find the keys of a map in swift

To find the keys of a Swift dictionary, you can use the keys property. Here's an example:

main.swift
let myDictionary = ["key1": "value1", "key2": "value2", "key3": "value3"]
let keys = myDictionary.keys
print(keys) // Output: ["key2", "key3", "key1"] (the order of keys may vary)
180 chars
4 lines

In this example, myDictionary.keys returns a LazyMapCollection object that contains the keys of the dictionary. You can then use this object to iterate over the keys or access them directly.
