SwiftUI Previews are not working #46

Open dancarvajc opened 1 year ago

dancarvajc commented 1 year ago

Hello, thanks for creating this package, it really helps with build times. Just one problem, I can't get the Swiftui Previews to work. The official firebase package works without problems. Do you know if it is something specific with this mirror?

FWIW, I have no issue with Previews with this project included. But there is apparently an ongoing issue with Previews and binary SPM: Discussion on Dev Forums

i think it works in 14.1 beta2

akaffenberger commented 1 year ago

Which libraries are you using? I can try to repro by adding some more examples to the iOS Example project.

From my testing so far, certain libraries work with previews while others don't. ie Google Sign In works, In app messaging works, Firestore crashes it. However, the Firestore crash I can repro with the official package too, so that might be a different issue.

it works in xcode 14.1

We are seeing a "Preview crashed" issue. Using FirebaseAnalytics, Messaging, Functions & Performance

akaffenberger commented 1 year ago

On XCode 14.2 I'm still seeing a previews crash for Firestore (in both this repo and the official repo), but Messaging and Google Sign In still works fine. When I find some time I'll give Analytics, Functions, and Performance a try.

I also get the "Preview crashed" message. Looking at the diagnostics in ~/Library/Logs/DiagnosticReports:

Which seems to be the same crash mentioned here. However if I integrate the Firebase libraries using their official SPM package the previews doesn't crash, but the time it takes to compile FirestoreStore is close to unbearable though, which is why we switched to this package to begin with :)
