Swift Continue Statement

The continue statement is a control statement that is used to skip the current iteration of a loop and move on to the next one. It is commonly used in loops to skip over certain elements or iterations based on a specific condition.

Syntax

The syntax of the continue statement in Swift is as follows:

continue

Example

Here is an example code snippet showing how to use the continue statement to skip over certain elements in a loop:

let numbers = [1, 2, 3, 4, 5]

for number in numbers {
    if number == 3 {
        continue
    }
    print(number)
}

Output

The above code will output the following:

1
2
4
5

As you can see, the number 3 has been skipped over due to the use of the continue statement.

Explanation

In the above example, we have an array of integers called numbers which we are iterating over using a for-in loop. Within the loop, we check if the current number is equal to 3 using an if statement. If the condition is true, the continue statement is used to skip over the current iteration and move on to the next one. If the condition is false, the print statement is executed and the current number is outputted to the console.

Use

The continue statement can be used in a variety of scenarios where you want to skip over certain elements or iterations of a loop based on a specific condition. It can be particularly useful when working with large data sets or complex algorithms where you need to process data in a specific way.

Important Points

• The continue statement is used to skip over the current iteration of a loop
• It can be used within any loop construct in Swift, including for, while, and repeat-while loops
• The continue statement is commonly used to skip over certain elements or iterations based on a specific condition
• Using continue can help to simplify your code and make it more efficient

Summary

The continue statement is a useful control statement in Swift that allows you to skip over certain elements or iterations in a loop based on a specific condition. It can be used to simplify your code and make it more efficient, particularly when working with large data sets or complex algorithms.
