xcode 13 wont build due to clash with GCDWebServer

[stefoid]

How frequently does the bug occur?

All the time

Description

Moving from xcode 12 to 13 produces the output below.

I have tried doing exactly what is says by specifying an explicit version in the podspec for the target but that doesnt help.

Showing my ignorance of the build process here, I guess, but can anyone tell me how to resolve this?

cheers

I am not experiencing this (using Xcode v13.3).

I have a few questions, which might help us diagnose this:

• What version of React Native are you using here?
• Does your app have a direct dependency on GCDWebServer?
• Did you do "the usual" dance of clearing build folder (from within Xcode), perhaps deleted the Pods and ran pod install, etc.?

[stefoid]

Hi - actually this is built using 'microsoft app center' which always builds from a clean slate.

RN is 63

Ill search for what else uses it and get back to you

[stefoid]

Hmm, not sure how to find out where it is being pulled in, other than Realm. npm list fails to reveal anything. I wouldnt be surprised if it was something like segment/analytics or the newrelic agent we are using

[stefoid]

@kraenhansen

As far as I can see, Realm is the only package depending on GCDWebServer. If I remove realm from the package list, GCDWebServer disappears as a target from my Pods directory.

In the build log, it is complaining: 2022-03-28T22:41:02.5152340Z note: Target 'GCDWebServer' (in project 'RealmReact') 2022-03-28T22:41:02.5253740Z note: Target 'GCDWebServer' (in project 'Pods')

so if GCDWebserver is a target in project Pods and project RealmReact, and Realm is responsible for it being in the Pods project, is it somehow the cause of this issue all by itself?

[jdl7758258]

same problem

[stefoid]

@jdl7758258 when you say the same problem, you mean build fails in 'App Center' or just in general?

For whatever reason, although xcode complains about the multiple dependency, it still compiles - it doesnt stop the build with a 'multiple commands produce...' error.

I mean, it would be ideal if Realm didnt produce dual dependencies for the library. Has anyone got a suggestion for how to address this in the podfile or whatever?

In the meantime, Ill see what I can do with App Center. Perhaps in the way of ignoring certain errors or similar

[kraenhansen]

As a workaround you could start using the "hermes" releases, it doesn't have a dependency on GCDWebServer:

npm install realm@hermes

[stefoid]

@kraenhansen Good to know thats an option, thx

[timppa23]

I can produce a similar problem by following this tutorial https://www.mongodb.com/docs/realm/sdk/react-native/install

Command

/Users/michael/.rbenv/versions/2.7.4/bin/pod install

I can also confirm that @kraenhansen 's proposed solution works.

[Pingou]

Same issue here, and building works but not archiving. I do not wish to use hermes for now. Any solution?

[Pingou]

Was able to archive by removing GCDWebServer from libraries -> RealmReact.xcodeproj -> targets -> GCDWebServer. Not sure of the whole implications but the app works for me.

[kneth]

We have removed GCDWebServer in version 11.0.0 and suggest that you use Flipper to debug.
