It's clear that Google is not really interested in improving/updating this 
library. Since version 3.0.8 at least it's been giving me problems in apps 
submission because it contained "unsupported or illegal" instructions. I had 
already switched to other analytics libraries out there, and I would definitely 
suggest you to do the same.

As slicing currently isn't working 
(https://developer.apple.com/news/?id=092415a&1443125762), why don't you 
disable bitcode for now and submit a new version of your apps later when Google 
has fixed analtycs?

Original comment by b...@brethansenfamily.com on 30 Sep 2015 at 6:39

[GoogleCodeExporter]

The closed source status of this project mixed with blatant disregard for 
modernization is very alarming. Regardless of the current status of app 
slicing, bitcode support is a matter of changing a single boolean before 
building. Both 64bit support and now bitcode took months and months of 
strongarming and threats from the community for them to finally cut a release. 
Apple gave us all half a year (even longer for arm64 support) to make these 
changes, and google can't even rebuild a static library with a single build 
setting change. 

Does anyone on the ios SDK team actually build ios apps? Maybe you can ask an 
intern to ENABLE_BITCODE=YES, and cut a new release? There is absolutely no 
reason we should be blocked on something like this right now. Are internal 
teams like inbox not using the GA client? Do they have access to internal 
source? I'm surprised other internal ios projects within google have not taken 
this issue into their own hands.

Hey guys (GA team),

I'm a completely new user to this library and I just wanted to let you know, 
due to the overwhelming warning here in this thread from responsible (+awesome) 
developers, I am steering clear of Google's entire iOS (Swift/Obj-C) offerings.

We are choosing not to use Cloud Messaging, Sign In, and the whole rest of it 
due to this issue. High priority does not even begin to cover it. RRoman above 
is correct - it's one simple build flag change and we're done with you over it.

Just to help the Google guys along, the Open Source community recently got 
CardIO's spec to work with Bitcode. If the GA guys are struggling they could 
follow the thread here https://github.com/card-io/card.io-iOS-SDK/issues/119 
and see how CardIO managed to resolve this.

Pretty disappointed at the utter lack of care in fixing this. It should have 
been done months ago. Given it's still outstanding, there should be an engineer 
working on this right now until it is released.

Maybe Google are moving out of the iOS mobile analytics game?  Or maybe their 
coder is taking a sabbatical away from coding....

Maybe the title of this issue needs changing to highlight that BITCODE is 
preventing Google Analytics being deployed to iOS app that support Apple Watch?

To submit watchOS 2 apps and still have GA in the project, all you have to do 
is enable bitcode for the watch app and watch extension targets, and disable 
bitcode for the iOS app target.

Out of all the companies' analytics I could have chosen to integrate into my 
game, I would have guessed that Google would have been the least likely to not 
keep theirs functional. Is it abandoned for iOS? If it is, or if there is no 
plan to update it, just let us know so that we can rid ourselves of it. Please 
give us some idea what is up...

For those people that were experiencing this issue in conjunction with Xcode 
7's code signing bug (caused by bitcode disabled in the parent, enabled in the 
child), I'm happy to report that after working through the Xcode issue via a 
radar, last night Apple instructed me to test against Xcode 7.1 beta 3, and 
that issue is resolved for me. I'd still like Google analytics to support bit 
code, but I am finally able to distribute via enterprise distribution profiles 
again.

We thank everyone for their patience as we are actively working to get the new 
SDK released as soon as possible. As work around it is possible to build and 
deploy projects that have the current Google Analytics SDK with bitcode 
disabled for iOS targets and with watchOS targets with bitcode enabled.

There is an example on stackoverflow on how to disable bitcode.
http://stackoverflow.com/questions/30848208/new-warnings-in-ios9

There there are also reports that the related xcode distribution profile 
signing issue for applications with this configuration is resolved with Xcode 
7.1 beta 3:

You can't, if you have another framework with bitcode enabled, for example 
google maps sdk ;-)
How long does it take to set a flag, rebuild and publish?

Original comment by jwolff....@googlemail.com on 13 Oct 2015 at 8:35

[GoogleCodeExporter]

Hello jwolf,
Thank you for writing in.

Integrating with one library that has bitcode doesn't make it a requirement for 
your entire application. As far as I am aware the Google Maps SDK has not yet 
enabled bitcode: 
https://code.google.com/p/gmaps-api-issues/issues/detail?id=8219

Also, I will update this thread with any news about upcoming release.

Original comment by mcoh...@google.com on 13 Oct 2015 at 11:03

[GoogleCodeExporter]

@mcoh: The problem is, that bitcode enabled frameworks are not delivered as a 
fat library, including all the architectures you need. And you are right, 
Google Maps is not bitcode enabled yet. I looked at the demo project, which was 
bitcode enabled because this is the XCode 7 dafault setting.

Thank you for updating :-)

Is there any known workaround to release iOS app with bit code enabled that is 
using Google Analytics?

With the latest cocoa pod for Google/Analytics (1.1.1) we are getting Xcode 
linker error when building for iOS Device:

Original comment by kostian...@rocketfarm.no on 21 Oct 2015 at 11:27

[GoogleCodeExporter]

@mcoh Can you give us a little more insight into this delay? It doesn't make 
much sense to most developers. My guess is that you guys are following an 
internal process that makes it difficult to release patches? Do you commit 
directly into master, which might explain this delay?  Did a major point 
release get caught in a merge process that is now making a simple rebuild take 
months? 

I understand why arm64 may have been a lot more involved because of very real 
migration issues, but the bitcode delay is still very alarming. Are you facing 
issues with Apple's toolchain? Is there some edge case, specific to how this 
library was implemented, that is making you jump through hoops? 

Any information would be great. 

Original comment by RRomanc...@gmail.com on 21 Oct 2015 at 8:00

[GoogleCodeExporter]

Hi Roman,
There are a number reasons for the delay, but largely it is because the 
underlying build infrastructure needed to be updated to support Xcode 7 while 
still maintaining support for legacy versions. And that change required a whole 
chain of dependencies to be fixed. There are also stringent quality assurance 
and testing procedures that ensure all the libraries will work once released. 
The team responsible for cutting the final release has assured me that a 
release is coming soon.

A note about the cocoapods: "GoogleAnalytics" will be updated soon with this 
latest release, and if you are using that directly you should be able to enable 
bitcode. But if you are using the "Google" pod, the top level library does not 
yet have bitcode enabled. But it is being worked on now as well.
