Swift Set sorted()

var numbers: Set = [1, 3, 8, 5, 2]

// sort the numbers set
var result = numbers.sorted()

print(result)

// Output: [1, 2, 3, 5, 8]

sorted() Syntax

The syntax of the set sorted() method is:

set.sorted(by: operator)

Here, set is an object of the Set class.

sorted() Parameters

The sorted() method can take one parameter:

• operator (optional) - If we pass greater-than operator >, the set is reversed (or set in descending order)

sorted() Return Value

The sorted() method returns a sorted array.

Example 1: Swift Set sorted()

// set of strings
var names: Set = ["Adam", "Jeffrey", "Fabiano", "Danil", "Ben"]

// sort the names set
var result1 = names.sorted()

print(result1)

// set of integers
var priceList: Set = [1000, 50, 2, 7, 14]

// sort the priceList set
var result2 = priceList.sorted()

print(result2)

Output

["Adam", "Ben", "Danil", "Fabiano", "Jeffrey"]
[2, 7, 14, 50, 1000]

Here, we can see that the names set is sorted in ascending order of the string. For example, "Adam" comes before "Danil" because "A" comes before "D".

Similarly, the priceList set is set in ascending order.

Example 2: Sort in Descending Order

// set of strings
var names = ["Adam", "Jeffrey", "Fabiano", "Danil", "Ben"]

// sort the names set
names.sorted(by: >)

print(names)

// set of integers
var priceList = [1000, 50, 2, 7, 14]

// sort the priceList set
priceList.sorted(by: >)

print(priceList)

Output

["Jeffrey", "Fabiano", "Danil", "Ben", "Adam"]
[1000, 50, 14, 7, 2]

Here, to sort the elements in descending order, we have passed the > operator to the sorted() method
