Remove nth character from string

Question

I have seen many methods for removing the last character from a string. Is there however a way to remove any old character based on its index?

Answer 1

Here is a safe Swift 4 implementation.

var s = "Hello, I must be going"
var n = 5
if let index = s.index(s.startIndex, offsetBy: n, limitedBy: s.endIndex) {
    s.remove(at: index)
    print(s) // prints "Hello I must be going"
} else {
    print("\(n) is out of range")
}
