Kotlin Cannot Inflate Layout - android-studio

Question

I am building an application that has a GridView that contains a dynamic amount of CardViews. I am having issues accessing the TextView elements in the individual items layout from the custom adapter that I am creating.
tvCastleName and tvShieldTime are unresolved references, and the application will not compile.
main.xml

You must be getting Unresolved Reference as the method (Kotlin Synthetics) you are using to access view is now deprecated. You can use ViewBinding to access your views.
You've to make a few changes to your getItem method, to make it work with ViewBinding
override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {
val nameList = this.nameList[position]
val itemsBinding = ItemsBinding.inflate(LayoutInflater.from(parent.context), parent, false)
itemsBinding.tvCastleName.text = nameList.name!!
itemsBinding.tvShieldTime.text = "15:00"
return itemsBinding.root
}
