.synchronizable(true) item doesn't return in Keychain.allItems(.genericPassword)

[Gurbo]

If I save items with .synchronizable(false) and then get all items with Keychain.allItems(.genericPassword) - the returned results are valid.

Next I save an item with .synchronizable(true) and then get all items with Keychain.allItems(.genericPassword) - it returns only items, which were saved with .synchronizable(false). (but this item appear in iCloud Keychain as well).

Any ideas? @kishikawakatsumi
