I found that I didn't need the Apple server URL when using Apple Hosted assets. However, a consistent download has proved elusive. There is an Apple Support doc

I was also able to use Xcode as my IDE using the Other : External Build System template and /usr/bin/make as the External Build Tool with a makefile and gnufortran. Run from the Terminal.

After a week or two on revisiting the review page the question list was updated and I was able to submit the app for review after answering all the questions.

Feedback IS FB24353629 submitted

Agreed. I was also disappointed to hear of the black screen. With an earlier version I included the videos in the app binary. I thought using Background Assets should be a better experience for the user. In my testing with TestFlight the asset is downloaded in a second or two, no more than 5 seconds. I didn't think about the user getting a slower or no download. I've added an alert when an asset isn't downloaded so the user should get some feedback. The problem I'm trying to explore is the difference between my experience testing with TestFlight (1-5 second downloads) and the reviewer's experience (> 1min or no download) with the same binary. To my mind one possible reason for the difference could be a problem with the Background Asset system or my use of the system. I had originally got the asset pack upload/approval out of step with my app submission but was able to get versions for three platforms accepted. Thanks for your comment. David

I have a similar problem but haven't got as far as @lami2. I have an app on the app store that I have expanded to multi-platform. Anticipating a larger audience (;-) I thought I'd try to use Apple Background Assets. I can get the app versions to work with my hosted assets. Local server hosting ran into a certificate issue with the local cert. I thought I should upload the assets to the Apple server and try testing with TestFlight. All the versions work with TestFlight except I don't have the relevant Apple URL. The asset packs are all uploaded and ready for internal testing. As I expected the error I'm seeing when app tries to access assets is 'A server with the specified hostname could not be found.' Can someone point me to the Apple server URL. Thanks, David BTW the app name is Pharmacy Tutorials

Looks like an old thread but I'm using the latest macOS and Xcode...I've uploaded some videos as .aar files. All good, except I can't see the URL for downloading the videos with my app. I've uploaded macOS and iOS version for testing with TestFlight. I think I have everything in place except for the URL.

Try 'logging' in with your API key. Xcode : Settings : Intelligence : Providers : Anthropic after downloading the Claude Agent. I wasn't able to use my free account by signing in but it works (for now) when I entered my API key

I selected Opus and Sonnet. Is Sonnet 'better' for coding? Maybe leaving it at Default is best. It seems logging into Anthropic requires a paid account. Using a 'free' API lets you use the models for free, for now? Codex with a 'pay as you go' account is very capable but I'd like to use Claude going forward. I'm more of a hobby coder at this point and the Pro account is 'big' step up. ;-) maybe I should start charging for my apps. Hopefully I'll get a good feel for Claude in it's current configuration and can accept the value added of the paid account. [Just one more subscription]

Using Xcode : Settings : Components and deleting unused Other Installed Platforms as shown in thread https://developer.apple.com/forums/thread/810415 which points back to this thread. DaisyDisk went from 240/68 GB to 345/76GB. Now orange instead of red! Finder still shows the same size.

Inside System : Library I have the folder AssetsV2 with large Folders. com_apple_MobileAssest_iOSSimulatorRuntime 85.83 GB and .com_apple_MobileAssest_xrOSSimulatorRuntime 56.23 GB. Also _appleTVOS.. 21.41 GB and _watchOS.. 18.87 GB. I've tried xcrun simctl runtime list and delete. After a computer restart xcrun reported Total Disk Images dropping from 267.9G to 106.8G BUT no change to Finder reported sizes. DaisyDisk showed 99G free and now 240G or 68G A lot of disk images appear in Disk Utility but eject doesn't work for most of them, maybe none. In Xcode I see a lot of simulators. I was able to delete many of them but no change to memory reported by the Finder. It looks like I've tried the suggestions above. I've run out of ideas.

Thanks I finally got back to this. the security find-identity command was very helpful. The required identity was missing when I checked. Creating the Developer ID installer: identity was the missing piece. I had previously used an Developer ID Application: identity. The provided links were also very useful. Thanks Quinn for your help. David

@CarlS Thanks for this info. I looked in info.plist and found the previous bundle number despite changing the value in General tab. Hopefully that will help. @MikeNelson I had to double-click on the old value in the info.plist before I was able edit it. Maybe that is what you were seeing as 'hard coded', maybe

I forgot to add Network activity to the App Sandbox.

Ha. got an iOS version of the app together. Validated OK. Took a long time to upload but completed OK. Remember this includes the modified model in the app bundle. Got an email from App Store Connect. "Please correct the following issues and upload a new binary to App Store Connect. ITMS-90558: Thinned app size is too large - The “/Payload/PK-LLM.app” app bundle in the universal variant is 4 GB, which exceeds the maximum allowable size." Looks like I'm going to upload the specialized model to HuggingFace. Also, the current macOS version give an error after compiling (but not always). Could not launch “PK-LLM” Runningboard has returned error 5. Please check the system logs for the underlying cause of the error." The logs are full of a lot of stuff I don't understand. Maybe uploading to HuggingFace is the way to go.
