  this repository, please delete this section.

[REQUIRED] Step 1: Describe your environment

• Xcode version: 12.3
• Firebase SDK version: 7.31.0
• Installation method: Swift Package Manager (select one)
• Firebase Component: Firestore (Auth, Core, Database, Firestore, Messaging, Storage, etc)

[REQUIRED] Step 2: Describe the problem

Steps to reproduce:

What happened? How can we make the problem occur?
This could be a description, log/console output, etc.

If you have a downloadable sample project that reproduces the bug you're reporting, you will
likely receive a faster response on your issue.

Relevant Code:

Hi! Sorry for the vagueness here, I'm trying to look towards a more reproducible method.

In short, I was working on archiving my app, which uses SPM and has Firestore, Dynamic Links, Messaging, Auth, and Storage onto a framework target. The main app uses the framework and usually runs fine. As I compiled for MacCatalyst, I had no issues, but when I compiled for any iOS device, I got the error

scattered reloc r_address too large for architecture armv7

I've tried setting armv7 as an excluded arch everywhere, but no avail. I'm wondering why it's even compiling for armv7 though. My deployment target is iOS 13.0+ so shouldn't it only need arm64? I found an old tweet regarding a similar bug, but for i386 that recommended a refactor due to the project being too large, but their project was about 100x bigger than mine.

From googling the error, it looks like a long-standing Xcode issue related to the size of the app.

As to why, Xcode is building armv7 when the deployment target is iOS 13, that seems like an Xcode/SPM bug. There's no reason to build and link dependencies arm7 if the app has something higher, even if the dependencies support iOS 10.

Perhaps worth asking at https://forums.swift.org/c/development/SwiftPM/ ?

I'll leave this open for discussion for awhile, but this is unlikely to be a Firebase issue.

Interesting, I'll definitely post there and hope to get a better result. I'm hoping it's not some weird size bug, as my app is only 10K LOC

[Umar-M-Haroon]

here's an update, if I connect my device, select that as a run destination, then hit archive, then it succeeds.

We'll likely need a reproducible example to provide additional assistance here.
