How do I implement a hash table in Swift?

In Swift, implementing a hash table can be achieved using dictionaries, which provide key-value storage and utilize hashing to ensure efficient data retrieval. Below is an example of how to implement a simple hash table using Swift dictionaries.

// Creating a simple hash table var hashTable: [String: Int] = [:] // Inserting key-value pairs hashTable["One"] = 1 hashTable["Two"] = 2 hashTable["Three"] = 3 // Retrieving a value if let value = hashTable["Two"] { print("Value for key 'Two': \(value)") } // Removing a key-value pair hashTable["One"] = nil print("Hash Table after removing key 'One': \(hashTable)")
