Correction for a Warning

[geogerar]

Hello,
First of all I would like to thank you for your nice and helpful tool.
I have just a request, if you have time ofcourse.
Can you correct the following warning |:

"Hashable.hashValue' is deprecated as a protocol requirement;
conform type 'Item' to 'Hashable' by implementing 'hash(into:)' instead"

I thank you in advance for your help.
