Apple Seeds Second Developer Betas of iOS 18.1, iPadOS 18.1, and macOS Sequoia 15.1 With Apple Intelligence

Apple today provided developers with the second betas of iOS 18.1, iPadOS 18.1, and macOS Sequoia 15.1 to continue testing Apple Intelligence features. The second betas come two weeks after Apple seeded the first iOS 18.1, iPadOS 18.1, and macOS Sequoia 15.1 betas.

Apple Intelligence Feature 2
A device capable of supporting ‌Apple Intelligence‌ is required to download the updates, which includes the iPhone 15 Pro and Pro Max, Apple silicon iPads, and Apple silicon Macs. The updates can be downloaded from the Settings app on a compatible device, with developers able to choose between the standard iOS 18/iPadOS 18/macOS Sequoia 15 betas or the .1 betas with ‌Apple Intelligence‌ functionality.

‌Apple Intelligence‌ includes Writing Tools that are available wherever text can be selected and edited, and it can be used for spell checking, fixing grammar, rewriting with a new tone, and summarizing text.

Siri has a new design with a subtle glow around the display, and there is a Type to ‌Siri‌ feature so you don't have to speak to ‌Siri‌. ‌Siri‌ can follow along if you stumble over your words, and can maintain context between requests. Safari can summarize articles, and there's a new Reduce Interruptions Focus Mode.

Smart replies are available in Messages and Mail, plus the Mail app surfaces time sensitive messages and puts them at the top of your inbox. Photos has a Memory Movie feature for creating slideshows based on text descriptions, and you can record, transcribe, and summarize phone calls. Transcription and summarization are also available for any audio recording.

More on all of the features that are available in the betas right now can be found in our Apple Intelligence guide. Image Playground, Genmoji, and other new ‌Siri‌ features have not yet been implemented.

Apple has split ‌Apple Intelligence‌ into a separate set of betas because these features will not be available in the initial launch versions of iOS 18, iPadOS 18, and macOS Sequoia. ‌Apple Intelligence‌ will be available to the public later in the fall after a developer testing period.

I'm probably in the minority but I have little to no interest in AI and this makes me feel like I've now become my parents/grandparents generation ??‍♂️

Something about AI just intimidates me ?‍♂️ I am in no rush to go from iOS 18.0 to 18.1
If maybe there was just an option to turn off AI……………

18.1 is just a Siri with rainbow colours.
Yes. As far a I understand, you're right.

The changes in 18.1 are :

* The design (rainbow colors)
* You can stutter and it'll still understand
* You can change your requests in the middle of a sentence and it'll understand the latest request

The real Siri upgrade will be after 18.1.

[HEADING=2]Apple Intelligence Localization (iOS 18.1)[/HEADING]
Apple Intelligence includes new localized versions of English in the second 18.1 beta. Options include Canada, Ireland, New Zealand, South Africa, India, and Singapore, which are in addition to the previous U.S., UK, and Australia localization options.
Can someone explain this new feature in beta 2?

If I switch Siri to UK English, it prompts me to use US English. I read the release note, which states that it will now work with UK English.

Additionally, I’d like to revert my phone region to UK because my signal on EE is poor and frequently switches to “no service” before returning to 5G. I haven’t had enough time with beta 2 to determine if this issue has been resolved yet.
