Opening vaults on iOS requires two taps: the second tap being the “Enter Vault” option. That extra tap is unnecessary.
Typical iOS behavior for elements like this would suggest putting the much less frequent rename/delete options in a context menu or secondary UI. For inspiration I would look to the Files app, where tapping on a folder opens it and a long-press brings up a context menu with options like Delete, Rename, etc. Since vaults are conceptually similar to folders this type of UI would seem to make sense.
