Testflight iOS crash data

Hello,

Does anyone have any insights on retrieving crash data from Testflight, from the beta testers devices?

I found this tutorial: Using the Beta Testing Adobe AIR native extension to test iOS games and apps | Adobe Developer Connection

It uses a Beta Testing Adobe AIR native extension.

Is this still the current best practice for testing on iOS? Or is there another method using xcode?

Thanks for reading,
