“Code Data's diagram editor style facilitates powerful collaboration on an app's data model. Apple, please bring this Xcode capability back!!! Losing this feature introduces immense cognitive overhead in the development, design, and maintenance of a Core Data data model. The best analogy that I can come up with for this backwards move, is that it's the same as asking Mac users to give the GUI they overwhelming love and appreciate, and force them to revert back to using the command line.” Correct. Same with me! Xcode 14.1 from October 22.

I suggested a workaround using Xcode 12.4 and my message was deleted. I just would like to know why?

Suggestion: get an old Mac (mine is Mac mini late 2012, install macOS Catalina (10.15 7) and Xcode 12.4 (12D4e). CoreData graph editor works ok. My idea is to move the CoreData stuff to Xcode 12.4 and build it as a package and bring it back to Xcode 14.1 by importing it as a package. I did not test the package idea yet.

https://cs193p.sites.stanford.edu It’s the best by far. So sad they did not refresh the classes in the last 2 years. But still very good.

Yes, that bug is there since day 1. Solution: download only and only Xcode. Unselect all platforms. After download install Xcode and run it. Create a new project. Then click on all paltforms, one by one. Xcode will tell you the selected platform is not installed and installation is needed. Agree and install one by one. It has been working for me since day 1. Have a good day! Johel

I am evaluating Xcode Version 15.0 beta 4 (15A5195m). Same problem.

Hi, I strongly suggest to you to watch these classes: https://cs193p.sites.stanford.edu It will save you a lot of time and the solution for your question is there in the first class. Have a nice day, Johel

gillesduif, Confirmed! It compiled! But when running at the Simulator I got: nw_socket_copy_info [C1:2] getsockopt TCP_INFO failed 102 nw_socket_copy_info getsockopt TCP_INFO failed 102 AddInstanceForFactory: No factory registered for id <CFUUID 0x600003c24540> F8BB1C28-BAE8-11D6-9C31-00039315CD46 Class for component AccessibilityComponent already registered Class for component ImageBasedLightComponent already registered Component Shadow already registered Component Shadow already registered Unexpected CARE Entity state: CALayerClientComponent destroyed unexpectedly in the app. layerId: 6.611.696.850.093.839.007, contextId: 0, name: _MRUIPlatterOrnamentBackingWindow (com.example.apple-samplecode.World9X2AS5344F) Unexpected CARE Entity state: CALayerClientComponent destroyed unexpectedly in the app. layerId: 9.506.802.391.458.032.199, contextId: 0, name: _MRUIPlatterOrnamentBackingWindow (com.example.apple-samplecode.World9X2AS5344F) The app at the simulator freezes, there is no World only an empty window.

Hi All, It looks like the culprit is the Xcode beta4 Vision Pro Simulator. Try this: create an app using the Multiplatform template, change nothing, compile and send it to the Vison Pro simulator. It will freeze the same way Hello World freezes. Same happens with the Backyard Birds code sample from Apple. I guess it is also linked with the problems in the Preview window in Beta4. Better wait for Xcode beta5. Regards, Johel

Hi All, Xcode 15.0 beta 5 working better than previous versions. Hello World as published by Apple compiles and runs on Apple Vision Pro simulator. Same for the Multiplatform template test. Hello World still crashes here when I choose the View Globe or View Orbits or View Outer Space buttons. Error is: } catch { fatalError("Failed to load a model asset.") } Xcode 15.0 beta 5 (15A5209g) macOS Sonoma 14.0 Beta (23A5301g) Mac mini 2018 16gB RAM (Intel processor) Regards, Johel

Hi All, There is a new version of HelloWord at https://developer.apple.com/documentation/visionOS/World All those problems listed before are from the first version from June 16 2023. The new version is from July 14 2023. It compiles with no problems and runs at the simulator also with no problems. Download it and enjoy. BTW, that's a fantastic app!

Same with me. But I tried to register myself as a developer, could not reach the payment page, send a message asking “what should I do“ and I am waiting. For a couple months now…
