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 

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
