A website's analytics have shown Apple devices running the unreleased iOS 13.
MacRumors have disclosed some very surprising site analytics today, showing some visitors using devices that are running iOS 13.0. They are suggesting that these are Apple IP addresses on the devices running the unreleased software.
The Apple-news website says that they first spotted iOS 13 devices in October, and then November and December. During late December, however, the visits slowed down, however this is due to the holiday break, most likely.
The devices seem to be iPhones running iOS 13, which is unreleased software. Apple usually announces major software updates at its annual WWDC conference in June, with a developer and public beta released days after.
It seems that Apple are working on iOS updates months in advance, and there seems to be a large team of people testing different devices, such as iPhones and iPads.
iOS 13 should bring some major design changes to the iPhone and iPad homescreen, along with larger features delayed from iOS 12. iPad should also get some massive updates, to open up the USB-C port on the new Pros, especially.
Now, 9to5Mac are suggesting they are seeing the same on their website, but since March 2018. This makes sense, as the features in iOS 13 were meant to come out last year but were delayed due to performance issues on the current version.
Detailed statistics from them show that hundreds of devices from Cupertino and Sunnyvale are accessing the website on iOS 13 devices and these places are where Apple is based.
