Navigate through next button in textFields iOS swift

-
Problem:

 I want to navigate to next field that wants to be focusable when i click next button.If i click the end textfield then keyboard wants to be hidden.
Solution:

 In textfield delegate method do the following.

Objective c:


    -(BOOL)textFieldShouldReturn:(UITextField*)textField
    {
    NSInteger nextTF = textField.tag + 1;
    UIResponder* nextResponder = [textField.superview viewWithTag:nextTF];
    if (nextResponder) {
    [nextResponder becomeFirstResponder];
    } else {
    [textField resignFirstResponder];
    }
    return NO;
    
    }



Swift:


    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        let myTextField = textField.tag + 1
        let nextResponder = textField.superview?.viewWithTag(myTextField) as UIResponder!
        
        if nextResponder != nil {
            nextResponder?.becomeFirstResponder()
        } else {
            textField.resignFirstResponder()
        }
        
        return false
    }

Solution: If you saved the entire path like file://....png then it is not possible to get the image because document directory path will be dynamic.So better you can save the imagename in your coredata after that below code to get the image.
