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. George Gerardis
