Unit test can't find class to test

I've got a stock standard class call GeoRssParserDelegate which needs to be tested.

In my swift unit test I've got this:

func testParser()
{
    var bundle = NSBundle(forClass:GeoRssParserTest.classForKeyedArchiver())
    var path = bundle.pathForResource("test", ofType: "xml")
    let data = NSData.dataWithContentsOfFile(path, options: NSDataReadingOptions.DataReadingMapped, error: nil)
    let xmlParser = NSXMLParser(data:data)
    let delegate = GeoRssParserDelegate() <-- Compiler fails here
    var bStatus = xmlParser.parse()
    XCTAssertTrue(bStatus, "Parse failed", file: __FILE__, line: __LINE__)        
}

The compiler fails on the line highlighted above. The compiler error is Use of unresolved idenitifier GeorRssParserDelegate

This class does exist and builds with the product itself. Is anything special required?

For me the reference or value type that I wanted to test is not marked as public. That's why I've just used as copy-paste for the associated type.

Solution for Xcode 8 and UP which works for me: 

@testable import Product_Module_Name

note: not the target name but product's name.

Regarding answers above: making without @testable will require to make classes and methods public which changes the design of the app architecture. if you don't want to change it better to use this solution so you won't need to make changes to class being public or no.

Many thanks to this answer

@testable import MyApp

IMPORTANT! Note: MyApp must be the product module name in your project (Settings -> Target -> Build Setting -> Product Module Name)

Do the following 3 steps --> 1. Write @testable import Your_Project_name 2. Then save (CTRL+S) 3. Then build (CTRL+B)

You have to import your application's module into your unit test. This is usually your app name. For example, if your app name is GeoRssParser the import statement would be:

import GeoRssParser

If you're using brand new XCode 7 (as of Jul 21, 2015), simply write: @testable import GeoRssParserDelegate

Just add the class you are testing to Target -> Build Phases -> Compile Sources

It's how I fixed my problem.

If the class you're testing is compiled into another target (such as your application, as opposed to the test bundle), make sure that the class or struct you're trying to use is marked public -- the default access visibility doesn't allow for cross-target testing.
