I have implemented localization Internally(To change language inside app) in app by using this github repo : ios_language_manager

While changing language from app (Not iPhone language) from English to Arabic it is not changing UITextFiled's placeholder text and value to RTL. But if I change the iPhone language to Arabic then it works perfectly.

Both of the below textfield's text alignment is natural from storyboard.
Without text input only placeholder text (Placeholder should come from right side)

With text input and floating placeholder (Text should come from right side)

If I change language from iPhone settings then it works perfectly.

Without text input only placeholder text (Perfect)
