Swift â&#x20AC;&#x201C; 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. 49
