bug?: Cocoa Pods Conflict?

[EinfachHans]

Bug report

Current behavior:

I just added your Plugin to a new App and get this Error:

Failed to install 'cordova-plugin-firebasex': Error: pod: Command failed with exit code 1
    at ChildProcess.whenDone (/Users/hanskrywalsky/IdeaProjects/beat-the-virus/node_modules/cordova-common/src/superspawn.js:135:23)
    at ChildProcess.emit (events.js:311:20)

    at Process.ChildProcess._handle.onexit (internal/child_process.js:286:5)
pod: Command failed with exit code 1

After run pod install, i get this Error:

CocoaPods could not find compatible versions for pod "GoogleAppMeasurement":
  In snapshot (Podfile.lock):
    GoogleAppMeasurement (= 6.4.0, ~> 6.0)

  In Podfile:
    Firebase/Core (= 6.18.0) was resolved to 6.18.0, which depends on
      FirebaseAnalytics (= 6.3.0) was resolved to 6.3.0, which depends on
        GoogleAppMeasurement (= 6.3.0)

    Google-Mobile-Ads-SDK (~> 7.57) was resolved to 7.58.0, which depends on
      GoogleAppMeasurement (~> 6.0)

Specs satisfying the `GoogleAppMeasurement (= 6.4.0, ~> 6.0), GoogleAppMeasurement (~> 6.0), GoogleAppMeasurement (= 6.3.0)` dependency were found, but they required a higher minimum deployment target.

I have set my Deployment Min Target to 11:
<preference name="deployment-target" value="11.0" />

Google-Mobile-Ads-SDK comes from this Plugin: https://github.com/admob-plus/admob-plus

Can you help me out with this? Is there a Way i can handle this Issue?

This is a Pods version conflict between Google Mobile Ads SDK and Firebase SDK components pulled in by each plugin, as you can see from the error.

Google-Mobile-Ads-SDK (~> 7.57) (resolved to 7.58.0)  
	=> GoogleAppMeasurement (~> 6.0) 
		=> 6.4.0

Firebase/Core (= 6.18.0)
	=> FirebaseAnalytics (= 6.3.0)
    	=> GoogleAppMeasurement (= 6.3.0)
    		=> 6.3.0

So the loose version specification in Google-Mobile-Ads-SDK is pulling in 6.4.0 which conflicts with the exact version specification of Firebase as 6.3.0

Since the latest iOS release version of the Firebase SDK is 6.0.22, you can try forking this plugin and editing the plugin.xml to bump all teh 6.18.0 versions to 6.0.22 in the hope that a newer version of Firebase SDK pulls in a new version of GoogleAppMeasurement.

If this works, feel free to submit a PR and I'll merge the changes to this plugin to go out in the next release.

Thanks for your quick answer and explanation. I think i don't need to test this by forking. I found this where you can see that Version 6.22.0 depends on FirebaseAnalytics@6.4.1, which, as you can see here, depends on GoogleAppMeasurement@6.4.1.

So will this work then? Because one is 6.4.0 and one is 6.4.1?

[dpa99c]

~> 6.0 will resolve to the latest 6.x version so if you run pod repo update on your local machine to pull in the latest podspecs then bump to 6.22.0, it should work.

[EinfachHans]

should i create a pr for upgrading to 6.22.0 or do you?

[askona]

@dpa99c please increase version of plugin after pods update

[dpa99c]

@askona the plugin version will be increased when the next release is tagged and released to npm

[askona]

@dpa99c just FYI, for now 9.1.0 contains old pods - 6.18.0, which are conflicts with most of recent other plugins, whos using firebase

[EinfachHans]

Wait for the next Release, i think it will be published soon. As a alternative you can go into the plugins Folder and edit the Plugin.xml youtself. Remove the Platform and readd it

[askona]

Maybe this will be usefull for someone, I'm using npm command
"fix_firebasex_issue": "sed -i -e 's/6.18.0/6.22.0/' plugins/cordova-plugin-firebasex/plugin.xml",

[remisture]

When will the fix be released?

[dpa99c]

cordova-plugin-firebasex@9.1.1 has been published which resolves this

Hello, I believe this bug is present again with new higher versions. I get identical errors as initially reported, just with higher versions:
CocoaPods could not find compatible versions for pod "GoogleAppMeasurement":
In snapshot (Podfile.lock):
GoogleAppMeasurement (< 9.0, = 8.10.0, >= 7.0)

In Podfile:
Firebase/Core (= 8.4.0) was resolved to 8.4.0, which depends on
FirebaseAnalytics (~> 8.4.0) was resolved to 8.4.0, which depends on
FirebaseAnalytics/AdIdSupport (= 8.4.0) was resolved to 8.4.0, which depends on
GoogleAppMeasurement (= 8.4.0)

Specs satisfying the GoogleAppMeasurement (< 9.0, = 8.10.0, >= 7.0), GoogleAppMeasurement (= 8.4.0) dependency were found, but they required a higher minimum deployment target.

[stickoutapp]

By the way, will the fix also be available for the CLI version?

[stickoutapp]

Good news is that I have forked the plugin and bumped firebase version in plugin.xml from 8.4.0 to 8.10.0 and my project builds and works fine. Or more precisely firebasex functionality still works fine.. I have not tested admob yet. I have modified and tested CLI branch.

here is the change:
