Assets are not added to the bundle

[JeroenJochems]

When compiling an app clip in xcode, some of my assets are not added, or are somehow unavailable in the app:

Error: Unable to download file: Error Domain-NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo-{NSErrorFailingURLStringKey-icomoon.ttf,NSErrorFailingURLKey=icomoon.ttf...

When I switch to the normal app scheme, it does work without problems.

I have the same issue when trying to load a font in my assets folder. It is trying to access the url:

https://127.0.0.1:8081/assets/assets/fonts/Pacifico-Regular.ttf?platform=ios&hash=.....

I'm not sure how things work under the hood, but it seems weird to me that the 'assets' is duplicated at the beginning of the url.

did anyone find a solution to this problem?

I did few checks on simulator. Here are my findings:

• The url is valid even if it is containing assets twice.
• It does not help to to use full IP address instaed of localhost.
• Url works inside Safari on simulator
• Fonts are loading if Build configuration is set to Release. I guess this is due the fact that in release mode are fonts already bundled in the app and do not download via network.
• App Clips does not support gRPC network call FR: App Clips support for Firestore, Database, and others firebase/firebase-ios-sdk#6211 However I do not think that font loading is using any of it.

@RobertSasak related to your findings about not supporting gRPC network calls, it looks like this is failing because App Clips don't support background download sessions.

The error I see in the logs is failed to create a background NSURLSessionDownloadTask, as remote session is unavailable. There's a relevant support question on the Apple Developer forums: https://developer.apple.com/forums/thread/669148
