How to use search in icarousel current index item?

Question

Hey all I am just wondering how can I use a search bar to reload data in carousel item without reloading all other items?

below is the code for the carousel:

to Note the concerned one is if == "Languages"

lazy var car:iCarousel = {
        let view = iCarousel()
        view.frame = CGRect(x:0, y:Int(CGFloat(Double(Int(Float(bounds.size.height*0.05))) + globW  )) , width: Int(Float(bounds.size.width)*0.85), height: Int(Float(bounds.size.height)*0.75))
//        view.type = .coverFlow
        view.type = .wheel
        view.isVertical = true
        view.bounces = true
        view.decelerationRate = 0.0
        view.clipsToBounds=true
//        view.isScrollEnabled = false
//        view.backgroundColor = .red

        return view
    }()

below is the concerned case for the carousel item:

case "C":
                
                let titleV:UILabel!
                let titleOption:NSMutableAttributedString!
                let fSAttr = [ NSAttributedString.Key.font: UIFont(name: "Helvetica", size: bounds.size.width*0.04)!,
                    NSAttributedString.Key.foregroundColor : UIColor.white,
                ]

                titleOption = NSMutableAttributedString(string:currentField[index].placeholder!, attributes: fSAttr)
                let widthFS = titleOption.width(containerHeight: v.bounds.width*0.5)
        
                img.frame=CGRect(x: Double(v.bounds.width)*0.5-Double(bounds.size.width)*0.05, y: Double(v.bounds.height)*0.2, width:Double(bounds.size.width)*0.1, height: Double(bounds.size.width)*0.1)

                v.addSubview(img)
                
                titleV = UILabel(frame: CGRect(x:Int((v.bounds.width - widthFS)*0.5)  , y: Int(-v.bounds.height*0.02), width: Int(Float(0.449*bounds.size.height)), height: Int(Float(0.567*bounds.size.height))))
                titleV.backgroundColor = .clear
                titleV.attributedText = titleOption
//                v.bounds.height*0.33
//                titleV.isEditable = false
                v.addSubview(titleV)
                currentCarView = v
                if currentField[index].id == "Languages"{

                }

Here is the editfunction:

@objc func editSearch(_ sender:UITextField){
      
        DispatchQueue.main.async { [self] in
            sender.text = sender.text!
            
            currentCarView.backgroundColor = .red
     car.reloadData()
            car.currentItemView?.reloadInputViews()
        }
 
  
    }

thank you all for your item, please. do suggest for better ways
