Try int main(void) {, i.e.: #include<stdio.h> int main(void) { printf("Hello World"); return 0; }

Speak to the Discord people.

I don't think so. The idea is that you've attached an external keyboard and are obviously going to use that for typing, so why would you want part of the screen to be taken up with a keyboard you aren't going to use?

Yes, this is really clear.

Your question is more of a support one, so I'd suggest you ask it over at the Apple Support Forums. Thanks.

What was the error? Saying you got an error, then not actually telling us what the error is, is not particularly useful. Is that version of the app actually compatible with the new macOS beta? You should get in touch with the MySQL developers to see if there's an issue. It's generally not Apple's fault that a third-party app that hasn't been written for a version of macOS doesn't work.

Please don't raise bugs in a new version of an OS in a post here on the Developer Forums. Apple's engineers aren't reading through these pages to see if anyone's found a bug. These forums are for third-party developers writing apps for Apple's platforms to discuss issues with their code. You need to raise each individual issue separately at https://www.apple.com/feedback/ You can post the FB numbers here if you want, so that others can link to them.

Don't forget to tip your server / mark your answer as accepted :)

You should get in touch with the developer of the app, telling them the model of Mac, the version of macOS etc., and how much RAM you have. We can't really help you with this on the Developer Forums.

People really need to stop posting one-liners in the Developer Forums for issues they've found in a beta of a new OS. Please raise a Feedback report, and let Apple know directly. We are not Apple developers, and raising your issues here won't generally be seen by Apple's actual, employee developers. https://www.apple.com/feedback/

There's nothing we can do in the Developer Forums for your issue, other than suggest you contact the manufacturer of the USB-C earphones and see if there's a software update or something. Does this issue only happen with Apple Music? How about Spotify, or some other service that streams music? How about Netflix?

Contact the developer. We can't help you with an issue like this.

On iOS 17.5.1 it's in Settings > Privacy & Settings > Developer Mode (at the bottom).
