Implement to get fetch the data from Contacts and implement the search in firstName,LastName and phone numbers

-
Solution:

 You cannot be able to search the firstName,LastName and phone number in contacts List because it is a dictionary with multitypes.So predicate will not be possible.So you can get the contact and save it in a dictionary with firstName and LastName as two keys and phone number as one key with concatenating the all phonenumbers in a single contact as a string and implement the search in the dictionary will works good.
