Empty Display Name on Xcode

Yes from what I can recall the value is in a different info.plist file.

 

You will need to manually edit the info.plist file to give it default values. We have fixed this in the next release.

 

You can't. You would need to modify the localization package code.
Move the localization package from the package cache into the projects Packages folder.
Now replace the script Editor/Platform/iOS/Player.cs contents with this:

Code (csharp):

1. #if UNITY_IOS || UNITY_IPHONE

Try updating to 1.4.3 which includes the fix for empty ios field names.
You may need to manually edit the manifest.json file in the Packages folder if its not visible in the package manager.

 

I thought you were having the same issue as this thread. If it's a signing issue then it doesn't sound related to localization. You will need to sign your app with a valid iOS developer license
