Mediation fails to initialize on iOS with an exception

amjaliks · April 11, 2022, 11:51pm

Just integrated Mediation SDK in our project. It works fine in Editor. Runs on Android. However, fails with an exception on iOS:

NSInvalidArgumentException: +[UMISConfigurationResponse adNetworkFromAdNetworkName:]: unrecognized selector sent to class

Hi @amjaliks ,

Thanks for reaching out. Could you also share your Podfile and Podfile.lock from your generated iOS project?

Thank you,

DeclanMcPartlin · April 12, 2022, 1:04am

After a quick go at trying to reproduce your issue, I was quickly able to reproduce your issue. The most possible reason that this is occurring is because your target in Xcode doesn’t have the ‘-ObjC’ flag in the ‘Other Linker Flags’ section. In most cases that would be the UnityFramework target, and by default it should be there.

My question to you is, are you changing the xcodeproj file via script post build by any chance? Or is there any way you know of that would be changing the values of ‘Other Linker Flags’ ?

amjaliks · April 12, 2022, 10:33pm

Thanks! Indeed UnityFramework is missing the -ObjC flag.

Unfortunately, I can’t find why this flag is missing from our iOS builds.

From my attempts to understand what is going, this isn’t related to .pbxproj modifications. This flag should come from .xcconfig file created by CocoaPods. At least this how works when I create a new empty Unity project and add Mediation package to it.

DeclanMcPartlin · April 13, 2022, 3:37pm

Thanks for providing further insight into this. Generally it is Cocoapods that includes that flag into UnityFrameworks, right. Which version of Cocoapods are you using? If possible, let us know if you find out what is causing this scenario in your project if you get to the bottom of it, I’ll let you know if we are able to reproduce. Also, if you could share the Podfile of the generated Xcode project, that could help pinpoint the issue.

Thanks!

amjaliks · April 14, 2022, 5:51pm

The issue went away after adding an AppLovin adapter, as its podspec includes -ObjC definition.
Maybe the same should be done with a podspec for Unity Mediation SDK?

DeclanMcPartlin · April 22, 2022, 10:20pm

Hi @amjaliks ,

This is a known issue on certain Cocoapod versions, for example versions below 1.10.1. If you in fact do have such an older version, let us know if upgrading your Cocoapods version fixes the issue.

Thanks for sharing this issue with us!

amjaliks · April 29, 2022, 3:43pm

Yes, indeed I have used and older version of CocoaPods 1.9.1.
Updating to 1.11.3 seams to resolved the issue.

I haven’t done complete testing, however, a quick build of a Unity projects results in an Xcode project that has -ObjC flag set.

DeclanMcPartlin · May 5, 2022, 3:21pm

Thank you for confirm this with us @amjaliks , much appreciated.
