The accepted answer is not an answer, but a comment. I have the similar issue with ACarousel preview. LinkDylibError: Failed to build PaywallCarousel.swift ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation) This discussion is similar and have much more activity: https://forums.developer.apple.com/forums/thread/736152?page=2

Guys, actually, I found an unexpected workaround! If you can isolate the view, that potentially crashes, try to extract it in a separate View file. Make a custom subview that uses the 3d party lib, that causing the crash. In my case it was ACarousel. Then, in the view that you actually need to preview, use this subview. If the 3d party lib isn't imported there, the preview will work. Fantastic! This cost me 6 hours of work.

To save your time I copy-pasted Michcio's answer from the SO link posted by @Claude31 above: let imageAttachment = NSTextAttachment() imageAttachment.image = UIImage(systemName: "checkmark.circle") // If you want to enable Color in the SF Symbols. imageAttachment.image = UIImage(systemName: "checkmark.circle")?.withTintColor(.blue) let fullString = NSMutableAttributedString(string: "Press the ") fullString.append(NSAttributedString(attachment: imageAttachment)) fullString.append(NSAttributedString(string: " button")) label.attributedText = fullString

One of GPTs suggested me to make App Intent declaration public. This actually worked.

Try marking the entire MyIntent struct as public. This advice worked for me.

Check that intentClassName corresponds to old Siri Intent auto-generated class name. Declare your AppIntent struct as public.

You have to use Logger for that. It will output the messages to Console.app, as well as to Xcode console. However, you have to specify them as public, otherwise the message text will be hidden. Like this: import os.log let logger = Logger(subsystem: "com.kelin.vladimir", category: "Debug") // Log level: notice. Explicitly specified `public`. logger.notice("\("TEST", privacy: .public)") In order to protect your private data in prod, consider using #if DEBUG macro.

We ended up switching to another backend provider 😢 But I hope one day we will return to CloudKit, as it maturates and gets better.

@iphonegamedeveloper, any success? I guess if scheme isn't https or http that we can assume it's custom in most cases.

I had the same issue, @SpaceGrey. You solved it by using "All Sizes", I solved it by staying at "Single Size" but replacing JPG with PNG.

I was able to resolve the issue by switching to URL Schema. The tricky part here, is that the schema should contain at least some path components. First I tried schemes like this: myapp-halloween:// And got the error when tried to save the Custom Product Page: ⚠️Your changes could not be saved. Try again later Initially it was unclear at all what's wrong here. I thought that maybe URL Schemes are not acceptable at all, so that's why we tried deeplinks. And got the similar error as OP: on the first attempt deeplink isn't activated even on iOS 18.2.1. But experementally I found that if you add some path components, like: myapp://halloween Then everything works fine. CPP submitted without issues and the scheme opens the app and the URL gets received.

Similar issue: // Sending 'center' risks causing data races let granted = try await center.requestAuthorization(options: options) Silenced by using @preconcurrency: @preconcurrency import UserNotifications

I also have SE2 and constantly get various errors while debugging watchOS apps with Xcode. Connection is very unstable.

Test Wow! Looks like I can't delete this post. To mods: could you please enable post editing? I need to delete the .watchface link from the question.

@darkpaw, any luck with this issue?
