CocoaPods could not find compatible versions for pod "GTMSessionFetcher/Core"

[atif-infinityup]

I am using Google SignIn Plugin version 1.0.4 Upgraded and Firebase Authentication (Version: 10.3.0) for Google SignIn on IOS using unity version 2021.3.16f1.
Unity is unable to make Xcode project properly.
Showing Error
"iOS framework addition failed due to a CocoaPods installation failure. This will will likely result in a non-functional Xcode project."

Then I tried to install pod from terminal the issue remains the same.

So basically pod is unable to find correct GTMSessionFetcher/Core file due to conflict between two requirements.
Is there any way to increase GTMSessionFetcher/Core (~> 1.1) value ?

Morning I just had this same problem. I have managed to work around this by manually modifying the locally install PodSpecs to use a newer version of GTMSessionFetcher/Core that matches FirebaseAuth.

Find the location of the GoogleSignIn podspec file. Mine was at "/Users/{user}/.cocoapods/repos/cocoapods/Specs/d/4/0/GoogleSignIn/5.0.2/GoogleSignIn.podspec.json"

and change "GTMSessionFetcher/Core": "~> 1.1" under dependencies to "GTMSessionFetcher/Core": [ ">= 2.1", "< 4.0" ]

this will make it match the FirebaseAuth podspec and the xcode workspace will be correctly created .

Any one fix this issue ?
@atif-infinityup can you tell me how you fix this issue ?

I can't understand why this plugin not update since 2018 !!

Although downgrading firebase to 9.6.0 will fix it..

I would definitely just do the fix @ChrisBindy mentioned.
I think staying up-to-date is more important as there are many bug fixes in latest versions

I have found a solution:
#228 (comment)

[N4TUR1NO]

and change "GTMSessionFetcher/Core": "~> 1.1" under dependencies to "GTMSessionFetcher/Core": [ ">= 2.1", "< 4.0" ]

ChrisBindy is any other actions required? i changed dependencies like you said and nothing happens ;(

@N4TUR1NO Heya, unfortunately I don't work with Unity anymore so I'm unsure of the fix, I hope you mange to get it sorted

I found same folder in trunk (from: cocoapods/repos/trunk/Specs/d/4/0/GoogleSignIn/6.0.2(my version)) and worked for my case. don't forget the edit main file like upper comment.

my pod file is:

source 'https://cdn.cocoapods.org/'

platform :ios, '13.0'

target 'UnityFramework' do
pod 'FBSDKCoreKit', '> 16.0.1'
pod 'FBSDKCoreKit_Basics', '> 16.0.1'
pod 'FBSDKGamingServicesKit', '> 16.0.1'
pod 'FBSDKLoginKit', '> 16.0.1'
pod 'FBSDKShareKit', '> 16.0.1'
pod 'Firebase/Analytics', '10.25.0'
pod 'Firebase/Auth', '10.25.0'
pod 'Firebase/Core', '10.25.0'
pod 'Firebase/Messaging', '10.25.0'
pod 'GoogleSignIn', '> 6.0.2'
end
target 'Unity-iPhone' do
end
