Swift Parse Searchbar isnt working - swift

Question

I have a parse class of country names, and have a swift tableview controller that pulls the list of countries from Parse and allows you to search for country name. For example:
Canada
China
Iraq
etc
If I search for "Canada" nothing comes up, but if I search "anada" I get results. For some reason it is ignoring the first character, any idea why this is happening?

Just realized the query.wherekey function is not case sensitive, fixed the problem
