Swift Array joined()

joined() Syntax

The syntax of the joined() method is:

array.joined(separator: delimiter)

Here, array is an object of the Array class.

joined() Parameter

The joined() method takes one parameter:

• delimiter (optional) - the separator to join the elements

Note: If we call joined() without any parameter, the elements are joined without any separator.

joined() Return Value

• returns a string with all the array elements joined by a separator

Example: Swift joined()

Output

DellHPApple
Dell HP Apple
Dell, HP, Apple

Here, we can see that the joined() method converts all the array elements into a string and separates each element by the specified separator.
