I'm Gary Bennett. I've built Apple apps for brands like Life Time and Choice Hotels, co-written Apress's beginner books on Objective-C and Swift, and now help teams add AI to their products, including private models that run on hardware they control.
Send a short note and I'll set up a free 30-minute call.

Bring an app idea, an app that needs rescuing, or a pile of data you want to ask questions of.
An iPhone, iPad or Mac app that passes review and that people keep using. New builds, or taking over an app another team left behind.
Good fit: a product team or a business with an app idea or an aging app.
Assistants and features that answer from your own data, with read-only access, budgets and audit logs designed in from day one.
Good fit: teams with useful data that's hard to get answers from.
A local model server sized for your data and your budget, with secure access for your apps. No per-token bill, and nothing leaves the building.
Good fit: healthcare, legal, finance and anyone with data that can't go to the cloud.
Practical sessions built around your team's real tools and data, from someone who has taught technology courses since 2009.
Good fit: teams that have AI licenses but aren't getting much from them.
The best AI setup for most businesses isn't one model. It's a choice made per question: the strongest cloud model when it matters, your own hardware when the data is sensitive or the volume is high.
Patient records, contracts and logs never leave your network.
Pay once for hardware instead of a bill that grows with every question.
Open-weight models and standard APIs, so you can switch models as better ones arrive.
TrueAccess · Swift · CoreBluetooth
Vendors visiting hospitals need to check in at the right building, even when several hospitals share one address.
Geofencing with polygon detection for each building, and a wearable Bluetooth LED badge that shows access status at a glance.
An app that now ships under partner brands, with a logging pipeline that turns field reports into fixes.
Claude · local LLM · Postgres
Answering a support question meant an engineer digging through app logs and the source code.
A chat assistant over the logs and a code mirror, with a read-only database role, one query at a time, budgets and an audit log.
The support team asks in plain English. Each question can run on Claude or on the private model.
SwiftUI · Vision · MLX
Tasks, meeting notes and receipts were spread across too many apps.
One app for iPhone, Mac and Vision Pro that reads receipts with on-device OCR and pulls tasks out of meetings with a local model.
Meeting transcripts never leave the Mac, and nothing gets lost between apps.
A free 30-minute call about what you need and whether I'm the right fit.
A written plan and a working prototype you can tap through before the full build.
Weekly builds on TestFlight or a staging site, then release.
Monitoring, fixes and documentation so your team can own it.
Yes. Small models run on the iPhone itself with Apple's on-device frameworks, and larger ones run on a server in your office. I set up the private model, connect your apps to it, and route only the questions you choose to a cloud model like Claude.
It depends on the model and how many people use it. A Mac Studio with 128 GB of memory runs a 120-billion-parameter model comfortably for a small team, and smaller models run on far less. I'll size it to your use before you buy anything.
Yes. Much of my work is improving existing Swift apps: finding the bugs field reports point to, modernizing old code and getting releases moving again.
Yes. I've worked with national brands and with small businesses. The process scales down: a short plan, a prototype and regular builds.
Yes. Workshops can stand alone or come with a project, so your team keeps building after I hand it off.
Send me a short note on LinkedIn about what you're trying to do. We'll set up a free 30-minute call, and you'll come away knowing whether it's a fit, roughly what it takes, and what to do first.
