Sample Solution:

Swift Code:

import Foundation

func fix_Start(_ input: String) -> Bool {
    var newInput = input
    let startIndex = newInput.startIndex
    let first_char = newInput.remove(at: startIndex)
    
    if newInput.hasPrefix("ix") == true 
    {
        newInput.characters.removeFirst(3)
        newInput.insert(first_char, at: startIndex)
        return true
    } 
    else
    {
        return false
    }
}


print(fix_Start("fix gold"))
print(fix_Start("six gold"))
print(fix_Start("1ix gold"))
print(fix_Start("gold"))
print(fix_Start("fax gold"))

Sample Output:

true
true
