Troubleshooting

For iOS you might run into a few issues such as follows:

Xcode: Undefined symbols for architecture x86_64: "JSObjectGetPrototype"

Refer to facebook/react-native#23183 for how to fix it

"TextCompositionLayer.swift" used twice IOS

Refer to lottie-react-native/lottie-react-native#523 for how to fix If doing the steps mentioned on lottie-react-native does not fix it, open Lottie.xcodeproj in your Xcode's project explorer under Libraries and search for TextCompositionLayer.swift. You might notice this file being included twice. Simply delete one of them from Xcode (reference only). It's basically including two copies of the same file. And that should resolve the problem for you.
