@debug45 - Wow, really weird. Thanks for reporting. I'll take a look.

[jawwad]

We don't have any hardcoded paths, at least with my name within the repo itself so this must be some weird side effect of how we are building. Also, this was the first release built with Xcode 13.0.0 instead of Xcode 12.5.0 so perhaps some build behavior changed. (We build with older versions for some time to provide backward compatibility, since Xcode guarantees forward compatibility but not backward compatibility, i.e. a release built with Xcode 13 may not work with Xcode 12).

[samodom]

@debug45 We're having trouble reproducing this issue with a sample app. Do you have a simple app that you can share showing this behavior?

[adarhef]

This is happening to me as well (Xcode 13.3):

@debug45, @adarhef - Could you see if this is happening in a brand new empty project for you? You can create a new app or use the FacebookTest.zip sample project in https://github.com/facebook/facebook-ios-sdk/issues/2047#issuecomment-1077389896.

[adarhef]

I just tried running FacebookTest.zip and didn't get any warnings, so I guess it's somehow related to my setup. Any pointers maybe?

[joshuapoq]

You're not the only one with these errors - I also tried the same, matching our setup, and had no errors. We use XcodeGen in our projects so I plan to go through the build settings to see if I can figure out which is causing it.

[joshuapoq]

Enabling DWARF with dSYM file for debug produces these warnings on the FirebaseTest.zip @jawwad @adarhef (which makes sense 😅). We have this enabled based on Firebase install guide for its automatic symbol uploads. I used to disable this but gave up fighting Firebase on that one. I assume these warnings would also show on Release config builds.

[jawwad]

@joshuapoq - Thanks for figuring this out! I can confirm that changing from "dwarf" to "dwarf-with-dsym" reproduces this issue. So changing "dwarf-with-dsym" to "dwarf" for the Debug Information Format setting will get rid of these warnings for the Debug config. Now the next question to figure out is why these hardcoded paths are there in the first place.

[wooseongkim-29cm]

@jawwad Is there any update on this? We had same issue on our project. Hope this will be fixed on next update 🙏

@jawwad any update?

[username0x0a]

This warning seems even more relevant for production builds:

Linking a static library that was built with -gmodules, but the module cache 
was not found.  Redistributable static libraries should never be built with 
module debugging enabled.  The debug experience will be degraded due to 
incomplete debug information.

Hoping for a quick fix. 👍

[joshuapoq]

Just for my two cents. I'm not convinced this is an issue specifically on Facebook's side. I'd think this is more likely an issue Xcode 13 or SPM has introduced. I've seen similar warnings from some of our frameworks but we do have some legacy Objective-C dependencies. Would love to hear what you find from this!

[zeusent]

I see these weird warnings with the latest Facebook SDK as well:

[tb-rendity]

We're getting these same warnings as others.

Its a case of enabling DWARF-with-dsym to let crashlytics debug builds to effectively provide test data or put up with these somewhat annoying warnings.

Could we see a fix for this soon? We have a set of best practices that this doesn't really fit well with

Still happening in latest 14.1.0

[joshuapoq]

Please can we get an update on this @jawwad at least on what investigation has been done and why this one has been and will be hard to fix?

I'd guess this is caused by some parameter set in the project or passed to build commands within your tooling. From my own experience I'd guess it's either an easy fix or it'd require a tooling rewrite but I'd love to know why this is taking so long to fix.

We have around 30 projects using Facebook and these warnings are a frustration against our code health policies.

[piercifani]

I can't believe this is still not fixed... Think about how many teams that can't properly keep a healthy codebase because they integrate with the FB SDK.

[zvjerka24]

On my end similar situation but with local path (SDK version 14.0.0)

We made some updates in the v15.0.0 release that we're hoping will fix this issue. Can anyone currently experiencing this please try that version to see if is solved for them?

For me upgrading to 15.0.0 seems to remove those warnings. Glad to have my warnings pane empty again! Thanks!

Closing for now since this is fixed as of 15.0.0.
