Loop Control Statements

Loop control statements change execution from its normal sequence. When execution
leaves a scope, all automatic objects that were created in that scope are destroyed.

Swift supports the following control statements. Click the following links to check their
detail.

Control Statement Description

continue statement

This statement tells a loop to stop what it is doing and start

again at the beginning of the next iteration through the loop.

break statement Terminates the^ loop^ statement and transfers execution to

the statement immediately following the loop.

fallthrough

statement

The fallthrough statement simulates the behavior of swift

switch to C-style switch.

Swift – continue Statement

The continue statement in Swift tells a loop to stop what it is doing and start again at the
beginning of the next iteration through the loop.

For a for loop, the continue statement causes the conditional test and increments the
portions of the loop to execute. For while and do...while loops, the continue statement
causes the program control to pass to the conditional tests.
