Apple announced WWDC25 earlier this week, to the point on June 9. This means that we are on our doors to see all Apple software upgrades, including iOS 19, iPados 19, MacOS 16, Visionos 3, TVOS 19, Watchos 12, and perhaps even more.
IOS 19 should receive a massive overhaul this year, bringing a new layer of paint to the operating system. However, here, we will focus on the second cycle of Apple’s APP functionalities to come on iPhone.
Trio of Siri’s delayed features from iOS 18.4
First of all, iOS 19 will probably present the three major Siri upgrades that the company announced at WWDC24. These features were supposed to go out within the framework of iOS 18.4 this spring, but the company announced that it would need more time to work there.
These three features are as follows: personal context, awareness of the screen and taking measures in the applications.
This trio of features would have allowed Siri to better understand who you are, see what you are doing on your phone while you are talking to him and taking measures on your behalf. It would have made Siri a global digital assistant that many people dreamed of.
Apple did not provide a lot of specific calendar when it has delayed these Siri features already announced. He said they would deploy “in the coming year”, it is therefore not clear whether or not it will be part of iOS 19 or iOS 19.1 later this fall, or if it will take place in a winter or spring outing. Only time will tell us.
LLM SIRI
Bloomberg Mark Gurman Reported last year That Apple worked on a new Backend Siri for iOS 19 – which he called “LLM Siri”. This had to be accompanied by a new interface of conversational Siri, although this part was delayed until iOS 20.
However, the new Backend LLM Siri is still launched as part of iOS 19 and will be fundamental to allow the three above -mentioned features of three iOS 18.4 features. De Gurman Power on Newsletter::
In order to bring the Apple door out as part of iOS 18, the company did not have time to merge the two systems together. This means that the software does not work as well as possible.
For iOS 19, Apple’s plan is to merge the two systems together and deploy a new SIRI architecture. I expect this to be introduced from the global conference of Apple developers in June of this year – with a launch of spring 2026 as part of iOS 19.4. The new system, nicknamed “LLM Siri” internally, also had to introduce a more conversational approach in the same version. But it also takes place behind and will not be revealed in June.
With this new backend “LLM Siri”, Apple will finally obtain a unified SIRI system, which will be hopeful, easier to build in the future. For the context, Siri currently draws two different backends when creating requests: a heritage for simple tasks and a modern for more complex requests.
The launch of LLM Siri will not have an immediate advantage for the end user in terms of new features, at least up to iOS 20 when the conversational aspect of it starts.
Extension between applications
Apple would also have widened some of its Apple Intelligence features already published to more applications. This probably means that we will see image playground, Genmoji and Apple’s summary features in more places, by Bloomberg::
The bad news is that Apple is unlikely to reveal the new influence features on this upcoming WWDC. Instead, it will probably establish plans to provide current capacities to more applications.
This also means that Apple will probably not introduce any fundamentally new measure of Apple Intelligence in iOS 19, beyond what it has already announced.
