Swift Programming Language

1. Swift provides three primary collection types: Arrays, Sets, and Dictionaries. Match the collection type on the left to the way the collection is organized on the right.

Array a) Unordered collection of key- value pairs b) Unordered collection c) Ordered collection

Dictionary a) Unordered collection of key- value pairs b) Unordered collection c) Ordered collection

Set a) Unordered collection of key- value pairs b) Unordered collection c) Ordered collection

3.

If you assign an array, a set, or a dictionary to a constant, that collection is which of the following?

immutable (its size and contents cannot be changed)

mutable (its size and contents can be changed)

4.

You can create an array in Swift by adding two arrays together. For example, if there are two arrays of names called names1 and name2, the following is allowed:

var allNames = names1 + names2

True

False
