Get nth character of a string in Swift programming language

Question

How can I get the nth character of a string? I tried bracket([]) accessor with no luck.

var string = \"Hello, world!\"

var firstChar = string[         


        

Answer 1

By now, subscript(_:) is unavailable. As well as we can't do this

str[0] 

with string.We have to provide "String.Index" But, how can we give our own index number in this way, instead we can use,

string[str.index(str.startIndex, offsetBy: 0)]
