Testing the text of an animated tag that appears and disappears

I am trying to check the appearance of a shortcut (toastLabel) that I have, which briefly revives when someone enters the wrong letter.

private func registerNewUser(email: String, password: String, confirmationPassword: String) {
    if password == confirmationPassword {
        firebaseData.createUser(email: email, password: password, completion: { (error, _ ) in
            if let error = error {
                self.showToast(in: self.view, with: error.localizedDescription)
            } else {
                self.showToast(in: self.view, with: "Registered succesfully")
                self.signInUser(email: email, password: password)
            }
        })
    } else {
        //raise password mismatch error
        print("password mismatch error")
    }
}

func showToast(in toastSuperView: UIView, with text: String) {
    let toastLabel = ToastLabel()
    toastLabel.text = text
    toastSuperView.addSubview(toastLabel)
    layoutToastLabel(toastLabel)
    animateToastLabel(toastLabel)
}

private func layoutToastLabel(_ toastLabel: ToastLabel) {
    toastLabel.centerYToSuperview()
    toastLabel.pinToSuperview(edges: [.left, .right])
}

private func animateToastLabel(_ toastLabel: ToastLabel) {
    UIView.animate(withDuration: 2.5, delay: 0, options: .curveEaseOut, animations: {
        toastLabel.alpha = 0.0
    }, completion: { _ in
        toastLabel.removeFromSuperview()
    })
}

I just want to check that the error text received back from firebase appears after the user enters an email that has already been accepted.

func testRegisteringWithUsedEmailDisplaysFirebaseError() {
    let email = registeredEmail
    let password = "password"

    welcomeScreenHelper.register(email: email,
                                 password: password,
                                 confirmationPassword: password,
                                 completion: {

        let firebaseErrorMessage = "The email address is already in use by another account."
        XCTAssert(self.app.staticTexts[firebaseErrorMessage].exists)
    })
}

func register(email: String, password: String, confirmationPassword: String, completion: (() -> Void)? = nil) {
    let emailTextField = app.textFields[AccesID.emailTextField]
    let passwordTextField = app.secureTextFields[AccesID.passwordTextField]
    let confirmPasswordTextField = app.secureTextFields[AccesID.confirmPasswordTextField]
    let registerButton = app.buttons[AccesID.registerButton]

    emailTextField.tap()
    emailTextField.typeText(email)
    passwordTextField.tap()
    passwordTextField.typeText(password)
    registerButton.tap()
    confirmPasswordTextField.tap()
    confirmPasswordTextField.typeText(confirmationPassword)
    registerButton.tap()

    completion?()
}

when I use other tools like wait and XCTWaiter, tests still fail, even though the text and label definitely appear. I have never had to do such a test, so I don’t know where I can be wrong, do I need to do something to check the animated view or something like that.
