NativeModules is {} on iOS

Following https://reactnative.dev/docs/native-modules-ios, I'm unable to get NativeModules to contain anything. It's just an empty object (i.e. {}), but it should have the CalendarManager object and associated addEvent() method attached. This is true both for the simulator and my physical device. I was able to get an Android NativeModule working, so it appears to just be an iOS issue.

React Native version: 0.61.5
