Apple revealed its HomePod speaker, which rivals Amazon's Echo and Google's Home, earlier this year.
Because the speaker will have to work with Apple's new phone, it contains references to some of the upcoming features in its code.
Steve Troughton-Smith, a developer from County Limerick in Ireland, and Guilherme Rambo, a developer from Brazil, have been tweeting details about the iPhone 8 that they have discovered in the code.
Yesterday, they revealed that the iPhone 8 will have an edgeless display, and infrared camera, allowing users to unlock their phone just by looking at it.
And today, Mr Rambo uncovered a potential 'attention detection' feature in the code.
Mr Rambo tweeted: 'There's also a lot of new references to facial expression detection,' along with the section of the code he was referring to.
Facial references include 'mouthsmile', 'mouthfrown' and 'mouthpucker', which are likely to be linked to the rumoured facial recognition feature.
Mr Troughton-Smith meanwhile discovered a 'tap to wake' feature, that would allow users to double-tap their screen to wake their device.

He tweeted: 'It looks like the new iPhones might support 'tap to wake', much like Windows Phones/Lumias.'
The developers also confirmed the long-rumoured removal of the home button, in favour of a virtual one.
Mr Rambo tweeted: 'And the death of the home button is confirmed. RIP.'
While the developers did not find evidence of an ultrasound Touch ID, Mr Troughton-Smith said that a sensor under the screen was still a possibility.
He tweeted: 'I mentioned ultrasound, yes, but I searched for much, much more.
'There is no evidence whatsoever of any new
