Re-initialize a lazy initialized variable in Swift

Question

I have a variable that initialized as:

lazy var aClient:Clinet = {
    var _aClient = Clinet(ClinetSession.shared())
    _aClient.delegate = self
    return

There are some good answers here.
Resetting a lazy var is indeed, desirable in a lot of cases.

I think, you can also define a closure to create client and reset lazy var with this closure. Something like this:

class ClientSession {
    class func shared() -> ClientSession {
        return ClientSession()
    }
}

class Client {
    let session:ClientSession
    init(_ session:ClientSession) {
        self.session = session
    }
}

class Test {
    private let createClient = {()->(Client) in
        var _aClient = Client(ClientSession.shared())
        print("creating client")
        return _aClient
    }

    lazy var aClient:Client = createClient()
    func resetClient() {
        self.aClient = createClient()
    }
}

let test = Test()
test.aClient // creating client
test.aClient

// reset client
test.resetClient() // creating client
test.aClient
