Test with TestFlight
TestFlight lets you install the real iOS binary built by Cadrant on physical devices — before public App Store release. This is the right way to validate native features (camera, push notifications, sensors, and more) that Expo Go cannot fully exercise.
Prerequisites
- A build uploaded from Cadrant — see Publish to App Store Connect.
- Access to App Store Connect for your Apple Developer account.
- The TestFlight app installed on the iOS devices you want to use.
Test your build with TestFlight
After Cadrant has uploaded the binary:
Open App Store Connect
Go to App Store Connect → My Apps → your app → TestFlight. The build uploaded by Cadrant should appear there (processing may take a few minutes).Complete export compliance if asked
Apple may ask you to answer a short compliance questionnaire before the build becomes available for testing.Invite testers
Add internal testers (App Store Connect users on your team) and/or external testers. External groups may require a brief Beta App Review the first time.Install on device
Testers open the invite in the TestFlight app, install the build, and exercise the app on a real iPhone — including native APIs.
What to validate on TestFlight
- Native APIs: camera, push notifications, sensors, file pickers, etc.
- Auth and backend flows against your Supabase project.
- Performance and navigation on a real device (not only the in-browser phone frame).
- Permissions prompts and edge cases (denied camera, offline, etc.).
