Can we use a class (.self) as the target in addTarget(_:action:for:) for static event handlers?

I am building a centralized event handling system for UIKit controls and gesture recognizers. My current approach registers events using static methods inside a handler class, like this:

internal class TWOSInternalCommonEventKerneliOS {

    internal static func RegisterTouchUpInside(_ pWidget: UIControl) -> Void {
        pWidget.addTarget(
            TWOSInternalCommonEventKerneliOS.self,
            action: #selector(TWOSInternalCommonEventKerneliOS.WidgetTouchUpInsideListener(_:)),
            for: .touchUpInside
        )
    }

    @objc
    internal static func WidgetTouchUpInsideListener(_ pWidget: UIView) -> Void {
        print("WidgetTouchUpInside")
    }
}

This works in my testing because the methods are marked @objc and static, but I couldn’t find Apple documentation explicitly confirming whether using ClassName.self (instead of an object instance) is officially supported.

Questions:

Is this approach (passing ClassName.self as the target) recommended or officially supported by UIKit?

If not, what is the safer alternative to achieve a similar pattern, where event registration can remain in static methods but still follow UIKit conventions?

Would using a shared singleton instance as the target (e.g., TWOSInternalCommonEventKerneliOS.shared) be the correct approach, or is there a better pattern?

Looking for official guidance to avoid undefined behavior in production.
