**Feature summary** (what you would like to be able to do and where):
* on the Wikipedia iOS app, you can currently enter edit mode and attempt to publish an edit on a semi-protected page
* the warning that the edit cannot be saved (because the page is protected) happens only after you attempt to save your edit, which is super frustrating because you can put a bunch of time into an edit and then you're stuck because it can't be saved
* This is inconsistent with the mobile web and desktop behavior, where editing is prevented before you do the work of making changes to a protected page. On desktop Vector, the edit buttons are hidden completely and you only see View Source, which is also not very new editor friendly. The best experience is probably mweb, where you see the edit button with a lock icon and a toast error message is displayed (see screenshot). {F35338518}
**Benefits** (why should this be implemented?):
====Design proposition
If a page is semi-protected the editor should see an alert right after they tap on the edit pencil icon to edit the page.
- The alert will display a short message (the title of the semi-protected message) stating that the page is semi-protected and the editor will have two options to either tap on 'Ok' or to tap on 'Read more'.
- Tapping 'Ok' will dismiss the alert.
- Tapping on 'Read more' will open a full page modal with content that explains why/how the page is protected (if present originally).
- Tapping on 'Done' on the full page modal will dismiss the modal.
- If the editor is blocked from editing and they decide to edit a semi-protected page (they tap the edit pencil icon) the block message will appear (T275118). This block message will prevent the editor from editing the page. In this case they will not see the semi-protected alert.
