Description
Describe your issue in detail. Include screenshots if needed. If this is a regression, let us know.
Prior to React Native 57+ Webview could load a base64 pdf on iOS since it was supported natively on UIWebview. After Expo recently upgraded to RN 57+ (Expo 31) our team hit this issue when using rn-pdf-reader-js since this library uses this functionality.
Usage
let data = "data:application/pdf;base64," + pdfbase64Data;
jsx:
<WebView
style={{ flex: 1}}
source={{ uri: data}}
/>
When loading the Webview we now get a promise rejection from resolveAssetSource().
NOTE: this image was taken from the expo forum post for rn-pdf-reader-js
NOTE: we haven't tried this with react-native-community/react-native-webview since it hasn't landed, but it seems that they have this working in their repository.
