I am trying to localize my iOS app. However, I do not have translations for all the languages supported by Apple. I have translations for French and Dutch, with English as the base language. I wanted to know the common behavior in the following scenario. Suppose I set the iPhone language to French and then navigate to the app. I am able to correctly see all the translations. Now, I set the iPhone language to Portuguese. Now when I navigate to the app and I see the translations are still in French and not in English (the base language of my app). Is this behavior right? Shouldn't the language be set to English?
