After apply FastImage. It not working for me only show border with color red. Please help me thanks.
<FastImage
style={{height:100, width:100}}
source={{
uri: 'https://unsplash.it/400/400?image=1',
headers:{ Authorization: 'someAuthToken' },
priority: FastImage.priority.normal,
}}
resizeMode={FastImage.resizeMode.contain}
/>
You installed the library via npm install react-native-fast-image --save, probably run react-native link but you didn't add the libFastImage.a to your .plist configuration, which may be different from the one that the link command uses. That was my case.
After adding it to your dependecies, rebuild the project in XCode.

We have a winner! Thanks @tiberiumihai
What if you are using expo?
using expo 2, please help to make it compatible
@Unlighten @gogogous88 You can't use third party native modules with Expo. Vote it up: https://expo.canny.io/feature-requests/p/add-react-native-fast-image
