How do I split a TextField into characters?

Question

enter image description hereSo basically, I want to put the word(s) inputted into a TextField into an array, but also split the word(s) up into separate characters so that each character of the word(s) has its one place in the array.

For Example, if someone inputted "monkey" into the TextField, it would be put into an array like this

inputtedWord = ["m","o","n","k","e","y"]

This is what I have for the TextField:
@State private var normalText: String = ""

TextField("Input the word you want to be cipher.",
   text: $normalText)
   .padding(.all)
       Text("\(normalText)")
