IAP Entitlement issue on iOS Enterprise builds

[sametguzeldev]

Hello there!

I have noticed that when we enable to add StoreKit framework from Adjust settings, it adds the StoreKit framework into Unity Main Target which causes it to also add In App Purchase entitlement into the xcode project. But In App Purchases don't work on Enterprise builds and our enterprise profile does not have IAP entitlement therefore cannot make a build.

I assume StoreKit is needed for SKAdNetwork.registerAppForAdNetworkAttribution(), not really for IAPs.

So instead of adding StoreKit to main target, can't we add it to UnityFramework instead? That way we link the framework where Adjust is being built anyway. Also it will not add the entitlement as well. I tested this with Unity 2022.3.53f1

I changed this line;
xcodeProject.AddFrameworkToProject(xcodeTarget, "StoreKit.framework", true);
with this;
xcodeProject.AddFrameworkToProject(xcodeProject.GetUnityFrameworkTargetGuid(), "StoreKit.framework", true);

Had no issues so far.

Hey @sametguzeldev,

Thanks for reporting this. Very interesting. The change you made is perfectly fine and makes sense. We'll be looking into adding something to support this use case in the future Unity SDK releases.

Simple change like you did might not do the trick on our end since then we will be linking all the frameworks to UnityFramework target for everyone next to having it linked to Unity-iPhone target, which might not be something everyone will be happy with. On your end it's fine since you're aware of the change and you are manually removing StoreKit.framework from your Unity-iPhone target.

We'll look into finding ways to make this change backwards compatible and I'll keep you posted when we come up with some support for this use case.

Cheers
