Builds on Xcode 12 and above fail due to this library.  The issues seems to be related to [this](https://github.com/facebook/react-native/issues/29633). To fix it we would need to make changes as mentioned [here](https://github.com/facebook/react-native/issues/29633#issuecomment-826620412) to the podspec, ```diff - s.dependency 'React' + s.dependency 'React-Core' ``` https://github.com/wonday/react-native-pdf/pull/509/files#diff-5faac750e13626b2dc95e4621e009a7130bc2919068cd64ae68beb55e0899344L17-R17
