Getting unknown "dangling reference" warning

[biblicabeebli]

Object 0x10e70c000 of class _ContiguousArrayStorage deallocated with non-zero retain count 3. This object's deinit, or something called from it, may have created a strong reference to self which outlived deinit, resulting in a dangling reference.

The encryption code does show a warning about creating a dangling reference, will need to take a look at that I guess.

This occurred while inside the loop trying to upload many many files on a test device.
