Задача

class TestClass {
    var block1: (() -> Void)?
    var block2: (() -> Void)?

    func test() {
        block1 = { [weak self] in
            self?.block2 = {
                print(self)
            }
            self?.block2?()
        }
        block1?()
    }

    deinit { print("deinit") }
}

var object: TestClass? = TestClass()
object?.test()
object = nil
