One of the niggles with Unity https://unity.com when creating multi-language projects is the exported XCode project doesn’t export the configuration that enables additional languages in your project localisation resulting in possible automatic rejections when validating for upload to AppStoreConnect.

A fellow developer asked for help with his current gaming project as their localised and translated version of the game was being rejected with incorrect configuration.

Ordinarily you should be able to export your project, build in XCode and submit without needing to delve into XCode configuration.

It turns out this is still a common issue today in 2021, thankfully the fix is straight forward. If you’re experiencing this (you’re not alone), then take a look at the video I created a couple of years ago to help you on your way to App Store fame and fortune.
