[Bug] [iOS]Xcode13 duplicate symbol error

[haofanning]

The new iOS version plugin conflicts with AFNetworking. The error message is:

Hi @haofanning, could you get it to work? We also have AFNetworking being installed by another plugin and the build fails because of duplicate symbols.

[haofanning]

@azharbeebeejaun No,I cant make it work, so I have to use the old version of cordova-plugin-advanced-http.

[hughknaus]

I too am receiving 89 duplicate symbols for architecture arm64 errors and they do all appear related to AFNetworking when upgrading to cordova-ios 6.2.0 and cordova-plugin-advanced-http 3.2.2 (also tried downgrading to 3.0.0 but ended up with 157 duplicate symbols), however, I'm using Xcode 12.5:

@haofanning did you find a version of the plugin that worked?

[haofanning]

@hughknaus I have an old version locally that I downloaded earlier,It depend on AFNetworking.If you want this version,give me your email address,I can send it to you.

[hughknaus]

@haofanning what version of cordova-ios and cordova-android are you using with your old version of cordova-plugin-advanced-http?

[haofanning]

@hughknaus cordova-ios is newest version 6.2.0 , and I am not sure the version of cordova-plugin-advanced-http, sorry for that , maybe it's 3.0.0

[hughknaus]

@haofanning I was actually moving from 3.0.0 to 3.2.2 because I was getting the same "duplicate symbols" error (only more of them) and I was hoping 3.2.2 would help. I think this started because we had another cordova plugin that required build dependency changes, cordova-plugin-background-upload upgrade from 1.1.0 to 2.0.7 requires cocoapods, which caused us to have to install a newer version of ruby, followed that up with gem installs of bundle and fastlane . I was also trying to upgrade cordova-ios from 5.1.1 to 6.2.0, but I'm wondering if it has something to do with the build system...

[haofanning]

@hughknaus I think you are going in the wrong direction. I think this error is caused by a conflict between the AFNetworking library and newest version cordova-plugin-advanced-http, because the code of the AFNetworking library is used by the latest version of cordova-plugin-advanced-http, resulting in variable redefinition. So the solution is to roll back cordova-plugin-advanced-http to a historical version that does not use SM_AFNetworking or do not refer to AFNetworking when using cordova-plugin-advanced-http.

[haofanning]

@hughknaus Maybe AFNetworking's code is also used in cordova-plugin-background-upload, causing cordova-plugin-background-upload to conflict with cordova-plugin-advanced-http.

[hughknaus]

@haofanning Thank you for mentioning that... it's the one thing I didn't check! And it IS using AFNetworking!

[haofanning]

@hughknaus You are welcome

[hughknaus]

I noticed that this commit (c2a0317), with message of

replacing AFNewtworking file and classes names to prevent conflicts with the real AFNetworking pod

renames all the AFNetworking to SM_AFNetworking and the "duplicate symbols" errors that I get relate to SM_AFNetworking, and cordova-plugin-background-upload doesn't have references to SM_AFNetworking (but they import AFNetworking).

[haofanning]

@hughknaus That's why i say you can give me your email address, I have the iOS old version of cordova-plugin-advanced-http and it import AFNetworking too(not include SM_AFNetworking inside). I think it can solve your problem.

[hughknaus]

@haofanning I was using 3.0.0, it uses AFNetworking and I get even more "duplicate symbols" with it. From the commit (c2a0317) I imagine that's why they renamed it to SM_AFNetworking, but something else is causing the duplicates with it. I have found no good solution.

[haofanning]

@hughknaus OK then, that seems to work for me so far. Maybe you can find all SM_AFNetworking,make sure it doesn't exist in your project.

[hughknaus]

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

I know the files are named differently but the interfaces/implementations are named the same...

[haofanning]

I'm glad you found the cause of the problem, maybe we should let the maintainer know.

[hughknaus]

@haofanning the maintainer of cordova-plugin-background-upload has a fork and a PR of cordova-plugin-advanced-http that may just resolve the issue: spoonconsulting/cordova-plugin-background-upload#190 (comment)

[haofanning]

@hughknaus Great to hear that！Thank you for trying.

Will be fixed in v3.3.1 Thanks for providing the PR @zafirskthelifehacker! 👍
