Cocoapods: Unable to find a specification for `Firebase/Core`

Question

I have this in podfile:

pod 'Firebase/Core'
pod 'Firebase/Messaging'

but getting this error:

[!] Unable to find a specification for Firebase/Core

i tried with pod 'Firebase' still can't find it.

Podfile:

# Uncomment this line to define a global platform for your project
# platform :ios, '8.0'
# Uncomment this line if you're using Swift
use_frameworks!

target 'caffetouch manager' do
    pod 'Firebase/Core'
    pod 'Firebase/Messaging'
    pod 'Alamofire', '~> 4.0.0'
    pod 'AlamofireNetworkActivityIndicator', '~> 2.0.1'
    pod 'IQKeyboardManagerSwift', '~> 4.0.6'
    pod 'MZFormSheetPresentationController', '~> 2.4.2'
    pod 'Kingfisher', '~> 3.1.3'
    pod "GMStepper"
    pod 'DKImagePickerController', '~> 3.4.0'
    pod 'Siren', '~> 1.0.2'
    pod 'Eureka', '~> 2.0.0-beta.1'
    pod 'SwiftyJSON'
    pod 'ObjectMapper', '~> 2.1'
    pod 'NVActivityIndicatorView'
    pod 'SwiftDate', '~> 4.0.5'
    pod 'SimpleAlert' '~> 2.0.1'

    pod 'BTNavigationDropdownMenu', :git => 'https://github.com/PhamBaTho/BTNavigationDropdownMenu.git', :branch => 'swift-3.0'
    pod 'ENSwiftSideMenu', :git => 'https://github.com/evnaz/ENSwiftSideMenu.git', :branch => 'master'
    pod 'SkyFloatingLabelTextField', git: "https://github.com/MLSDev/SkyFloatingLabelTextField.git", branch: "swift3"
end


post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '3.0'
    end
  end
end

Try to update pod repository

pod repo update

If doesn't help show log from

pod install --verbose

Edit:

try to add

source 'https://github.com/CocoaPods/Specs.git'

to your Podfile. If doesn't help probably there is a problem with your local pod repo. You can fix this using:

pod repo remove master
pod setup
pod install

Genius - the last set of instructions solved the issue. Might have had something to do with Unity attempting to setup pods before I had a chance. – fionbio Oct 31 '17 at 10:38
I also ran into this situation and fixed it by removing `Pods` and `Podfile.lock` then re-running `pod install` – JaredH Feb 01 '18 at 18:57
Yeah, sometimes it helps. If you remove `Pods` folder and `Podfile.lock` you can also remove `workspace` file. It will be generated again – Piotr Labunski Feb 01 '18 at 19:11

@Siva What do you mean by "add the source in the terminal"? – Piotr Labunski Jan 26 '22 at 08:07

try to delete the file podfile.lock
it helps with issue:

[!] CocoaPods could not find compatible versions for pod "Firebase/Core":
In snapshot (Podfile.lock):
Firebase/Core (= 4.8.1)

could you also please write what exactly deleting the lock file does? Can it have any side effects? – Alexander Sep 11 '18 at 15:42
deleting pod lock file could potentially break project and might be catastrophic, as newer versions of pods might have changed. Doing this requires proper migration for each of the updated pod. – Aamir Oct 26 '18 at 09:47

Check if your podfile looks like this and then execute pod install:

platform :ios, '10.0'
use_frameworks!

target '<YOUR APP TARGET>' do

  # Firebase
  pod 'Firebase'
  pod 'Firebase/Core'
  pod 'Firebase/Messaging'

end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '3.0'
    end
  end
end

This worked for me by updating cocoapods and my pod repo:

sudo gem install cocoapods
pod repo update

None of the approaches mentioned worked for me. Here is how I made it to work, however:

Comment out all of your pods in your Podfile.
Comment them back in one-by-one and run pod install after each
Clean and run

I hope it will help somebody.

If it still doesn't work, remove cocoapods directory rm -rf ~/.cocoapods and re-setup cocoapods using pod setup

Hope that helps

Yes. If your cocoapod git repo is bad. This will work. Because my repo was not getting updated. – ajpaul Mar 06 '18 at 20:39

had the same problem.

what really worked for me was gem uninstall cocoapods where I found that I had 11 (!) cocoapods versions. I chose to uninstall all and then gem install cocoapods:1.4.0

All good now.
