iOS 14 App Clip SIGABRT crash - Library not loaded: @rpath/FBLPromises.framework/FBLPromises

[thoughtcastapp]

Steps to reproduce:

Have an app that uses Firestore for its DB (made a core app and an app clip as a separate ios target before app clips were available). Added an app clip and used cocoapods to add the firstore libraries to the app clip. Linked the app clip to my pre-built app/migrated the files over and tried to simulate it. Build compiled and ran, but it crashed before launching with the following message:

// TODO(you): code here to reproduce the problem

To reproduce, make an a new ios app in xcode, add an app clip, make a new podfile and add firebase to it (I added Auth, Firestore and Database). Then, follow the stock instructions for initializing firebase in the app clip and run the app clip to a simulator or device...

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hi, @thoughtcastapp sorry for the issues you're seeing.

Re: Library not loaded, this is the same issue as #4889. Specifically, the workaround here: #4889 (comment)

Unfortunately though, Firestore does not currently work in App Clips on device. You can follow along with progress at #6211, and I'll close this issue.

gotcha, just a note for anyone reading this after the ticket was closed, I tried #4889, but there are some libraries that swift won't allow static linkage to in firebase (I believe boring ssl is one of them), so that solution will not work for this issue...here's to hoping you guys can figure out a solution :)

@thoughtcastapp try declaring the podfile with modular headers. That's what worked for me.

I removed use_frameworks! for the appclip target in my Podfile and added modular_headers => example:
pod 'Firebase', '6.30.0', :modular_headers => true
pod 'Firebase/Functions', '6.30.0', :modular_headers => true
pod 'Firebase/Auth', '6.30.0', :modular_headers => true
pod 'Firebase/Database', '6.30.0', :modular_headers => true
