add a key-value pair to a map in swift

To add a key-value pair to a Swift Dictionary (also known as a map), you can use the insert(_:forKey:) method. Here's an example:

main.swift
var myMap = [String: Any]()
myMap.insert("hello", forKey: "greeting")
70 chars
3 lines

In this example, a Dictionary is created with a String type as the key and an Any type as the value. The insert(_:forKey:) method is then used to add a key-value pair to the dictionary. The key "greeting" is associated with the value "hello".
