# Do’s and Don’ts

* **Search the solutions in the [troubleshooting guide](https://guides.cocoapods.org/using/troubleshooting.html).** Or any of the many other [guides](https://guides.cocoapods.org).
* **Search tickets before you file a new one.** Add to tickets if you have new information about the issue.
* **Only file tickets about the CocoaPods tool itself.** This includes [CocoaPods](https://github.com/CocoaPods/CocoaPods/issues),
  [CocoaPods/Core](https://github.com/CocoaPods/Core/issues), and [Xcodeproj](https://github.com/CocoaPods/Xcodeproj/issues).
  If your question is regarding a library (to be) distributed through CocoaPods, refer to the [spec repo](https://github.com/CocoaPods/Specs).
  If your question is “How do I […]”, then please ask on [StackOverflow](https://stackoverflow.com/search?q=CocoaPods) or our [mailing-list](https://groups.google.com/group/cocoapods).
* **Keep tickets short but sweet.** Make sure you include all the context needed to solve the issue. Don't overdo it. Great tickets allow us to focus on solving problems instead of discussing them.
* **Take care of your ticket.** When you spend time to report a ticket with care we'll enjoy fixing it for you.
* **Use [GitHub-flavored Markdown](https://help.github.com/articles/markdown-basics/).** Especially put code blocks and console outputs in backticks (```` ``` ````). That increases the readability. Bonus points for applying the appropriate syntax highlighting. (Tip: Podfiles are written in a Ruby DSL.)
* **Do not litter.** Don’t add +1’s _unless_ specifically asked for and don’t discuss offtopic issues.
* **Spell the name of the project correctly.** It's CocoaPods. In upper camel case.

## Bug Reports

In short, since you are most likely a developer, provide a ticket that you _yourself_ would _like_ to receive.

We are **not** here to support your individual projects. We depend on _you_ (the community)
to contribute in making the tool better for everyone. So debug and reduce your own issues

Pratham_Hebbar:

CocoaPods : 1.10.0
        Ruby : ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin20]
    RubyGems : 3.0.3

       Xcode : 12.2 (12B45b)

OK that’s interesting. You have the same version of Cocoapods, Ruby and RubyGems as I do although you have macOS Big Sur whereas I still have Catalina.

If you are running a Mac with an M1 processor the issue may well be with Terminal insofar as it has to be run under Rosetta.

Follow the steps in the following article and see if that solves the issue.

Hi Chris,

I followed the steps in the article and that did not solve the issue.
I still can’t integrate the Firebase SDK into my xcode project.

Chris_Parker · December 8, 2020, 10:41pm

The first line of the terminal output in your earlier post is alluding to what might be the issue all along:

LoadError - dlsym(0x7ff927254990, Init_ffi_c): symbol not found - /Library/Ruby/Gems/2.6.0/gems/ffi-1.13.1/lib/ffi_c.bundle

There is a stackOverflow thread that suggests that you need to do the following:

sudo gem install ffi

Dumby · December 9, 2020, 6:15pm

Does that mean I have to uninstall the following or still keep it on my machine?

sudo gem install cocoapods

Chris_Parker · December 9, 2020, 10:31pm

No it’s an addition which should mean that your pod install will succeed.

Dumby · December 10, 2020, 2:29am

Thank you so much!
That really helped save the day!

Dumby · December 10, 2020, 5:54am

I really appreciate your time!

Dumby · December 22, 2020, 4:39am

have you tried typing in the command sudo gem install ffi in the terminal window before navigating to your xcode project directory from within the terminal window?
