The following function:

    func testCorrectAnswer() {
        let N = 8
        let weight = 4
        let oddWeight = 5
        
        for var n = 0; n < N; n++ {
            var balls: [Ball] = []
            for i in 0..<N {
                balls.append(Ball(weight: weight, index: i))
            }
            balls[n] = Ball(weight: oddWeight, index: n)
            
            let found = findOddBallOutCorrectAnswer(balls)
            let index = found?.index ?? -1
            XCTAssertEqual(index, n)
        }
    }

Causes the compiler to trap under release mode when building for test.

Specifically, it is the “XCTAssertEqual(index, n)” line that is causing the issue. 

I’ve attached the project.
