An iOS 13 screenshot in the beta, covertly named “HoldForRelease,” features the Calendar app with the date set to Tuesday the 10th.
The screenshot was originally found by iHelpBR, and the site points out that a similar screenshot was found last year ahead of the September 12 iPhone event with a September 12 date.
September 10 is a very likely date for the iPhone event based on the dates of past iPhone events, and we would be surprised were it not held on that date. Almost all iPhone events in recent history have been held during the second week of September, and generally on Tuesdays.
Last week’s Wednesday, September 12 event was an anomaly because September 11 fell on a Tuesday and Apple prefers Tuesday or Wednesday to Monday in order to give members of the media time to travel.
We’ve also heard the September 10 date bandied about from multiple sources that have contacted us. All three new iPhones are expected to debut at the event and see a release shortly after. Last year, the iPhone XS and XS Max were released in September ahead of the iPhone XR, which came in October.
With the iPhone event likely to be held on September 10, pre-orders for the new devices could take place on September 13 with a launch to follow on September 20. Apple often releases iOS updates two days ahead of when new iPhones become available, so iOS 13 could be released on September 18.
