"duplicate symbols" related to AFNetworking

[hughknaus]

I upgraded from 1.1.0 to 2.0.7 for Android. I'm now working on upgrading the iOS side from cordova-ios@5.1.1 to cordova-ios@6.2.0. cordova-plugin-background-upload@2.0.7 has a requirement to install cocoapods, which required an upgrade in ruby for us. I also installed rubygems for bundler and fastlane. The iOS build results in "duplicate symbols" errors:

I found that cordova-plugin-advanced-http is currently referencing the AFNetworking (albeit renamed to SM_AFNetworking) and the imports in this plugin might be causing the "duplicate symbols", has anyone else ran into this and found a resolution? Cross reference issue on cordova-plugin-advanced-http: https://github.com/silkimen/cordova-plugin-advanced-http/issues/435

Additionally, when I remove cordova-plugin-background-upload from my app I can build without getting the "duplicate symbols" errors (of course that is undesirable as we do need the functionality for background uploading).

Hello @hughknaus,

We have a forked version of cordova-plugin-advanced-http. We also got some problems regarding AFNetworking. You can try to use this PR in your build: https://github.com/spoonconsulting/cordova-plugin-advanced-http/pull/3

@zafirskthelifehacker Thank you, I'll give it a try today.

@zafirskthelifehacker with https://github.com/spoonconsulting/cordova-plugin-advanced-http/pull/3 we were able to get a build and the app runs! A step in the right direction. We have to do some additional testing to do on our side but it definitely looks promising! Thanks again.

Hello @hughknaus,

Great to hear that. After you complete the tests, can you try to merge this PR(https://github.com/spoonconsulting/cordova-plugin-advanced-http/pull/3) on the base repository(https://github.com/silkimen/cordova-plugin-advanced-http)?

Thanks.
