Swift Array suffix()

var numbers = [2, 4, 6, 8, 10, 11, 12, 13]

// return last 3 elements 
print(numbers.suffix(3))

// Output: [ 11, 12, 13 ]

suffix() Syntax

The syntax of the array suffix() method is:

array.suffix(number: Int)

Here, array is an object of the Array class.

suffix() Parameters

The suffix() method takes a single parameter:

• number - number of elements to return from array

Note: number must be greater than or equal to 0.

suffix() Return Value

• returns the specified number of elements from the last element.

Example 1: Swift Array suffix()

var languages = ["Swift", "C", "Java", "Objective-C", "Kotlin"]

// return last 3 elements 
print(languages.suffix(3))

var prime = [9, 12, 52, 43]

// return last 2 elements 
print(prime.suffix(2))

Output

["Java", "Objective-C", "Kotlin"]
[52, 43]

In the above example,

• languages.suffix(3) - returns the last 3 elements of the languages array
• prime.suffix(2) - returns the last 2 elements of the prime array

Example 2: Return Empty And Original Array using suffix()

var names = ["Greg", "Ludovico", "Ben", "Cartman"]

// return empty array 
print(names.suffix(0))

// return original array 
print(names.suffix(4))

Output

[]
["Greg", "Ludovico", "Ben", "Cartman"]

Here,

• names.suffix(0) - since we have passed 0, the method returns the empty array
• names.suffix(4) - since the number of elements to return (4) is equal to the number of elements in the array, the method returns the original array

Note: Even if the number of elements to return is greater than the number of elements in the array, the method will return the original array.
