String not convertible to [AnyObject]

问题:

I have a string declared as var searchString = ""

I am trying to do parse query as shown below: query?.whereKey("username", containedIn: searchString)

What is the issue?

This is in Xcode 6.3 updated and also Swift 1.2.

The function expects an array of AnyObjects, you supply a String. Simply wrap the string in an array...

query?.whereKey("username", containedIn: [searchString])
