Compare Swift String and NSAttributedString

Question

How can I compare a NSAttributedString and a Swift String such that:

let string = "test string"
let attributedString = NSAttributedString(string: string)
let areStringsEqual = attributedString == string

will compile.

Answer 1

Two ways:

First

Change

attributedString == string

to

attributedString.string == string

Second

Add this to your code:

//for attributed.string == string
func ==(lhs: NSAttributedString, rhs: String) -> Bool {
    return lhs.string == rhs
}

//for string == attributed.string
func ==(lhs: String, rhs: NSAttributedString) -> Bool {
    return lhs = rhs.string
}
