Apple has released the latest iOS 13 developer beta which is the seventh iteration of the beta version. It means people started digging into the source code to find any new references to get an idea about Apple's future plans. As it turns out, iHelp BR folks discovered something that suggests a possible iPhone 11 launch event date.
The new iOS 13 beta includes a couple of new reference images for iOS home screen with Calendar app icon set to date "10" and Tuesday. If you will refer to any 2019 calendar, you will see that September 10th is also falling on Tuesday. It means there is a good chance that Apple is set to announce the 2019 iPhone lineup at an event scheduled for September 10th.
This is similar to what happened last year when an image was found with the Calendar app showing September 12th date. It is the same date when Apple launched iPhone XS, iPhone XS Max, and iPhone XR. It means it would not be surprising if the same thing happens this time around as well.
Moreover, 9to5Mac has shared an interesting observation that Apple prefers launching new iPhones on the second Tuesday or Wednesday of September. This has been true for launch events held in the last four years and since September 10th is the second Tuesday, it is another reason to believe that it could actually be the release date.
Apple is rumored to launch three iPhone models this year which will be succeeding respective current-gen models. A recent leak claimed that these will be released as the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max. The first one is expected to sport an IPS LCD display variant and the other two with OLED display panels.
