Sample Solution:

Swift Code:

func new_string(_ input: String) -> String {
    var str1 = ""
    let chars = input.characters
    
    for (index, char) in chars.enumerated() {
        if index % 2 == 0 {
            str1.append(char)
        }
    }
    
    return str1
}
print(new_string("Python"))
print(new_string("Swift"))
print(new_string("Ab"))

Sample Output:

Pto
Sit
A
