We are about to release a new version of our app an it would be great if we 
could support Bitcode via Cocoapods. This is the only library left now so can 
we get an update on a new Cocoapods release?

I Tried to update without any luck
https://github.com/CocoaPods/Specs/blob/master/Specs/GoogleAnalytics/3.13.0/Goog
leAnalytics.podspec.json

Whats weird :
- Dont' know where that archive referenced in podspec is coming from : (3.13)
  https://www.gstatic.com/cpdc/9b1bb5e186325dc2-GoogleAnalytics-3.13.0.tar.gz (814k)
- Archive : 3.13 SDK is 6.9 MB and the new 3.14 is 19.5 MB (what happened here 
?)
- libGoogleAnalyticsServices.a : 3.13 is 12.4 MB - 3.14 is 34.4 MB ! 
- Cocoapods 3.13 is using libGoogleAnalytics.a which doesn't exists in their 
SDK's probably because of "This is a combined SDK that includes both the Google 
Analytics SDK
and the Google Tag Manager SDK."

I will re-open this issue until the Google Analytics Cocoapod with 3.14 is 
released. We anticipate this to be made available in the coming weeks. I cannot 
give any concrete timeline but this is something we are actively working on.

Keep in mind that for iOS application bitcode is still optional. And if you are 
using the top level Google Cocoapod with any libraries that have yet to support 
bitcode you will still need to disable bitcode for you iOS application.

I will update once this thread once the Cocoapod  with the 3.14 library is 
available. We appreciate your patience.

is not optional if you support watchOS... I can't release my app because of 
this library... :(

Original comment by arielaaa...@gmail.com on 3 Nov 2015 at 7:11

GoogleCodeExporter commented 8 years ago 
As long as you don't include the google analytics library in your watchOS 
target, you can leave bitcode on for the watch. Then on the iOS target turn off 
bitcode.

This way you can submit your app which includes watch and analytics in the 
phone.

The changlog only mentions "Added support for bitcode." but the download size 
increased from 6.9MB to 19.5MB?  The library goes from 12.4MB to 34.4MB?  That 
feels like a large jump.  Why is it so large?

Original comment by wredskin...@gmail.com on 3 Nov 2015 at 10:37

GoogleCodeExporter commented 8 years ago 
Hello W,
This is due to bitcode. The increase in size is due to the fact that bitcode is 
an intermediate (not-fully compiled) representation of the code. Developers 
will see this increase in their own app code as well with bitcode enabled, 
regardless of what libraries you include.

However, what the end user downloads from the app store is much smaller. Apple 
does not ship the bitcode to users.

For comparison, the Paypal SDK went from 12MB to 120MB  with bitcode enabled 
(https://github.com/paypal/PayPal-iOS-SDK/releases).

Just want to make a quick comment here.  The delays for critical features are 
unacceptable.  As a developer and founder, I'm not leaving any chance when it 
comes to getting my features out the door.  I decided to abandon Google 
Analytics for Flurry, and it has been smooth sailing since.

Please add bitcode support. This is not acceptable, since bitcode is now a 
requirements from Apple:

XCode 7.1 Release Notes - Bitcode:

Bitcode

Apps that include incorrectly-built bitcode in frameworks and libraries are 
rejected by the App Store.
If you are a provider of framework and library products for iOS, watchOS, and 
tvOS platforms, your products must include full bitcode content. The Xcode 7 
build system defaults include enabling the Enable Bitcode build setting, but 
standard Debug or Release builds do not include the full bitcode content in the 
built framework and library products.

To build framework and library products for distribution and ensure that the 
full bitcode content is included, framework and library providers must:

Ensure that the Enable Bitcode build setting is correct (ENABLE_BITCODE=YES).
Perform either an Archive build or an Install build to produce framework and 
library products for distribution.

Good news everyone. The Cocoapods have now been updated to use The Google

Newbie here, I'm still getting the Bitcode error after updating to 3.14.0 (via 
pod update):

ld: '/Pods/GoogleUtilities/Libraries/libGTM_NSData+zlib.a(GTMNSData+zlib.o)' 
does not contain bitcode. You must rebuild it with bitcode enabled (Xcode 
setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable 
bitcode for this target. for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

And my pod file:

pod "Google/Analytics"

And pod update:

Update all pods
Updating local specs repositories

Using GoogleAnalytics (3.14.0)
Using GoogleInterchangeUtilities (1.1.0)

Using GoogleUtilities (1.1.0)

Did i do something wrong?

Original comment by zenk...@gmail.com on 10 Nov 2015 at 11:13

GoogleCodeExporter commented 8 years ago 
That is because you are using top level pod "Google/Analytics".  Which is tied 
to the state of greater Google pod. See comment 96 above. If you are only using 
the Google Analytics  component of that pod you should be able to use rebuild 
with GoogleAnalytics https://cocoapods.org/pods/GoogleAnalytics.

Ah I see. I saw the comment 96 but wasn't aware the difference between 
"Google/Analytics" and "GoogleAnalytics". Silly me.

Thanks for the quick reply.

You will also have to follow the initialization method listed here... 
https://developers.google.com/analytics/devguides/collection/ios/v2/     

The latest instructions are going to give you a headache because it references 
utilities not included in the pod.  Below will fail with the cocoapod

// Configure tracker from GoogleService-Info.plist.
NSError *configureError;
[[GGLContext sharedInstance] configureWithError:&configureError];
NSAssert(!configureError, @"Error configuring Google services: %@",

In local it works fine, but I have a problem in Jenkins. It takes hours to 
figured it out

Replace this in your pod file
pod 'GoogleAnalytics'

In your Bridging-Header.h (I use Swift)
#import "GAI.h"
#import "GAIDictionaryBuilder.h"
#import "GAIFields.h"

Add User headers search paths for both build and test target
$(SRCROOT)/Pods/Headers with recursive

Now I can sleep

GoogleCodeExporter commented 8 years ago 
Work around with GoogleAnalytics pod along with a Bridging Header to import the 
headers works but it's not perfect.  For instance now GA needs to be compiled 
along with any test targets too.

Can we please get an update on the actual Google/Analytics pod to use bitcode 
already?  It's been over 4 months since the official release of Xcode 7 and 
Bitcode was announced in beta about 7 months ago.

Any update on bit code support in the library ? It's been a long time since 
Xcode 7 came out.

Original comment by i...@thelocalite.in on 2 Feb 2016 at 8:33

GoogleCodeExporter commented 8 years ago 
If you are using cocoapods, you can add this at the end of the Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['ENABLE_BITCODE'] = 'NO'
    end
  end
end

This will recurse through all the pods and mark the ENABLE_BITCODE off. 
Naturally, you will not be able to compile for the watch / apple tv (as they 
require it on some versions).
