unarchiveObjectWithData:' is deprecated: first deprecated in iOS 12.0 - Use +unarchivedObjectOfClass:fromData:error: instead

i am using this library to integrate apple pay, after adding it it gives me error
"unarchiveObjectWithData:' is deprecated: first deprecated in iOS 12.0 - Use +unarchivedObjectOfClass:fromData:error: instead"
in this line
return [NSKeyedUnarchiver unarchiveObjectWithData:data];
Let me know how can i fix with this issue. i dont want to make changes manually in pod libraries.
need updated solution how can i upgrade this library because it installs braintree 4.. and this issue is resolved at brantree 5..
