Shouldn't the countdown date be set in the email, in the JavaScript, so that the email counts down to the time inside that email? If you're worried about someone viewing the source of the message and going to your server to see the surprise before the timer is up, then your server needs to not show the surprise until the time has passed on the server.

You need to click the "Install Profile" button to download the installer utility.

What errors are you getting? Are you downloading the .ipsw file and trying to install it, or are you trying to download it on the device? I find that downloading the .ipse file then installing it via the Finder works better. In Finder, Option-click the "Update iPhone" button and select the .ipsw file you downloaded.

Have you tried my suggestion of using Finder to update it?

Have you tried signing out of your account inside Xcodes preferences, and signing back in? That should refresh the developer profiles.

This isn't a question for developers of apps. You need to take your product support question to the Apple Support Forums.

How about you debug your app in Xcode with iOS 16 and find out where the crash is happening? Perhaps something changed between iOS 15 and 16, and you haven't updated your app to handle it?

You keep asking the same question here. How are we supposed to know why your list info is gone if we can't see your code? This is like me asking you why there's a 2-pixel gap at the top of one of my views... "Which view? Can I see your code?"

You could probably mock the database so you don't need to rely on it in each test. And yes, as you noticed, unit tests shouldn't depend on one another.

What did print("seedItems", seedItems) actually print?

Sorry, no. There is zero information in your post for us to help you. you;'re just going to have to debug it on your own, or come back here if you have some code that's causing something to go wrong. Generally, you need to update your apps to handle the new ways and features of a new version of iOS. If you don't do that, you're likely to hit these issues.

The code in that link is from 2012, with updates in 2018 etc. Can you post your actual code, and let us know which version of iOS you're targeting, etc.?

Go into App Store Connect for your app and see if you've accidentally set a date for the update to be released. It's possible that the update is rolling out across Apple's servers, and it will just take a bit of time to be available everywhere. No, your users don't need to delete the app to get an update. If you want to inform your users of an update - and you don't have their contact details (through some sort of signup inside the app) - then you could always use a simple version check: On a server somewhere, save a small text file that contains the current version number, i.e. 1.0.0. In your app, grab that text file and read the contents. If the version in the text file is newer than the version reading the text file, alert your users that there's an update available.

Lock Screen Widgets aren't running apps - there's no real code behind them, so you can't do much with them. They are simply snapshots in time, so they just show a set of data at a certain time. You can't do animations in Lock Screen Widgets.

Have you deleted the storyboard called Main? If so, the only way to make it work again is to put it back (maybe from a backup?). If you've lost it - oh dear - you'll have to create a new storyboard and start again.
