Xcode version

14.2

Facebook iOS SDK version

16.3.1

Dependency Manager

SPM

SDK Framework

Core

Goals

Release the app to the app store

Expected results

App release (linking) is failing while releasing with Xcode 14.2. For some internal reasons, the pipeline has to use this version of the Xcode.

When I revert the version to the previously used v16.2.0, the app is linking fine.

Actual results

⚠️ ld: Could not find or use auto-linked library 'swiftCompatibilityPacks' ⚠️ ld: Could not find or use auto-linked library 'swiftCompatibility56' ⚠️ ld: Could not find or use auto-linked library 'swiftObservation' ⚠️ ld: Could not find or use auto-linked framework 'Symbols'

❌ ld: symbol(s) not found for architecture arm64

❌ clang: error: linker command failed with exit code 1 (use -v to see invocation)

Steps to reproduce

No response

Hi @gameboys84, While looking into your issues I remember that at some point I had the same one. ❌Undefined symbol: _$s10Foundation3URLV6string25encodingInvalidCharactersACSgSSh_SbtcfC

It seems the error depends on what other libs you have. Since I updated multiple libraries at the same time, initially I didn't know which one was problematic and I was reverting one by one. At some point that was the error.

Thanks for the reply, I just upgrade the Facebook sdk from 12.3.1 to 16.3.1, and fixed some other errors, and this is the last 3 error of my project.

Furthermore, I saw this error sometimes, and not sure there is relative or not.

Downgrade to 16.2.0 should fix your error.

Yes, a friend in need is truly indeed. I just try the version 14.1, 15.1 is OK, and 16.2.1 is OK too..
This must be an ISSUE! @facebook-github-bot

I'm wondering why no one else reported this issue, since this version has been live for almost 1 month.

Having the same issue since couple of days. What is the best way to downgrade to 16.2.1?

Here is the issue in my case:
