Hey @ytyubox! Thanks for reaching out!

Yes, aroundEach should be able to do this for you, I'd write that test like so:

var sut: Subject?
aroundEach { example in
    autoreleasepool {
        sut = makeSut(...)
        example()
    }
    expect(sut).to(beNil())
}

Which should do what you want, but I didn't verify that code myself.

You can also still use the XCTest-based methodology with addTearDownBlock inside of a test, like so:

it("deallocates correctly") {
    let sut = makeSUT(...)
    addTearDownBlock { [weak sut] in expect(sut).to(beNil()) }
    return sut
}

Hope that helps!
