[cbaker6]

New Pull Request Checklist

• I am not disclosing a vulnerability.
• I am creating this PR in reference to an issue.

Issue Description

• Options are missing from matchesText query constraint along with ability to see score. Completes missing server features from Full Text Search Support parse-server#3904
• The withCount query constraint is missing, discussed in Add count flag to Parse.Query.find Parse-SDK-JS#865

Related issue: #n/a

Approach

Add the capabilities mentioned above similar to the JS SDK implementations. Examples of how the new features can be used are in the modified Swift Playground files.

A breaking change is introduced because score should be a reserved property that can' be modified by developers. The compiler with assist developers in addressing the change by recommending var score: Double? be added to all ParseObject's.

Changes you will need to make:

• Add var score: Double? to all ParseObject's

TODOs before merging

• Add tests
• Add entry to changelog
• Add changes to documentation (guides, repository pages, in-code descriptions)
