Migrating from v1 to v2
Version 2 of the React Native tracker underwent a large rewrite of the internal code, both on the side of the React Native project as well as in the underlying iOS and Android trackers (which have been upgraded to version 5). However, the public APIs and tracker behavior have remained largely unchanged except for a few things discussed on this page.
Installation on iOS
In addition to adding the tracker as a dependency in your package.json, you will also need to add the FMDB dependency to you ios/Podfile (unless using Expo Go) with modular_headers enabled. Add this line to the end of the file:
pod 'FMDB', :modular_headers => true
Supported iOS platforms
The supported platforms have changed on iOS:
- Minimum iOS deployment target changed from 9.0 to 11.0.
- On macOS, from 10.10 to 10.13.
- On tvOS, from 9.0 to 12.0.
- On watchOS, from 2.0 to 6.0.
IDFA tracking on iOS
The approach to track the IDFA identifier has changed in the underlying iOS tracker version 5. This means that you will need to take a different approach to set it up. The new approach is described in the documentation here.
Automatic screen view tracking default
The automatic screen view tracking configuration (set by TrackerConfiguration.screenViewAutotracking) has been changed to disabled by default. In case you rely on the default value and want to keep using the feature, please set it manually when creating a new tracker.
The feature was disabled because it does not track screen views for React Native screens but for UIKit and Android Activity screens which is not what users expected in most cases.
