Swift Arrays

In Swift, the three main collection types for storing multiple values are Array, Set, and Dictionary.

This page focuses on the basics of working with Swift Arrays, one of the most commonly used collection types in Swift development.

  • Inserting Elements with insert()
• Swift Arrays - Removing Elements
  • Removing by Index with remove()
  • Removing a Range with removeSubrange()
  • Removing the First Element with removeFirst()
  • Removing the Last Element with removeLast()
  • Removing All Elements with removeAll()
  • Removing Elements by Value with removeAll(where:)
• Swift Arrays - Count and Element Positions
  • Getting the Number of Elements with count
  • Checking if an Array is Empty with isEmpty
  • Finding Positions with firstIndex() and lastIndex()
  • Checking for an Element with contains()
• Swift Arrays - Sorting Elements
  • Sorting with sort()
  • Sorting Structs and Class Objects
