推荐答案

您首先必须获取记录，然后将其更改并保存回去.如果您遇到相同的错误，那么记录将被其他人更改.您可以从错误中获取更改的记录，也可以再次获取它.然后再次应用更改并将其保存到CloudKit

You first have to fetch the record, then change it and save it back. If you get the same error, then the record is changed by someone else. You can get the changed record from the error or you could just fetch it again. Then again apply the changes and save it to CloudKit
