Safari Browser: Switch to frame is not working - selenium

Question

I am trying to run few test on Mobile Emulators (Safari Browser) and stuck at a problem. Where after switching to an Iframe I am not able to do any action.
There is already a closed issue for that, however I didn't find any solution after going though this thread.

Code which is causing issue
public PaymentPage fillCreditCardInformation(String cardNumber, String expiryDate, String cvv, String postal ){
switchToPaymentFrame();
WebElement cardNumberEditbox = driver.findElement(By.name("cardnumber"));
}
private void switchToPaymentFrame() {
WebElement frame = driver.findElement(By.name("__privateStripeFrame3"));
driver.switchTo().frame(frame);
}

Answer 1

Can you try this:
Change:
private void switchToPaymentFrame() {
WebElement frame = driver.findElement(By.name("__privateStripeFrame3"));
driver.switchTo().frame(frame);
}
To:
private void switchToPaymentFrame() {
WebDriverWait wait1 = new WebDriverWait(driver, 10);
wait1.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.name("__privateStripeFrame3")));
}

Answer 2

Seems to me like a known issue.
Simply doesn't work.
