Xcode 12 support

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-native-qonversion@3.6.0 for the project I'm working on.

Here is the diff that solved my problem:

diff --git a/node_modules/react-native-qonversion/ios/.DS_Store b/node_modules/react-native-qonversion/ios/.DS_Store
new file mode 100644
index 0000000..96a379e
Binary files /dev/null and b/node_modules/react-native-qonversion/ios/.DS_Store differ
