Sorry, my example should have been the other way around:
var data: NSData!
for 1...5 {
data = self.loadSomeData()
if data != nil {
break // *this* can't be done with .forEach
}
/// Try again in next iteration
}
if data == nil {
return
}
/// Process data.
But yeah, it can be written the other way around to avoid break.
