Notes

• This PR covers logic to show alert when clicking on edit introduction. Alert has been shown only once, when clicked "Yes".
• This is my first PR to WIKI. Need suggestions to confirm the localize string implementation is correct or not. also ticket only mentions to have something so the user knows the order is different. based on that I have used alert to show only once.

Test Steps

1. Open any article.
2. Click on pencil in right.
3. Click on "Edit introduction"
4. the new alert will appear.
5. Click "Yes" to proceed, click "cancel" and the repeat the flow again to show Alert.
6. If clicked "Yes" and want to see Alert again, uninstall app and re-install again.

Hi @rajparad! Apologies for the review delay on this one. This all looks good from a code perspective - nice work! I will ask our designers to review further in case they have any additional behavior or copy tweaks before merging. Thanks!

Hi @rajparad - apologies for the delay. I think we can get pretty close to option #1. You'll want to put in in the correct places in PageEditorViewController. We have a toast component that can be triggered like this:

WMFAlertManager.sharedInstance.showWarningAlert("Text here", sticky: false, dismissPreviousAlerts: true)

The design won't match up exactly, but that is okay.

You can trigger within loadContent once all the content is loaded in this method, if no issues have cropped up (i.e. no blocked error, no edit notice is displayed, etc.).

If an edit notice modal is automatically presented, you also want to try triggering it after that edit notice modal is dismissed. Usually the featured article of the day has an edit notice, if you want to test that and see how it behaves.

Hope this helps. Let us know if you have any other questions, thanks!

Hello @tonisevener, Thanks for the feedback. I have updated the code to show warning. For now it's only show one time for a user.

Only thing I am curious is it's now only work with English. I am not how to work with localization in project. Let me know if it's fine or not.
