What type of data is a dictionary where keys are strings and values can be of different types?

In iOS (Swift), a dictionary where keys are strings and values can be of different types is usually represented by the type Dictionary<String, Any>.

Here:

• String is the type of the keys.
• Any is a universal type that can contain values of any type.

Example:

var dict: [String: Any] = [
    "name": "Ivan",
    "age": 30,
    "isMember": true
]

print(dict["name"] as? String ?? "")  // Ivan

Using Any allows storing values of different types in the dictionary but requires type casting when retrieving.
