Firebase-ios-sdk: Do not building iOS app - Firebase doesn't find FirebaseCore.h

[itsector-esanti]

[REQUIRED] Step 1: Describe your environment

• Xcode version: 11.3.1
• Firebase SDK version: 6.16
• Firebase Component: Core, Messaging, Analytics
• Installation method: CocoaPods

I am facing with a big problem to use Firebase pod.

It isn't allow me to build my pipeline on Azure DevOps.

Basically, when I try #import <Firebase/Firebase.h> in AppDelegate.m, that pod doesn't find FirebaseCore.

Use can see better in image that I have attached here.

P.S: I needed to hidden some important informations about my project on image. Sorry

[ryanwilson]

Hi @itsector-esanti sorry for the trouble - can you please post the Podfile.lock and Podfile you have so we can see what's being pulled in? Another thing to confirm - are you using the generated .xcworkspace for the project or the .xcodeproj instead? With CocoaPods you should be using the .xcworkspace.

[itsector-esanti]

Hello @ryanwilson

Here are my files...

Yes, I am using .xcworkspace.
files.zip

[ryanwilson]

I used the same Podfile setup (changing the name to my target's name), ended up with the exact same Podfile.lock (minus the Podfile checksum for the naming reason) and was unable to reproduce this.

Can you reproduce it locally in your project?

[rizafran]

Hi @itsector-esanti, as per docs, it's not needed to include pod 'Firebase/Core' in your Pod file.

Hi @ryanwilson I was able to reproduce it, but it works well when I removed the pod 'Firebase/Core'.

[ryanwilson]

Hmm, including or excluding Firebase/Core shouldn't make a difference.

Firebase/Core just points to FirebaseAnalytics and Firebase/CoreOnly, and Firebase/Analytics internally points to Firebase/Core so it should bring in the exact same set of dependencies.

I'll try to repro again.

[ryanwilson]

@itsector-esanti I chatted offline with @rizafran and afterwards we were both unable to reproduce the issue.

Is it possible that the target name is different from the xxxxxx Private you had put? It could be that the pods are being included for a different target than you're trying to include.

It'd also be helpful to know if you can reproduce this locally or it's just in CI.

Thanks!

[itsector-esanti]

@ryanwilson I'll remove Firebase/Core from my Podfile and try build it locally again.

As soon as possible, I write my results here.

[itsector-esanti]

@ryanwilson I removed Firebase/Core and tried again, but I got the same error in my CI.

About run it locally, I got the same problem too

[itsector-esanti]

I don't know if for you it's important, but I'm running that workspace with configured Build System as Legacy Build System. And about it, in my pipeline I'm using -UseModernBuildSystem=NO as parameter

[ryanwilson]

Hmm, I just tried with the Legacy Build System as well and was unable to reproduce (thanks for mentioning it though, definitely could have been the cause).

Are you able to reproduce it with our quickstart applications as well? If not, sounds like it's a project specific setup that's causing the issue. If you could share a simplified project it would be great for us to be able to debug!

[itsector-esanti]

@ryanwilson I just (unfortunately) can share with you some paths, configs for example...

Let me know if it can help you!

[ryanwilson]

Since you can't share your project (no worries, it's understandable 😄) if you could reproduce it with one of our quickstart applications (found at https://github.com/Firebase/quickstart-ios) that would be very helpful (and would allow you to share it). It should also give us an idea whether or not it's specific to your project or a larger issue.

[itsector-esanti]

@ryanwilson Yes I can do it.

Just to confirm, Would you like that I use my Podfile into that quickstart project?

[ryanwilson]

Thanks! Sure, having similar contents would be great and a higher likelihood of reproducing the issue. Please make sure to update the name of the target in the Podfile as well to match the quickstart app.

[itsector-esanti]

@ryanwilson let me make a question

What is the diference for Firebase with there imports below?

@import Firebase; vs #import <Firebase/Firebase.h>

[morganchen12]

The imports are equivalent if you have clang modules enabled. Clang modules are enabled by default.

[itsector-esanti]

People, I tried to build the AnalyticsExample using exactly the same Podfile that I am using into my project and I got again the same error 😞

I am attaching here a printscreen and .zip with AnalyticsExample.

This one was my command line: xcodebuild -sdk iphoneos -configuration Enterprise -workspace AnalyticsExample.xcworkspace -scheme AnalyticsExample build -UseModernBuildSystem=NO | xcpretty -r junit --no-color

analytics.zip

[ryanwilson]

Thanks for working with us on this.

Can you please copy what the error is without xcpretty? I downloaded the project, had to massage a few things (there were some shared resources in the parent directory that I didn't know about, I just removed them from the project and changed the LaunchImage) and ran the project to get the same error as you did with the command given. I then avoided piping the results into xcpretty and it was a code signing issue I had, not a Firebase issue. I fixed the code signing issue by changing the Provisioning Profile used, then the build command succeeded for me both from the command line and from Xcode itself.

[itsector-esanti]

I ran the same command line without xcpretty in my project and I got this:

Hi @itsector-esanti, I also tried to replicate the issue using the mcve you provided, but similar to @ryanwilson, I can't seem to reproduce it on my end.

To isolate the issue, could you try to rebuild your sample project, add code signing (to remove the error displayed on this previous comment) and see if the issue persists?

If so, maybe could you try cleaning the Cocoapods cache, try a new project with just Firebase in it, and see how far you can get without it failing?
