How to access button data?

Am using Xode 10.0 for a ios app and need to access the button title for it's current state, analyze and/or change it.

Am using IBAction func "button name" (_sender:AnyObject) { code }

I have tried UITextview's "name" .text = title but does show up in the textview.

When trying to print the contents of title it yields nil although there is data in the button title and appears on the button view.

Am using the simulator for iphone xr and when using "name" .text = "AB" it will show in textview on simulator button press.

Thanks...Charlie
