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 '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

Answer 1

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

Answer 2

try below commands:

pod repo remove master
pod repo update
pod install --verbose

Answer 3

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)

Answer 4

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

Answer 5

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

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

I hope it will help somebody.

Answer 6

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

Hope that helps

Answer 7

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.

Answer 8

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

sudo gem install cocoapods
pod repo update
