13’s Apple Developer Newsletter #255 🉐13+ Black Friday Offer & iOS On-Device AI Series Preview
A19 Pro faster than M3 Max? Previewing December's on-device AI article series and inviting new friends to join 13+ through the rare Black Friday offer.
I just returned from a brief vacation. This trip accumulated some inspiration and stimulation, leading me to decide to write a series of articles on running local AI on iPhones starting in December, and to announce a limited-time offer for 13+.
Recently, I’ve been doing a lot of iOS development teaching and have accumulated some experience exploring local AI applications. For instance, testing on iPhone 17 Pro Max revealed: Foundation Models generate tokens about 25% faster on A19 Pro than on MacBook M3 Max. I’ll explain the reasons in upcoming articles, but you can see that Apple’s hardware performance improvements have huge advantages for local AI inference.
Beyond hardware performance, running local AI on iPhones has many interesting aspects and prospects. I think many iOS developers don’t want to “do AI for AI’s sake,” or want to add it but don’t know how to start. In reality, some situations for developing AI applications simply didn’t exist before Foundation Models or A19 Pro were released. Starting today, you’re on the same starting line as developers worldwide—no need to worry about falling behind. Even I’m researching and sharing as I go!
I plan to write multiple articles covering:
Observed facts, testing methods and results, Apple’s advantages in local AI, issues with development experience and possible developments, and presenting a major insight: iOS developers are the group of people in the world with the best opportunity to create excellent local AI application user experiences, bar none.
If you’re an iOS developer, this is a series of articles you won’t want to miss. If you’re already interested but haven’t joined as a member yet, take advantage of the Black Friday offer that only happens once a year for the 13+ column.
Subscribe to 13+ on Patreon, enter discount code LOCALAI, and enjoy 13% off your first month. Available only until Cyber Monday 2025/12/01 23:59.
Honestly, offering discounts isn’t my style. But this series will contain observations + experience sharing + operational instructions + insights that you can’t read elsewhere, and it will be content that best demonstrates the value of the 13+ column. I want to give friends who’ve been on the fence a good reason to join.
If you’re unfamiliar with 13+, check out the website directory to see what article topics we’ve covered. I particularly recommend the Special Feature: Investigating the Impact of iPhone USB Speed on Development Experience, which has extensive testing, hands-on operations, and insights—you could say it’s the predecessor to the local AI series. Additionally, from mid-August until now, I’ve been challenging myself to publish new articles every workday, so every Monday through Friday morning you can read a new piece—it’s great mental stimulation and learning for readers.
Tomorrow will be the last article of November, which as usual will be a monthly review sharing my favorite articles. Starting next Monday, we’ll launch the iOS local AI article series.
Finally, please share this announcement with iOS developers around you, or friends interested in AI application development. I believe it will help many people!
