First of all well done a very good and complete written wrapper for UIAlert Controller. So my point is that when a user call action sheet on iPhone or iPad so your code should automattically set popover if device is a iPad so there is no need of user decision.

Some minor APIs were renamed in Swift 4.2, current version does not compile/run on latest Xcode/Swift. I can make a pull request if you do not have time but the changes are very minor

I have implemented the basic Swift Package Manager support and updated the project files to use the latest Xcode standard.

Thanks for your work on this library!

Cannot convert value of type '(_) -> UIViewController?' to expected argument type 'Alertift.Alert.Handler?' (aka 'Optional<(UIAlertAction, Int, Optional<Array<UITextField>>) -> ()>')

Here is the log when open:

Warning: Attempt to present <Alertift.InnerAlertController: 0x7fd4f816d000> on <UINavigationController: 0x7fd4f8012a00> whose view is not in the window hierarchy!

Alertift can only add action one by one for now. It will make it possible to add actions at once.

Alertift.actionSheet(message: "Which food do you like?")
   .popover(sourceView: self.view, sourceRect: button.frame)
   .actions([.default("🍣"), .default("🍎"), .default("🍖"), .default("🍅")]) { action, index in
       if action.style == .cancel {
           return
       }
       Alertift.alert(message: "\(index). \(action.title!)")
           .action(.default("OK"))
           .show()
    }
    .show(on: self)

I just implemented ShortHandler. By using this ShortHandler, it is possible to avoid writing `(_, _, _) in closure if you don't use closure arguments.

Before

Alertift.alert(title: "Sample 2",message: "Do you like 🍣?")
    .action(.default("Yes"), isPreferred: true) { _, _, _ in
        Alertift.alert(message: "🍣🍣🍣")
            .action(.default("Close"))
            .show()
    }
    .action(.cancel("No")) { _, _, _ in
        Alertift.alert(message: "😂😂😂")
            .action(.destructive("Close"))
            .show()
    }
    .show()

After

Alertift.alert(title: "Sample 2",message: "Do you like 🍣?")
    .action(.default("Yes"), isPreferred: true) {
        Alertift.alert(message: "🍣🍣🍣")
            .action(.default("Close"))
            .show()
    }
    .action(.cancel("No")) {
        Alertift.alert(message: "😂😂😂")
            .action(.destructive("Close"))
            .show()
    }
    .show()

Diff

+     .action(.default("Yes"), isPreferred: true) {
-     .action(.default("Yes"), isPreferred: true) { _, _, _ in

hello. I found some problem with Swift 4.2 and Xcode 10, Legacy Build System(under File > Workspace Settings... )

I use alertift 4.0 with cocoapds, It occurs syntax error at InnerAlertController.swift, Lines 162: source here

func registerTextFieldObserver(_ textField: UITextField) {
        NotificationCenter.default.addObserver(
            self,
            selector: #selector(self.textFieldDidChange(_:)),
            name: UITextField.textDidChangeNotification, object: textField
        )
    }

Xcode guides to fix it like this.

    func registerTextFieldObserver(_ textField: UITextField) {
        NotificationCenter.default.addObserver(
            self,
            selector: #selector(self.textFieldDidChange(_:)),
            name: Notification.Name.UITextFieldTextDidChange, object: textField
        )
    }

I fork and clone this repo, and load demo app - I can't reappearance that error.

How can i add icon to Action button and set the text alignment to left on Action Button.

For reference, you can see the whatsApp. I need exactly to WhatsApp action sheet.

Using the pod creates a warning with the current Xcode, when creating apps for iOS 14 (and newer, in the future). Maybe remove the default value for viewController in the show method (AlertType.swift, line 154)?
