OK, I'm at my whits end, struggling after updating the CMP Firebase Lib, now I get:

Showing All Issues
java.lang.Error: Linking globals named 'kniprot_cocoapods_FirebaseAuth0_FIRUserInfo': symbol multiply defined!

when building iOS app, I've double check pods/spm, deps etc. Blown everything away then rebuild/imported etc

[Stan van der Bend]

Maybe this will help:
https://youtrack.jetbrains.com/issue/KT-50077/Linking-pods-error-on-Kotlin-1.6.0

Also provide your build.gradle.kts and versions so people may be able to help you better.

[chrisjenx]

Yeah the main issue is that I do that move the pods out, then I go from multiply defined to now I get: ld: framework 'FirebaseAuth' not found

Rock and hard place achieved...

cocoapods {
        version = "1.0.0"

[Stan van der Bend]

Did u see that flag "linkOnly" in the pod dependency declaration function

[chrisjenx]

Yeah tried that, get a different error, lemme run and grab that one...

[François]

Did you try this way ?(advertisement myself 😛)

[chrisjenx]

No, lemme look 🙂

[chrisjenx]

So the linkOnly method gets:

Lemme looks at Francois

[François]

Maybe I’m getting lucky to have some feedback 😄

[chrisjenx]

You use swift export method which I'm not

[chrisjenx]

I would like to switch to, but the hellscape which is KMP and iOS dev doesn't let me yet

[François]

So SPM is not an option for you?

[chrisjenx]

I wish

[François]

Stuck in a dying CocoaPods, 😭

[chrisjenx]

Yeah, no kidding, the icons don't even load on the CP site now!

[François]

anyway, for your current config, can you move to isStatic = true ?

[chrisjenx]

Yeah trying that now

[chrisjenx]

Seems to be getting further

[François]

in dynamic, you need to explicitly add all firebase require dependency as linkOnly

[chrisjenx]

I mean, is there anything there stopping me using SPM export? I think before firebase didn't support it when I started, but now it does

[François]

You can use both CocoaPods and my plugin.

[chrisjenx]

Lemme get this working as I need to cut a release then I'll try in a different branch

[François]

All your cocoa deps are SPM compatible, you can try the other way. I would like to know if my work is helpful 😄

[chrisjenx]

Finally got it to run,

[chrisjenx]

combination of linkOnly + static = true + adding pods to the iOS project got i there

[chrisjenx]

FML

[chrisjenx]

Deffo should move to SPM clearly

[Jimmy Nelle]

@François you convinced me! I'm trying your lib today for my Firebase CMP App 🙂

[François]

@Jimmy Nelle Tell me what you’re thinking about my plugin on PM 😄
