CocoaPods could not find compatible versions for pod "Firebase/Crashlytics"

Question

I am developing react-native app.

I followed the firebase instruction adding my iOS app to my firebase project.

In my Podfile, I have:

pod 'Firebase/Crashlytics'
pod 'Firebase/Analytics'

when I run pod install I keep getting the error saying "CocoaPods could not find compatible versions for pod "Firebase/Crashlytics".

Xcode version 11.7, target iOS10.1

Why I get that error and how to get rid of it?

(I tried run pod update 'Firebase', I get:

[!] The Firebase Pod is not installed and cannot be update)

Run pod update Firebase to update all Firebase pods. – Ardin

I updated my question, I actually tried that, with and without the quotation mark, same error The 'Firebase' Pod is not installed and cannot be update. Also tried adding the pod 'Firebase/Core' , no luck either. – Tjirebon

Make sure that your project's minimum deployment target is at least iOS 9 (see Firebase/Crashlytics release notes) If that's OK, then try first to update the cocoapods spec repo by running pod repo update and then pod install. – Inhambane

Thanks, in xcode I have target iOS 10.1 but it is a react native project on the upper layer I am not sure in react-native is there a place to set the target or is it enough I only make sure xcode project use iOS 10.1. Anyway, target is 10.1 in xcode project. – Tjirebon

Check your Podfile file in your project root. It should have something like platform :ios, '10.1'. – Inhambane

Good point! I checked my Podfile, it is ios9.0 there. I thought xcode target value would automatically be applied to Podfile, but seems not... – Tjirebon

@Inhambane could you please make an answer? That solved my issue. And if possible it would be nice if you could give a few words about the platform version in Podfile is not associated with the xcode target version. – Tjirebon

Please do not show images of text. Copy the text into the question so it's easy to read, copy, and search. – Validate

In such cases You must try to use lower version for that library and then install pod... This will fix issue. This process helped me. – Heteropolar

Answer 1

Make sure that your project's minimum deployment target (the one that referenced in your Podfile) is at least iOS 9 (see Firebase/Crashlytics release notes)

Unfortunately when cocoapods initially create the Podfile, doesn't take into account your projects minimum deployment target. Instead adds a default value in a comment.

The first time that you run pod install you will get a warning about not specified minimum deployment target. Also cocoapods documentation doesn't mention anything regarding this behavior.

So, you have to have to manually edit your Podfile and add something like this:

platform :ios, '10.1'

Inhambane

@Heteropolar what error are you getting? Could you provide your project configuration? (deployment target, Podfile) – Inhambane

@Heteropolar minimum deployment target of Firebase/Crashlytics seems to be covered by iOS 10.1. (just tested) Maybe you have other conflicts in dependencies. Maybe you didn't add this line at the root of your Podfile or maybe 10.1 isn't the minimum deployment target of your project. I can't really help if you don't share more info. – Inhambane

Answer 2

In my case

pod install

threw an error:

[!] CocoaPods could not find compatible versions for pod "Firebase/Crashlytics":
  In snapshot (Podfile.lock):
    Firebase/Crashlytics (= 10.15.0)

  In Podfile:
    Firebase/Crashlytics

    firebase_crashlytics (from `.symlinks/plugins/firebase_crashlytics/ios`) was resolved to 3.4.3, which depends on
      Firebase/Crashlytics (= 10.16.0)

Specs satisfying the `Firebase/Crashlytics, Firebase/Crashlytics (= 10.15.0), Firebase/Crashlytics (= 10.16.0)` dependency were found, but they required a higher minimum deployment target.

So I had to execute the following commands, then it worked:

pod repo update 
sudo gem install cocoapods

and then again

pod install

Answer 3

No issue with the deployment target but got the same error. It was working with the following versions of Firebase

 pod 'Firebase/Core', '~> 3.0.0'
 pod 'Firebase/Crashlytics', '~> 7.0.0'

When I added a new dependency and run pod install, It was showing the error for Firebase. So, I used the >= 0 in place of the version.

pod 'Firebase/Core', '>= 0'
pod 'FirebaseCrashlytics', '>= 0'

This will install the latest version for all Firebase dependencies.
