How to change the language in Facebook-Account-Kit for iOS?
Facebook said that: Localization support is also provided by the SDK. The supported languages are packaged with the SDK. You don't need anything else to display text in the appropriate locale.
But it's not enough, you must add your language in Project Info like image below
I just change the simulator/device language. The display language on AccountKIT UI will be changed automatically . It worked for me
I also don't need to add localization config as "Thành Ngô Văn" answer
I had changed the device language. Now working fine.
