기존 NSSQLiteStore를 SMStore.Type (Seam3)로 적절하게 마이그레이션하고 이상한 문제가 발생하는 경우 계속 시도하고 있습니다. 왜 그런지 이해할 수 없습니다. 나는 the same for Paul on github을 제기했지만 아마도 누군가가 내 코드에서 그 원인을 발견하고 도울 수있을 것이며 폴은 바쁘다.NSSQLite를 Seam3 저장소 유형으로 마이그레이션 할 때 EXC_BAD_ACCESS가 실패합니다.
무엇이 있습니까 : 기본 폴더에 NSSQLiteStore가있는 iOS 10 이상에서 실행되는 앱입니다. 테스트
단계 :
(있는 경우) 새로운 저장소를 제거하고 새로운 경로에있는 파일 지원의 : 파일 : /// 사용자/DJ-글 록/라이브러리/개발자/CoreSimulator/장치
실행 응용 프로그램을 /3708F142-3BD0-4C70-8515-217B7785D285/data/Containers/Data/Application/29B60BBC-0D17-4D6C-8107-0135C45B20BA/Documents/CafeManagerSeam3.sqlite. 새로운 상점이 있는지 앱에서 확인해야합니다. 그렇지 않은 경우 - 기본 마이그레이션에서 마이그레이션을 수행하십시오.
응용 프로그램은 저장소를 마이그레이션하려고 시도하며 EXC_BAD_ACCESS로 실패합니다. 그러나 같은 시간에 새 저장소가 새로운 경로에 나타 났으며 다시 한 번 응용 프로그램을 실행하면 눈에 띄는 문제가없는 새 저장소가 사용됩니다.

What am I doing wrong? Is it my misunderstanding of CoreData stack or something else?
