The secrets of the next iPhone's are always kept under close guard. The occasional leak is offered, as a little tempter, but most of the features are kept under wraps until the big launch.
However, within the development of their HomePod, the code has given some big hints about the future of the iPhone.
The HomePod is to launch to rival Amazon's Echo, and Google's Home. But, of course, the speaker will work with the latest iPhone.
Two developers, Steve Troughton-Smith of County Limerick in Ireland, and Guilherme Rambo, from Brazil, have been tweeting about the findings they've discovered in the code of the HomePod.
One of the most expected things in the latest upgrade of the iPhone has been confirmed in doing so. The home button will no longer exist.
They've revealed that the iPhone 8 will have an edgeless display and infrared camera - meaning users will be able to unlock their phone just by looking at it.
Mr Rambo tweeted: "There's also a lot of new references to facial expression detection," along with a section of code he was referring to.
These include: 'mouthsmile', 'mouthfrown' and 'mouthpucker' which are likely to linked to facial recognition.
Troughton-Smith discovered a 'tap to wake' feature in which a double-tap of the screen will see the phone wake up. It's a feature already common on Windows phones.
In a separate tweet, he mentioned how the iPhone will join the Samsung Galaxy 8 in its infrared face unlock system.
The advantage of this is that infrared can also measure other parts of your body, including your heart rate.
Rumours have been consistently swirling about how the new iPhone may look. Concept pictures, released by iDrop News made the eight edition looks pretty sick.
Other leaks seem to suggest that being tethered to the cord of your charging cable may soon be a thing of the past.
Wireless charging could be made available for the iPhone 8 with pictures released of its potential charging coil - and it will be made as a standard feature, much like the wireless headphones were.
The latest iPhone is expected to be released in October.
