Getting error Unrecognized font family 'din-next-lt-w23-regular' in react-native 0.61.4 only for iOS

i am using fonts in my app. So i need to add the font din-next-lt-w23-regular in my app. But i am getting error in iOS i.e., Unrecognized font family 'din-next-lt-w23-regular'. I added .ttf files in ios/Resources and info.plist. Here is my code react-native.config.js

module.exports = {
  project: {
    ios: {},
    android: {},
  },
  assets: ['./assets/fonts/'], 
};
