Turn off the "Content & Privacy Restrictions" switch?

You mean this, in InfoPlist.strings: <key>NSCameraUsageDescription</key> I used <string>We need to access your camera so you can take a photo and use it as a background image for your events.</string> but you need to tailor it to your own particular app.

According to this page: https://developer.apple.com/support/xcode/ you need Xcode 12.4. Just go to https://developer.apple.com/download/all/?q=xcode and scroll down until you get to the version you need.

Firstly, it's "iPad". Secondly, which betas of iOS 17 and Sonoma are you on? What have you tried? Are there any messages on the iPad when you plug it in? Does it show up in Xcode via Wi-Fi or when connected?

Xcode 15 is in beta, you can't upload apps built with it yet. It probably shouldn't crash, but that's irrelevant to the actual issue.

This again? Do you do anything besides grumble about this? Have you actually raised this with Apple? No one in the Dev Forums is going to be able to help you with this - as I suspect you know - so please raise a bug report and let Apple deal with it. Spamming these forums doesn't help you or us.

This doesn't make any sense. And also, please use the code formatting.

The first one seems overkill for what you get as a result. Unless you're doing something more involved in text and hello - which you aren't in these examples - there doesn't seem to be any point in abstracting this out. Keep it simple.

The reason I say you're spamming the dev forums is because every topic you've ever started here has been about PDF editor apps, and how there are scams on the App Store for PDF editor apps. Every response is a grumble about it, except the one where you said that the issue has been solved by the App Store team. If the App Store team solved it, why do you think us developers can solve it for you? I understand that scam apps are a problem, but I will say it again, no one on here can help you. You must get in touch with the App Store Team, not random developers who use these forums to fix issues with their code etc. Your issue is not with code or anything like that; it's with the App Store team, and you should simply get in touch with them. A member of Apple's team actually told you how to report this issue, but you continue to raise it here where nothing can be done about it:

If spammers are using new tricks, then report them to the App Store as instructed to do so by one of Apple's staff who posts here on these forums. You can keep posting new threads about the issue, but no one here can help you. We are developers looking for fixes and help with our code. If there are issues with the App Store, then tell the App Store team! It's really not that difficult. I can't be bothered trying to help you anymore.

Are you using anything in iOS 16.5.1 that isn't available in iOS 16.2? If not, just install Xcode 14.2, and drop the target version of your app to iOS 16.2. If you're unsure, change the target version to 16.2 and see if it works as normal.

No.

You can't use timers in a widget, so I'd guess they're also disabled in Live Activities, too. You need to implement a timeline for the events, i.e. add an entry for the start time, and one for the end time, and hope it works. One of my apps has countdowns in the widgets, and everything would be far simpler if I could use timers, but I can't.

The error suggests that a specific line in your code is incorrect, but you haven't given us any code to work with. What's the code on the line that causes the error? Have a look here for some background on optionals.

Why don't you want to add iPad as a destination? That would fix it. You would need to make sure your app looks correct and works correctly (as Apple stated), but that's kinda what you have to do.
