RNPermissions is null only on iPhone 8 simulator device

[csilzen]

Bug

Works fine on iPhone 11 and iPhone 11 Pro Max simulator devices (both iOS 13.3). However, when switching to iPhone 8 running iOS 13.3, keep seeing this error.

Info.plist includes

<key>NSCalendarsUsageDescription</key>
<string>Calendar Access Notice: selected event will be added to your device calendar</string>

Podfile includes

permissions_path = '../node_modules/react-native-permissions/ios'
 # (I have also tried with this uncommented)
 # pod 'RNPermissions', :path => "../node_modules/react-native-permissions/RNPermissions.podspec"
pod 'Permission-Calendars', :path => "#{permissions_path}/Calendars.podspec"

I have done xcode clean, rm -rf node_modules, pod cache clean, and reinstalled/relinked everything (npm i, pod install, react-native link). Not sure what to do anymore.

2. Metro Bundler reloads as excpected. Dependency graph runs as expected. No errors shown on Metro Bundler.
3. Errors shown on simulator (photo above).
4. I have done xcode clean, rm -rf node_modules, pod cache clean, and reinstalled/relinked everything (npm i, pod install, react-native link). Not sure what to do anymore.

Describe what you expected to happen:

Use react-native-clean-project?

@csilzen Like @mikehardy said, try using react-native-clean-project (to delete Xcode stale data, like the DerivedData folder): npx react-native-clean-project --remove-iOS-build --remove-iOS-pods

it's also accessible if you go in the Xcode menu > Preferences > Locations > and you click on the little arrow to open the folder, delete its content.

Thanks for you responses! For whatever reason, switching to a different version of node and then switching back helped. Next time I'll try running react-native-clean-project
