Failed to set (titleText) user defined inspected property - custom-controls

Question

I have a UIViewController, "MainViewController"-
class MainViewController: UIViewController {
#IBOutlet weak var segmentControl: UISegmentedControl!
#IBOutlet weak var userNameTextField: UITextField!
#IBOutlet weak var passwordTextField: UITextField!
#IBOutlet weak var controlButton: RoundedCornerButton!
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func switchBetweenSignInAndRegisterOption(_ sender: UISegmentedControl) {
if sender.selectedSegmentIndex == 0{
self.controlButton.text = "Sign In"
}
else{
self.controlButton.text = "Register"
}
}
}
The action method- switchBetweenSignInAndRegisterOption(_:) attached to the segmentControl object and when its selectedSegmentIndex changes, the text property of my RoundedCornerButton is updated. The following is the code for RoundedCornerButton-
class RoundedCornerButton: UIButton {
var text: String = "Sign In"{
didSet{
setNeedsLayout()
}
}
override func layoutSubviews() {
super.layoutSubviews()
self.layer.borderWidth = 2.0
self.layer.cornerRadius = (self.bounds.size.width * 0.025)
self.layer.borderColor = UIColor.green.cgColor
self.setTitle(text, for: .normal)
self.titleLabel?.minimumScaleFactor = 0.50
}
}
It works in terms of functionality but it shows the following error in the console. I don't understand what might have gone wrong.
[ProjectName][12943:1296641] Failed to set (titleText) user defined inspected property on ([ProjectName].RoundedCornerButton):
[<[ProjectName].RoundedCornerButton 0x7f8a13d0bd90> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key titleText.
Any help would be greatly appreciated.

Answer 1

I found the issue though I have no idea, how it stayed in my storyboard because I removed the #IBInspectable from my CustomButton's code.
When I searched and couldn't find the titleText anywhere in my code and even in the storyboard user interface, I went to the source code of my storyboard by right clicking on it and select the source code option. To my utter surprise, there was this following code snippet-
<userDefinedRuntimeAttributes>
<userDefinedRuntimeAttribute type="string" keyPath="titleText" value="Register"/>
</userDefinedRuntimeAttributes>
Apparently even though I removed the #IBInspectable from my code, it stayed in my storyboard. I removed this part and now it works fine.
