What is the order of keyboard display and input start delete in Swift5TextView?

What is troubling me is the order in which modules are called regarding keystrokes.
In TextView input,

(1) @objc showKeyboard
(2)textViewdidbeginEditing

is referred to in the order shown in .

I would like to check the input area in (2) and specify a numeric keyboard or mail keyboard, but the showKeyboard will be called first, so it will not work properly.
TextView is configured as a custom cell, so it has the following modules:
Is there any way to change the order of being called?
By the way, I remember that using textField was the opposite of the above.

import UIKit

protocol Cell_MultiLineDelegate{
    functextViewDidEndEditing(textCell:Cell_MultiLine, value:NSString) - >()
    functextViewDidBeginEditing(textCell:Cell_MultiLine, value:NSString) - >()
}

class Cell_MultiLine:UICollectionViewCell, UITextViewDelegate{

    @IBOutlet weak var leading —NSLayoutConstraint!
    @IBOutlet weak var training:NSLayoutConstraint!
    @IBOutlet peak:NSLayoutConstraint!
    @IBOutlet weak varbottom:NSLayoutConstraint!
    @IBOutlet weak var backView: UIView!
    @IBOutlet weak var beforeView: UIView!
    @IBOutlet weak var contents:UITextView!
    //    @IBOutlet weak var contents: UITextField!
    
    varcurrentIndexPath —IndexPath!
    vardelegate —Cell_MultiLineDelegate!=nil
    var currentComment: String!
    var fixedComment: String!

    override funcawakeFromNib(){
        super.awakeFromNib()
        // initialization code
        self.contents.delegate=self        
    }
    
    functextView(_textView:UITextView, shouldChangeTextInrange:NSRange, replacementTexttext:String) - >Bool{
        if currentIndexPath.row>6 {// Except for the bottom multi-line input area = Special note area
            if text == "\n" {
                textView.resignFirstResponder()
                self.delegate.textViewDidEndEditing (textCell:self, value:contents.text!as NSSstring)
                return false
            }
        }
        return true
    }

/*
    internal func textFieldShouldReturn(_textField:UITextField) - >Bool{
        textField.resignFirstResponder()
        return true
    }
*/
    internal func textViewDidEndEditing(_textView:UITextView){
        self.delegate.textViewDidEndEditing (textCell:self, value:contents.text!as NSSstring)
    }

    internal func textViewDidBeginEditing(_textView:UITextView){
        self.delegate.textViewDidBeginEditing (textCell:self, value:contents.text!as NSSstring)
    }

}
// Vertical Centralization
extension UITextView {
    funcenterVerticalText(){
        self.textAlignment=.left
        letfitSize = CGSize (width: bound.width, height: CGFloat.greatestFiniteMagnitude)
        let size = sizeThatFits(fitSize)
        let calculate=(bound.size.height-size.height*zoomScale)/2
        let offset=max(1,calculate)
        contentOffset.y=-offset
    }
}

textViewDidBeginEditing of UITextViewDelegate is apparently running after the keyboard is displayed.So, why don't you use textViewShouldBeginEditing?

 functextViewShouldBeginEditing(_textView:UITextView)->Bool{
    textView.keyboardType=.decimalPad
    return true
}

After checking here, I was able to see the numeric keypad with this Delete.
I don't think you're worried about such a simple thing, but just for your information.
