What does the program print?

SWIFT

var count = 0
repeat {
    count += 1
} while count > 5
print(count)

Expecting 0: treating repeat-while like while. repeat runs the body first and checks the condition after it, so the body always runs at least once.
Expecting 6: reading the loop as "repeat until count > 5". It repeats while the condition is true, and here it is false after the first pass.

What does the program print if the loop is rewritten as while count > 5 { count += 1 }?
When is repeat-while a better fit than while?
