{ fontWeight: '100' }, // Thin

{ fontWeight: '600' }, // Semibold
{ fontWeight: '700' }, // Bold

Thanks mate, helped a lot.

It helps a lot! Thanks!

export const fontWeights = {
  Thin: 100,
  UltraLight: 200,
  Light: 300,
  Regular: 400,
  Medium: 500,
  Semibold: 600,
  Bold: 700,
  Heavy: 800,
  Black: 900
};

@tonypee: for usage in StyleSheet i needed to change this to

export const fontWeight = {
    Thin: "100",
    UltraLight: "200",  
    Light: "300",
    Regular: "400",
    Medium: "500",
    Semibold: "600",
    Bold: "700",
    Heavy: "800",
    Black: "900"
};

Sorry but 100 to 400 is not working and 500 is working like 'bold' property. Did you notice this thing?

You can use https://www.npmjs.com/package/react-native-cross-platform-text to consolidate iOS and Android font weights into the same API

WOW thanks for this.
