Swiftpack.co - Package - sberrevoets/SDCAlertView


SDCAlertView started out as an alert that looked identical to UIAlertView, but had support for a custom content view. With the introduction of UIAlertController in iOS 8, the project was updated to the more modern API that UIAlertController brought.


  • ☑ Most UIAlertController functionality
  • ☑ Custom content views
  • ☑ Preventing controllers from dismissing when the user taps a button
  • ☑ Easy presentation/dismissal
  • ☑ Attributed title label, message label, and buttons
  • ☑ Appearance customization
  • ☑ Usable from Swift and Objective-C
  • ☑ Understandable button placement
  • ☑ UI tests
  • ☑ Custom alert behavior
  • ☑ CocoaPods/Carthage/Swift Package Manager support
  • ☐ Easy queueing of alerts


  • Swift 5.0
  • iOS 9 or higher



To install SDCAlertView using CocoaPods, integrate it in your existing Podfile, or create a new Podfile:

platform :ios, '9.0'

target 'MyApp' do
  pod 'SDCAlertView'

Then run pod install.


To install with Carthage, add the following line to your Cartfile:

github "sberrevoets/SDCAlertView"

Run carthage update and drag SDCAlertView.framework in the Build folder into your project.

Swift Package Manager

SPM does not yet support iOS, but SDCAlertView will be available there once it does.

Alerts vs. Action Sheets

SDCAlertController supports the presentation of action sheets, but there are some limitations and things to keep in mind when using action sheets:

  • It does not properly adapt on iPad. This is because iOS doesn't support UIModalPresentationStyle.Custom for adaptive presentations (such as when presenting an action sheet from a bar button item).
  • The new AlertBehaviors is, due to limitations in the Swift/Objective-C interop, not available when using SDCAlertController from Swift. This affects AlertControllerStyle.Alert as well.
  • When adding subviews to the custom content view, that view will replace the title and message labels.


SDCAlertView is written in Swift, but can be used in both Swift and Objective-C. Corresponding types in Objective-C have the same name they do in Swift, but with an SDC prefix.


let alert = AlertController(title: "Title", message: "This is a message", preferredStyle: .alert)
alert.addAction(AlertAction(title: "Cancel", style: .normal))
alert.addAction(AlertAction(title: "OK", style: .preferred))

// or use the convenience methods:

AlertController.alert(withTitle: "Title", message: "This is a message", actionTitle: "OK")
AlertController.sheet(withTitle: "Action sheet title", "Action sheet message", actions: ["OK", "Cancel"])

Custom Content Views

let spinner = UIActivityIndicatorView(activityIndicatorStyle: .gray)
spinner.translatesAutoresizingMaskIntoConstraints = false

let alert = AlertController(title: "Title", message: "Please wait...")

spinner.centerXAnchor.constraint(equalTo: alert.contentView.centerXAnchor).isActive = true
spinner.topAnchor.constraint(equalTo: alert.contentView.topAnchor).isActive = true
spinner.bottomAnchor.constraint(equalTo: alert.contentView.bottomAnchor).isActive = true


Dismissal Prevention

let alert = AlertController(title: "Title", message: "This is a message")
alert.addAction(AlertAction(title: "Dismiss", style: .preferred))
alert.addAction(AlertAction(title: "Don't dismiss", style: .normal))
alert.shouldDismissHandler = { $0.title == "Dismiss" }

Styling and Appearance

SDCAlertController is a normal view controller, so applying a tintColor to its view will color the buttons and any subviews you add to the contentView.

If you are looking for more customizations, create a subclass of AlertVisualStyle and use visualStyle on the AlertController instance. You can also create an instance of AlertVisualStyle and overwrite the attributes you need (this is mainly intended to be used from Objective-C). Note that after an alert has been presented, changing any of these settings is ignored.
