Introduction
I have used Swift for windows 1.9 for debugging purpose. But you can use any Swift programming language compiler as per your availability.
Write a Swift program to insert a given string to another given string where the second string will be in the middle of the first string
func insert_string(_ str1: String, _ str2: String) -> String {
var current_index = str1.startIndex
let char1: Character = str1[current_index]
var result = str1
while char1 == str1[current_index] {
current_index = str1.index(after: current_index)
}
result.insert(contentsOf: str2.characters, at: current_index)
return result
}
print(insert_string("<>", "Swift"))
print(insert_string("<>>", "Swift"))
print(insert_string("[]", "Swift"))Result
