Unable to delete an object in a realm database

I’m unable to delete an object in a realm database: I have following exception:

0x108196d6f:  movq   0x202112(%rip), %rcx      ; "exceptionWithName:reason:userInfo:"
0x108196d76:  leaq   0x1e6d0b(%rip), %rdx      ; @"RLMException"
0x108196d7d:  leaq   0x1e71c4(%rip), %rbx      ; @"Unable to delete an object not persisted in this Realm."

The record is in the database when I check with realm browser!!! Who had the same problem?

    If your goal is to delete all objects in the database, as the name of the deleteDatabase function would imply, all you need to do is call:

    let realm = RLMRealm.defaultRealm()

    Otherwise, if deleteUoMArray is an Array, RLMResults, or RLMArray of objects to delete, you can call realm.deleteObjects(deleteUoMArray).
