Swift Array max()

max() Syntax

The syntax of the array max() method is:

array.max()

Here, array is an object of the Array class.

max() Parameters

The max() method doesn't take any parameters.

max() Return Values

• returns the maximum element from the array

Note: The max() method returns an optional value, so we need to unwrap it. There are different techniques to unwrap optionals. To learn more about optionals, visit Swift Optionals.

Example 1: Swift Array max()

Output

Optional(10)
9.6

In the above example, we have created two arrays named integers and decimals. Notice the following:

• integers.max() - since we have not unwrapped the optional, the method returns Optional(10)

• decimals.max()! - since we have used ! to force unwrap the optional, the method returns 9.6.

Example 2: Find Largest String Using max()

Output

Swift

Here, the elements in the languages array are strings, so the max() method returns the largest element (alphabetically).
