  • A byte buffer in memory.

    Declaration

    class Data
  • A heterogeneous dictionary which stores associations between keys of the different types and values of the different types in a collection with no defined ordering. Each value is associated with a unique key, which acts as an identifier for that value within the dictionary. Unlike items in an array, items in a dictionary do not have a specified order. You use a dictionary when you need to look up values based on their identifier, in much the same way that a real-world dictionary is used to look up the definition for a particular word.

  • A string is a series of characters, such as "Hey mom, there's something in the backroom hope it's not the creatures from above." or "You used to read me stories as if my dreams were boring.". Swift strings are represented by the String type. The contents of a String can be accessed in various ways, including as a collection of Character values.
