Problem with console apps

Using Swift
1

Hi All,

In Xcode 8.3 beta print() stopped outputting unterminated lines:
https://bugs.swift.org/browse/SR-3827

I've retested with recently released beta 2 and the issue is still present.
Could anyone from dev team take a look at this issue please?
I'm worried that it will make into release because it makes working
with interactive console apps impossible.

Regards,
Andrey

A follow-up:
flushing stdout works in console, but not in Xcode.
Neither setbuf(stdout, nil) nor fflush(stdout) helps, so it appears
this is an Xcode issue.

import Darwin

setbuf(stdout, nil)
while true
{
    print("A question.")
    print("Your answer: ", terminator: "") // not printed
    //fflush(stdout)
    
    sleep(1)
    print("")
}

Regards,
Andrey

In that case you should file bug report at http://bugreport.apple.com <Feedback Assistant.
The xcode-users mailing list hosted at http://lists.apple.com <http://lists.apple.com/&gt; is also a reasonable place to discuss Xcode issues (but not a substitute for a bug report.)
