Crash when tapping into UITextView in keyboard extension

I created a new iOS app with a keyboard extension. I added a UITextView to it, but when I tap on it, it crashes somewhere in outside of my code. This is pretty much the keyboard extension template with the UITextView added:

(In KeyboardViewController):


        super.viewDidLoad()

        

        // Perform custom UI setup here

        self.nextKeyboardButton = UIButton(type: .system)

        

        self.nextKeyboardButton.setTitle(NSLocalizedString("Next Keyboard", comment: "Title for 'Next Keyboard' button"), for: [])

        self.nextKeyboardButton.sizeToFit()

        self.nextKeyboardButton.translatesAutoresizingMaskIntoConstraints = false

        

        self.nextKeyboardButton.addTarget(self, action: #selector(handleInputModeList(from:with:)), for: .allTouchEvents)

                self.view.addSubview(self.nextKeyboardButton)

        



        self.nextKeyboardButton.leftAnchor.constraint(equalTo: self.view.leftAnchor).isActive = true

        self.nextKeyboardButton.bottomAnchor.constraint(equalTo: self.view.bottomAnchor).isActive = true

        

        self.textView = UITextView(frame: .zero)

        guard let textView = self.textView else { return }

        

        textView.attributedText = NSAttributedString(string: "test keyboard")

        textView.translatesAutoresizingMaskIntoConstraints = false

        textView.layer.borderColor = UIColor.blue.cgColor

        textView.layer.borderWidth = 2

        

        view.addSubview(textView)

        

        NSLayoutConstraint.activate([

            textView.topAnchor.constraint(equalTo: view.topAnchor, constant: 10),

            textView.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: 10),

            textView.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 10),

            textView.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: 10),

        ])

    }

What’s interesting is that in my actual app, the same code works as long as Full Access is granted for the keyboard.

From what I understand, UITextViews should work even if Full Access isn’t granted.

Has anyone had any experience with putting a UITextView into a keyboard extension not running with Ful Access?
