Small Summary about the repository and its purpose

About:

Go into more detail about the repository and its purpose

Features:

Integer From String

If a variable read from the console is an integer, then return true:

func checkIfStringContainsInteger(with string: String) -> Bool {
  if let string = Int(string) {
    return true
  }
  
  return false
}

if let readLine = readLine() {
  print(checkIfStringContainsInteger(with: readLine))
}

But we can improve this code by extending String to get self as the String type presented

extension String {
  func checkIfStringContainsInteger() -> Bool {
    if let self = Int(self) { return true }
    
    return false
  }
}

if let readLine = readLine() {
  print(checkIfStringContainsInteger(with: readLine))
}

Write a small conclusion for your repository
