I have done lightweight migration and overwrite the build and verified that it was working as expected. After the application is released in the Appstore.
We are getting the following error saying the migration failed. We captured this through Fabrics(Crash reporting SDK).
Crash observed in iOS 10.2.1 and iOS 10.3.1 and devices iPhone6 and 6s.
My question is, If migration failure is the problem then all the user should have affected by this crash. So is there any other reasons like database corruption only for those 2 users.
