React Native Font Weight Cheatsheet iOS

RNfontWeights.js

{ fontWeight: '100' }, // Thin
{ fontWeight: '200' }, // Ultra Light
{ fontWeight: '300' }, // Light
{ fontWeight: '400' }, // Regular
{ fontWeight: '500' }, // Medium
{ fontWeight: '600' }, // Semibold
{ fontWeight: '700' }, // Bold
{ fontWeight: '800' }, // Heavy
{ fontWeight: '900' }, // Black

@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
