Until in Objective-C

In Objective-C, until is not a keyword on its own. However, it can be used as part of an if statement with the while condition. Here's an example:

int count = 0;
do {
    count++;
    NSLog(@"Count is now %d", count);
} while (count < 5);

This will output:

Count is now 1
Count is now 2
Count is now 3
Count is now 4
Count is now 5

The do-while loop will execute the statement(s) inside the block at least once, and will continue to loop while the condition inside the while clause is true.

So in this example, the loop will execute until count is no longer less than 5. The until condition is effectively the same as saying "while the condition is not true."
