Summary:
When using XCTAssertEqualObjects to compare 2 swift arrays, it crashes.

Steps to Reproduce:
Use the following XCTestCase.

import XCTest

class Crash: XCTestCase {

    class Item : Equatable {
        var test: String

        init(_ test: String) {
            self.test = test;
        }
    }

    override func setUp() {
        super.setUp()
        // Put setup code here. This method is called before the invocation of each test method in the class.
    }
    
    override func tearDown() {
        // Put teardown code here. This method is called after the invocation of each test method in the class.
        super.tearDown()
    }

    func testExample() {
        var first = [Item("abc"), Item("def")]
        var second = [Item("abc"), Item("def")]

        XCTAssertEqualObjects(first, second)
    }

}

func == (a: Crash.Item, b: Crash.Item) -> Bool {
    return a.test == b.test
}


Expected Results:
Shouldn’t crash.


Actual Results:
Crashes in [SwiftObject doesNotRecognizeSelector:] (“iPhone 5s”, “iPad Air”, “Resizable iPhone”, “Resizable iPad”).
Or in [SwiftObject retain] (“iPhone 4s”, “iPhone5”, “iPad2”, “iPad Retina”).


Version:
Xcode Version 6.0 (6A254o), OS X 10.9.3 (13D65)

Notes:
* Implementing Equatable on the sub objects doesn’t seem to matter. It was added here for completion.
* This happens for all iOS simulator configurations coming with Xcode6b3. Didn’t manage to get it working on device.
* Haven’t tried on OSX.


Configuration:
Xcode + Simulator
