Human readable tag/id for a View in iOS - ios

Question

Let's say I have created a UI with some views using an interface builder (not in code, so not programmatically).
How can I assign human readable ids / tags to these views, so that I could reference them in code?
I know that I can assign an integer tag to a view using attribute inspector and then make a dictionary (or enum) to store the mapping of tags to the views. However, this is an error-prone method which also scales really badly (imaging assigning integer tags to hundred of views in a complex app...).
Is there a better solution for this problem? Is there a way to directly assign a human readable tag / id to a view, like "resumeButton"?
UPDATE:
Here is an example scenario of what I want to achieve:
UI with five different buttons; the buttons have image and no title
all five buttons are connected to the same IBAction in code
in IBAction I have a switch statement, so that depending on which button is clicked, different versions of code are executed
UPDATE 2:
SOLUTION
I ended up implementing a simple custom view:
#IBDesignable
class CustomButton: UIButton {
#IBInspectable var stringTag: String = defaultID
}
This way I can see an additional property stringTag in Interface Builder and can simply add a value to it directly in Interface Builder.

Answer 1

You could create an extension property on UIView to store an identifier string. If you made that extension property IBInspectable, you could set and view it from the storyboard directly.
More detail on setting up such a property in this answer:

The built-in tag property for UIView is just an integer, so it isn't very descriptive for humans who read it.

Answer 2

From what you're describing sounds to me that you are looking for an: Outlets

Answer 3

You are right about tags. Every connection with Interface Builder should be handled using IBAction and IBOutlet.
Since you say that every button has a different action, the simplest solution is to create a separate IBAction for each of them:
#IBAction private func onResumeButtonTapped() {
...
}
#IBAction private func onPauseButtonTapped() {
...
}
If you, for some reason, want to keep them connected to one function, you can use outlets:
#IBOutlet private var resumeButton: UIButton!
#IBOutlet private var pauseButton: UIButton!
#IBAction private func onButtonPressed(_ sender: UIButton) {
switch sender {
case resumeButton:
...
case pauseButton:
...
default:
break
}
}
