I’m using UIKit and this form of Predicate works for me.

That image is not of a website. That image is of Xcode. You should have Xcode.

Thank you for your help. Your input did put me onto the entitlements. I did run syspolicy_check on my app that I purchased. When I ran it with notary-submission, I got AppleMobileFileIntegrity Error Severity: Fatal Full Error: No matching profile found Type: Distribution Error When I ran it with distribution, I got Notary Ticket Missing File: MyApp.app Severity: Fatal Full Error: A Notarization ticket is not stapled to this application. Type: Distribution Error

The issue started with macOS 14.0 Sonoma. I don't have any login items.

@Tomato Yes, I did that thanks.

On second thought, it might be doable as a sidebar. Thank you very much for your help.

Are you trying to save an Arrsy of data?

When I say the above don't work, I mean they always evaluate to false.

When I played with this situation on Swift Playgrounds, the starts(with: worked no matter if the ? was used after variable of if the ? was used. The problem is that this condition is being evaluated within the Predicate macro and I think there's something going in with that so that only the data.variable?.starts(with: SomeString) ?? false one works.

Here's my original thread which I closed too early. https://developer.apple.com/forums/thread/735397

data.variable?.starts(with: SomeString) != nil always evaluates to true. The one that works is data.variable?.starts(with: SomeString) ?? false

Well, it crashed because I initialized items to nil, init(items: [ChildItem]? = nil). But init (items: [ChildItem]? = []) worked, did not crash.

Several of us have had an issue with Data meant for Images on Xcode 15 Beta 5. Beta 4 worked fine. Beta 5 is broken. I recommend filling a Feedback.

Also, if I change my model to include a structure, that may persist the data, but how would I sync a structure with CloudKit? No, they have to fix this issue. I don't see a viable workaround that includes iCloud syncing.
