How can you remove an element from within a dictionary?

In iOS, to remove an element from a dictionary, you can use the removeValue(forKey:) method or assign nil to the value for a key.

Example:

var dict = ["key1": "value1", "key2": "value2"]
dict.removeValue(forKey: "key1") // Removes the element with key "key1"

// Or
// dict["key1"] = nil

After this, the element with the specified key will be removed from the dictionary.
