Trigger PickerView from UILabel to have it Modally Appear From the Bottom the Screen and not Hide/Unhide It

Question

I have label with a gesture recognizer inside a collectionView cell. When the user touches the label I want a pickerView to appear similar to how it would appear when a pickerView is attached to a textField.

I tried myLabel.inputView = pickerView

I got this error below.

Cannot assign to property: 'inputView' is a get-only property

I came across some threads where people were hiding and unhiding the pickerView instead of it popping up and lowering like a it does from a textField but no one explained why they hid/unhid it.

How can I trigger a PickerView from a UILabel?

It should be noted that I don't want to hide/unhide it like the other answers that I read.

class MyCell: UICollectionViewCell {

    lazy var pickerView = UIPickerView()

    let myLabel: UILabel = {
        let label = UILabel()
        label.translatesAutoresizingMaskIntoConstraints = false
        label.isUserInteractionEnabled = true
        return label
    }()

    override init(frame: CGRect) {
        super.init(frame: frame)

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(triggerPickerView))
        myLabel.addGestureRecognizer(tapGesture)

    }

    @objc func triggerPickerView() {
       print("triggerPickerView")
    }
}

I found the answer.

In the comments @AshlyMills said the reason I can't trigger the picker view from a UILabel is because: "It's not possible because inputView is a get only property on UIResponder"

My workaround was to a use a UITextField and just make it clear. I added the pickerView as an inputView to the textFiled. I laid it directly over the label and by pressing it the pickerView appears modally from the bottom and the label is still visible. I removed the gesture recognizer because it wasn't necessary.

class MyCell: UICollectionViewCell {

    lazy var pickerView = UIPickerView()

    let myLabel: UILabel = {
        let label = UILabel()
        label.translatesAutoresizingMaskIntoConstraints = false
        label.isUserInteractionEnabled = true
        return label
    }()

    let clearTextField: UITextField = {
        let textField = UITextField()
        textField.translatesAutoresizingMaskIntoConstraints = false
        textField.backgroundColor = .clear
        return textField
     }()

    override init(frame: CGRect) {
        super.init(frame: frame)


        addSubview(clearTextField)

        clearTextField.topAnchor.constraint(equalTo: myLabel.topAnchor).isActive = true
        clearTextField.leftAnchor.constraint(equalTo: myLabel.leftAnchor).isActive = true
        clearTextField.rightAnchor.constraint(equalTo: myLabel.rightAnchor).isActive = true
        clearTextField.bottomAnchor.constraint(equalTo: myLabel.bottomAnchor).isActive = true

        clearTextField.inputView = pickerView
    }
}
