toastView!.numberOfLines = 0

        UIView.toastView!.alpha = 0

        UIView.toastView!.translatesAutoresizingMaskIntoConstraints = false



        let window = UIApplication.shared.delegate?.window!

        window?.addSubview(UIView.toastView!)



        let horizontalCenterContraint : NSLayoutConstraint = NSLayoutConstraint(item: UIView.toastView!, attribute: .centerX, relatedBy: .equal, toItem: window, attribute: .centerX, multiplier: 1, constant: 0)

        let widthContraint: NSLayoutConstraint = NSLayoutConstraint(item: UIView.toastView!, attribute: .width, relatedBy: .equal, toItem: nil, attribute: .width, multiplier: 1, constant: (self.frame.size.width-25) )

        let verticalContraint: [NSLayoutConstraint] = NSLayoutConstraint.constraints(withVisualFormat: "V:|-(>=200)-[loginView(==50)]-68-|", options: [.alignAllCenterX, .alignAllCenterY], metrics: nil, views: ["loginView": UIView.toastView!])



        NSLayoutConstraint.activate([horizontalCenterContraint, widthContraint])

        NSLayoutConstraint.activate(verticalContraint)



        UIView.animate(withDuration: 0.5, delay: 0, options: .curveEaseIn, animations: {

            UIView.toastView!.alpha = 1

        }, completion: nil)



        DispatchQueue.main.asyncAfter(deadline: .now() + duration!) {

            UIView.animate(withDuration: 0.5, delay: 0, options: .curveEaseIn, animations: {

                UIView.toastView!.alpha = 0

            }, completion: { (_) in

                UIView.toastView!.removeFromSuperview()

            })

        }

    }

}

Here is my latest version of this. It allows to cancel an existing toast by just pushing a new. It also allows to provide an optional "reverseColors" parameter, which writes white on black instead default black on white. The toast adapts to the text size with a little margin left and right.

extension UIView {



    private static var toastView: UILabel? = nil

    private static var toastViewCancelTask : DispatchWorkItem?



    func displayToast(message : String, duration: Double, reverseColors: Bool? = false) -> Void {

        if UIView.toastView != nil {

            UIView.toastView!.removeFromSuperview()

            UIView.toastViewCancelTask?.cancel()

        }





        UIView.toastView = UILabel()

        UIView.toastViewCancelTask = DispatchWorkItem {

            UIView.animate(withDuration: 0.5, delay: 0, options: .curveEaseIn, animations: {

                UIView.toastView!.alpha = 0

            }, completion: { (_) in

                UIView.toastView!.removeFromSuperview()

            })

        }



        let toastView = UIView.toastView!

        print(message)



        if reverseColors != nil && reverseColors! {

            toastView.backgroundColor = UIColor.black.withAlphaComponent(0.7)

            toastView.textColor = UIColor.white

        }

        else {

            toastView.backgroundColor = UIColor.white.withAlphaComponent(0.7)

            toastView.textColor = UIColor.black

        }

        toastView.textAlignment = .center

        toastView.font = UIFont.systemFont(ofSize: 17)

        toastView.layer.masksToBounds = true

        toastView.layer.cornerRadius = 12

        toastView.text = message

        toastView.numberOfLines = 0

        toastView.alpha = 0

        toastView.sizeToFit()

        toastView.translatesAutoresizingMaskIntoConstraints = false



        let width = toastView.frame.size.width +  100 > self.frame.size.width ? self.frame.size.width - 100 : toastView.frame.size.width + 100



        let window = UIApplication.shared.delegate?.window!

        window?.addSubview(toastView)



        let horizontalCenterContraint : NSLayoutConstraint = NSLayoutConstraint(item: toastView, attribute: .centerX, relatedBy: .equal, toItem: window, attribute: .centerX, multiplier: 1, constant: 0)

        let widthContraint: NSLayoutConstraint = NSLayoutConstraint(item: toastView, attribute: .width, relatedBy: .equal, toItem: nil, attribute: .width, multiplier: 1, constant: width )

        let verticalContraint: [NSLayoutConstraint] = NSLayoutConstraint.constraints(withVisualFormat: "V:|-(>=200)-[loginView(==50)]-30-|", options: [.alignAllCenterX, .alignAllCenterY], metrics: nil, views: ["loginView": toastView])



        NSLayoutConstraint.activate([horizontalCenterContraint, widthContraint])

        NSLayoutConstraint.activate(verticalContraint)



        UIView.animate(withDuration: 0.5, delay: 0, options: .curveEaseIn, animations: {

            toastView.alpha = 0.8

        }, completion: nil)



        DispatchQueue.main.asyncAfter(deadline: .now() + duration , execute: UIView.toastViewCancelTask!)

    }



}
