xcode - Error installing google analytics on iOS app -

i trying integrate google analytics project, , surprised requires cocoapods install google analytics now.

i followed documentation here:

https://developers.google.com/analytics/devguides/collection/ios/v3/?hl=en

i called pod init on terminal, , i've edited podfile to

# uncomment line define global platform project  # platform :ios, '6.0'    target 'unity-iphone'  pod 'google/analytics', '~> 1.0.0'  end    target 'unity-iphone tests'    end

and following error on terminal when call pod install.

updating local specs repositories analyzing dependencies [!] unable find specification google/analytics (~> 1.0.0)

[!] cocoapods not able update master repo. if unexpected issue , persists can inspect running pod repo update --verbose

it did not generate .xcworkspace file.

how can fix issue?

edit:

i tried answer steffen setup master repo again, , error now.

analyzing dependencies [!] unable satisfy following requirements:

• google/analytics (~> 1.0.0) required podfile

although podfile still contains pod 'google/analytics', '~> 1.0.0'

i had problem on os x el capitan version 10.11.5

1. open terminal command prompt

2. path xcode project folder

   $ cd /path/to/xcode/myproject/ 

3. create podfile using command

   $ pod init 

4. add line pod 'google/analytics' generated podfile

     # uncomment line define global platform project      # platform :ios, '8.0'      # uncomment line if you're using swift      # use_frameworks!       target 'myproject'       pod 'google/analytics'      end 

5. try install pod fails

   $ pod install -bash: pod: command not found 

6. try install cocoapods fails

   $ sudo gem install cocoapods  error:  error installing cocoapods: activesupport requires ruby version >= 2.2.2. 

7. you need install activesupport lets install cocoapods okay pod install fails new bug

   $ sudo gem install activesupport -v 4.2.6 $ sudo gem install cocoapods $ pod install [!] unable find specification 'google/analytics' 

8. perform these last steps , pod install succeed

   $ pod repo remove master $ pod setup $ pod install 

nb of these command line actions take long time complete , terminal gives no indication doing anything, appears broken working quietly therefore needs patience.

so sad still have resort command line in 2016
