Button text shrinks when the text is changed - swift

Question

Ones I change the text in button it's getting stink to font size of ~18 even though initial font size is 55. Button is not custom. It has System font.
button.setTitle("Some button text", for: .normal)
I tried manually change font size in code but it doesn't help
button.titleLabel?.font = UIFont.systemFont(ofSize: 55)
I also tried to change the name through configuration function, but there is no font size and it shrinks anyway.
`
button.configuration = paperButtonConfiguration()
func buttonConfiguration() -> UIButton.Configuration {
var config: UIButton.Configuration = .plain()
config.title = "Some button text"
//Should probably be something like this but it doesn't work
//config.font = UIFont.systemFont(ofSize: 55)
return config
}
`
While I was writing this question I kind of solve this, but not completely. If I change the button style from "plain" to "default" it works, but some weird animation of fading and appearance occurs.
How could I do this with "plain"?

UIButton has four type are Plain,Grain,Tinted,Filled .When you create a button in storyboard , button type automatically set with Plain that means new UIButton configurations is on. If you want to old behaviour , you must set style plain to default.
Or , If you want one of the style above . You need to set font like
button.titleTextAttributesTransformer = UIConfigurationTextAttributesTransformer { incoming in
var outgoing = incoming
outgoing.font = UIFont.systemFont(ofSize: 50)
return outgoing
}
