The world's largest IRL gathering of Apple developers

June 9-12

alongside Apple's WWDC in Cupertino, CA

Welcome

Welcome home, developers!

Let’s gather on an exhilarating journey where collaboration sparks creativity and every moment holds the promise of magic.

One More Thing is the community-run neighbor conference to WWDC. We’ll be gathering for talks, for workshops, for WWDC-labs-inspired experiences enabled by community experts, and to meet fellow developers in a shared space.

One More Thing is born out of gratitude and passion for our wonderful community and is inspired in large part by the conferences we know and love from 2019 and earlier.

FAQ

We are headquartered at the Residence Inn on Main Street in Cupertino, CA.

Main Street has lots of hip little shops, cafés, and restaurants, plus you can walk to the Apple Visitor Center to explore swag.

Tons! Classics include James Dempsey and the Breakpoints, and Daring Fireball. Stay tuned in our newsletter or the swift community forums for updates.

Are you planning a morning, daytime, evening, or weekend event? Please let us know and we might send you special invitations. And remember, we’re accepting special event proposals.

We’re at the heart of Apple’s greater campus, in walking distance of the thousands of attendees flown in for WWDC, and surrounded by thousands of Apple employees in the area and Infinite Loop.

Part of what has made WWDC-week conferences such a magical experience in our past has been the proximity to the thousands of developers that Apple flies in from around the world. Main Street in Cupertino has been a popular area for WWDC afterparties in recent years and the mingling between these groups and conferences will happen naturally.

Commonly called that “one fun place in Cupertino”, Main Street has many places to enjoy gatherings and hosted events that bring us together.

Nearby hotels include AC Hotel, Hilton Garden Inn, Courtyard by Marriott, Hyatt House. Airbnb is also a popular choice.

We are headquartered at Residence Inn, so that’s a wonderful choice, but please note those rooms are at a very high premium and will be gone early and quickly. Currently SOLD OUT, though rooms may sometimes pop up as available again.

Many attendees will be coordinating with others around housing. One place to request or offer housing is the Swift Community Forums. Another is with hashtags #OMT25, #WWDC25, and #OneMoreHost on your favorite platform(s).

Please encourage your peers in Silicon Valley to offer to Host A Coder this week.

guaranteed seats In the Main Room, You have guaranteed entry in the main speaker room.

best seats In the Main Room, the best seats are reserved for your tear. In our Tents, you benefit from reserved seats and/or preferred entry.

seat upgrade for weekend workshops, you get the best seats available within your purchased workshop tier

A significant percentage of attendees fly in to join us here and we welcome you. Last year, you joined us from 37 countries. 

To welcome you extra warmly, wherever limited tickets (or limited free RSVP) become available, we will special-release a few additional tickets for those who fly here.

Why FREE? We value the magic that happens when we gather in greater numbers.

Why Paid? To reach our funding goals so we can exist.

Refund and cancellation policy: You can cancel your ticket and refund within 14 days of purchase. The refund will be provided in the form of a coupon that you can use for another event by One More Thing. Certain tickets may be exchanged for tickets from us of equal or higher price. A per ticket exchange fee may apply.

PRIVACY-FORWARD Notice regarding Apple employees:

PLEASE DO NOT “OUT” ANOTHER ATTENDEE AS A CURRENT EMPLOYEE OF APPLE, INC. Apple employees have greater freedom to share their expertise in-person if they remain unidentified.

Summary:

All attendees, speakers, sponsors and volunteers at our conference are required to agree with the following code of conduct. Organisers will enforce this code throughout the event. We expect cooperation from all participants to help ensure a safe environment for everybody.

The Quick Version

Our conference is dedicated to providing a harassment-free and privacy-forward conference experience for everyone, regardless of gender, gender identity and expression, age, sexual orientation, disability, physical appearance, body size, race, ethnicity, religion (or lack thereof), or technology choices. We do not tolerate harassment of conference participants in any form. Sexual language and imagery is not appropriate for any conference venue, including talks, workshops, parties, Bluesky and other online media. Conference participants violating these rules may be sanctioned, suspended, or expelled from the conference without a refund at the discretion of the conference organisers.

The Less Quick Version

Harassment includes offensive verbal comments related to gender, gender identity and expression, age, sexual orientation, disability, physical appearance, body size, race, ethnicity, religion, technology choices, sexual images in public spaces, deliberate intimidation, stalking, following, harassing photography or recording, sustained disruption of talks or other events, inappropriate physical contact, and unwelcome sexual attention.

Harassment includes photos, audio, or video recorded without consent. (Please join our volunteer photography team to co-create a responsible, privacy-forward approach).

Harassment includes behavior that disrupts the peace, enjoyment, and overall experience of other attendees.

Participants asked to stop any harassing behavior are expected to comply immediately. This includes harassing behavior that begins in reaction to harassing behavior.

Sponsors are also subject to the anti-harassment policy. In particular, sponsors should not use sexualised images, activities, or other material. Booth staff (including volunteers) should not use sexualised clothing/uniforms/costumes, or otherwise create a sexualised environment.

If a participant engages in harassing behavior, the conference organisers may take any action they deem appropriate, including warning the offender or expulsion from the conference with no refund.

If you are being harassed, notice that someone else is being harassed, or have any other concerns, please contact a member of conference senior staff immediately. Conference senior staff can be identified as they’ll be wearing branded clothing and/or badges.

Conference senior staff will be happy to help participants contact hotel/venue security or local law enforcement, provide escorts, or otherwise assist those experiencing harassment to feel safe for the duration of the conference. We value your attendance.

We expect participants to follow these rules at conference and workshop venues and conference-related social events.
