Chapter 13 : Swift Loops
Sometimes we need to execute a piece of code several time.
For example if need to print counting from 1,2….100 then instead of writing print statement 100 times we prefer to add a loop of for and print in a single line.
We have below loops statement to be used in swift
for-in : This loop is used for executing a set of statements for each item in a range , collection or progression.
while loop : This statement is used while a given condition is true. It tests the condition before executing the loop body.
repeat while loop : It is similar to while loop, the only difference is it test the condition at the end of the loop body.
All loops have its control statements as well, below are the control statement for loops
continue statement
Used to stop the loop and start again at the beginning of the next iteration in the loop
break statement
Used to terminate the loop statement
fall through statement
Used to simulates the behaviour of swift4 to C-style switch
