Adding FirebaseAnalytics or FirebaseCrashlytics breaks SwiftUI previews on macOS Sequoia in Xcode 16 due to missing slice for arm64e

[tnymlr]

Description

After adding FirebaseAnalytics and/or FirebaseCrashlytics as a dependency using SwiftPM on MacOS Sequoia (exact version I'm running is 15.1) in Xcode 16 into an empty, newly create project, SwiftUI previews stop working due to missing slice for arm64e-apple-macosx21.1 architecture

Reproducing the issue

• Create new macOS app and choose it to be SwiftUI app.
• Navigate to Package Dependencies
• Add Firebase using https://github.com/firebase/firebase-ios-sdk.git
• Check FirebaseAnalytics and/or FirebaseCrashlytics in the list of available packages to add to your target
• Open generated from the template ContentView and make sure canvas is enabled

Kindly find the project attached.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

[rizafran]

Thanks for reporting, @tnymlr. This seems related to #13603. I was able to reproduce the issue but the issue disappeared when I tried to disable the Legacy Previews Execution in Editor -> Canvas. Could you try if this works for you?

[tnymlr]

@rizafran Indeed, it is related, I believe the root cause is the same. And yes, the setting does solve the problem.

[rizafran]

Thanks for the update, @tnymlr. I'm glad to hear that the issue has been resolved. I'll now be closing this ticket but feel free to comment if you encounter the issue again or if you have other questions.

[tristan-warner-smith]

Can we reopen this one @rizafran ? Relying on Legacy Preview mode isn't an option for us.

[paulb777]

I suspect that like #13603, this is an Apple issue, but I'll reopen for additional analysis and thumbs-ups.

fwiw, issue persists in macOS 15.2 with Xcode 16.2

[ncooke3]

Thanks, @vade. I will update my feedback ticket. It appears there was a previews fix that went into Xcode 16.1, but it didn't resolve the issue this thread is documenting.

[vade]

Good luck haha. I think we're all gonna need it.

[paulb777]

Hmm, I'm able to successfully preview the attached TestApp with Xcode 16.2 on macOS 14.7.1. Perhaps this is a macOS 15 only issue?

[paulb777]

Is changing the Deployment Target a workaround?

[tristan-warner-smith]

In our case the only platform is iOS where this issue continues to manifest, so changing the deployment target isn't a workaround. We're compiling on Sonoma machines, but not deploying for macOS.

[paulb777]

The Xcode 16.3 beta release notes list several fixes: https://developer.apple.com/documentation/xcode-release-notes/xcode-16_3-release-notes#Previews

use legacy previews execution

I checked this option to preview normally. 😭 Xcode 16.3 (16E140) & macOS 15.4
