I'm getting message "This operation can fail if the version of the OS on the device is incompatible with the installed version of Xcode. You may also need to restart your mac and device in order to correctly detect compatibility." when I try to run an Xcode iOS project on my iPhone 8. I'm using Xcode 13.2.1 and iOS 15.4 on my iPhone 8. This post in this forums gives the solution to restart the iOS device and I did that and also restarted the mac. My Mac has macOS Monterey 12.3. My Xcode, Mac, and iPhone 8 all have the most recent updates. That post gives an answer for the same problem but with iOS 15.2. I have recently changed settings in my iPhone 8 in Accessibility. Could that affect anything?

How do I sort an array of dictionary objects based on the value of the dictionary? I understand I should use the sorted method of the array, but I don't understand the notation that uses $0.1 and $0.0. Where is the documentation on that?

What is the word in programming that means that checks a condition for true or false, and if the condition is false, code is run to make that condition true, so that if the condition is checked again, it would be true? I believe I have seen something in Swift or Foundations that does this as applied to different things.

Why am I getting an error message when I try to validate an archive that says, "No accounts with iTunes Connect access have been found for the team. iTunes Connect access is required for App Store distribution."?I have never gotten this error message before. What should I do?

Anyone ever use CNFetchResult successfully? I find nothing on the internet, on stackoverflow, and in Apple Developer Forums. The only thing I have found is Apple Documentation for it. It says CNFetchResult is a Generic Class. What exactly does that mean. I found an explanation that gives its definition, but the rest of the explanation is very long winded.

I signed out of iCloud in the iPhone 8 Simulator, and it has shown the screen saying "Removing iCloud data..." showing that it's working for a few hours now. When it did this before, I shut down the Simulator and when I opened the Simulator again, it shows that it never logged out of iCloud.

I am having trouble creating a sandbox tester account in App Store. I keep getting an error message saying there are one or more validation errors when I click on "Invite", but there are no indications of any errors. None of the fields are marked with red for an error.What is going on? Is there a limit of the number of sandbox tester accounts I can create? Is anyone else having trouble with this?
