try! Swift Tokyo 2024: LT event recap

Speed

Read the summary

This year’s try! Swift Tokyo was a big win for our team. Eight iOS members attended, and five gave lightning talks during our follow-up study session. The event took place from March 22 to 24, 2024, and was the first offline edition in five years. It was a major shift from our usual online meetings, and it helped us all connect in a real, face-to-face way. We brought in guests from the Manabi no Michi no Eki learning group and the Android team, making it a cross-functional event. With over 20 participants, it was lively and engaging. Even though rain and hay fever kept some people home, everyone who showed up had a positive, joyful energy. We also created a dedicated Slack thread, which saw over 150 comments in just one hour—proof of how much people wanted to discuss what they’d seen. Mori-san shared deep insights into SwiftUI and TCA, showing strong technical knowledge. The event included more foundational sessions this year, which helped solidify their understanding. Hinomori-san, who helped run the event for three days, shared behind-the-scenes stories and stood out during the closing ceremony. His work showed how much effort goes into organizing such events. Nakaguchi’s talk focused on visionOS, covering how to build apps with Swift and start developing spatial experiences for Apple Vision Pro. Though I haven’t worked on visionOS yet, the session sparked a strong interest. Ryomm-san gave a lively recap, emphasizing that simple things like saying “Hey there!” can open great conversations. Goseo-san tried out SwiftUI animations from a session and found some still-unresolved quirks—something that made the learning feel real and hands-on. Overall, it was a powerful experience. I’ve never attended an offline conference before, and it was both educational and inspiring. I now want to help organize future events, and I believe turning our participation into LTs and blog posts is a smart, sustainable way to keep learning alive.

 IntroductionHello. I am Nakaguchi from KINTO Technologies, Mobile App Development Group. I work on developing KINTO Easy Application App  and also organize study sessions and events for the iOS team.

Eight members of our iOS team attended try! Swift Tokyo 2024, which was held from March 22 to 24, 2024. Later, as part of our study sessions, we held LTs (lightning talks) to reflect on our experiences. Out of the eight participants, five gave presentations through LT, while the remaining three published articles on the KTC Tech Blog. Here are their blog posts:

 LT event detailsUsually, our team study sessions are conducted solely within the iOS team, but today we had guests including members from the "Manabi no Michi no Eki (roadside station for learning)", (more information here), who support company-wide study sessions, as well as members from the Android team.

With over 20 participants, it was a very lively event.

Here is the online venue! Everyone has a lovely smile! 😀 

Here's the offline venue! Due to the rain or possibly hay fever, many people were working from home that day, so the turnout was a bit low. However, everyone who came was smiling happily! 😀 

Additionally, we set up a dedicated thread on Slack during the iOS team’s study session, and everyone enthusiastically engaged in the discussion. It was a huge success, with over 150 comments in just one hour!
 First speaker: Mori-sanMori-san shared a wide range of impressions about the sessions they attended! It was also memorable that Mori-san expressed gratitude to the event staff and simultaneous interpreters.

I got the impression that Mori-san already has a deep understanding of SwiftUI and TCA, which are used in their work. This year's try! Swift had many sessions that delved deeper into the basics, which likely helped deepen their knowledge.

Here is a video of Mori-san's presentation! 
 2nd speaker: Hinomori-san (ヒロヤ@お腹すいた)Hinomori-san was involved as a staff member for three days and shared many behind-the-scenes stories with us! You can also check out his blog article here! It turns out that much of the setup around were actually done by Hinomori-san.

Over the three days, I saw Hinomori-san working as a staff member many times and seemed to be very busy. The scene during the closing on the second day, where all the organizers, speakers, and staff gathered on stage, was very moving, and Hinomori-san stood out among them.

Here is Hinomori-san's presentation! 
 3rd speaker: NakaguchiThis will be my LT. This year, I want to focus on catching up with visionOS, so in my LT, I also talked about
“Creating a visionOS app with Swift” (Day 1)
and “How to start developing spatial apps unique to Apple Vision Pro” (Day 3).

I haven’t had the chance to develop for visionOS in my work or private projects yet (and of course, I don’t have the actual device), but my desire to work with visionOS has increased tremendously!

Here is my presentation! 
 4th speaker: Ryomm-sanRyomm-san had already released a participation report on Zenn, and it was presented during the LT. (Released on 23<sup>rd</sup> March 👀...so fast!!) I participated in try!  Swift Tokyo 2024! https://zenn.dev/ryomm/articles/e1683c1769e259

Ryomm-san provided an overall recap of the sessions, as well as reflections on the sponsor booths and the after-party. With amazing communication skills, Ryomm-san exchanged information with many people, including the speakers! According to Ryomm-san, the trick to starting a conversation with the person next to you is courage and a friendly "Hey there!"!! In these kinds of events, probably everyone wants to talk to someone, so don’t hesitate to strike up a conversation. We should all follow Ryomm-san’s example 😭

Here is Ryomm-san's presentation! 
 5th speaker: Goseo-sanGoseo-san shared their impressions of the session “How to build a sense for designing good applications” (Day 1)!

They actually tried out the source code which was introduced during the session and shared their thoughts on implementing it with SwiftUI. It was enlightening to learn that animations in SwiftUI still have some quirks.

Here is Goseo-san's presentation (held on a different day, later) 
 ConclusionIt was my first time participating try! Swift, which was held for the first time in five years. I usually only attend conferences online, so this was my first offline experience. It was incredibly educational and a valuable experience. In the future, I would like to get more involved by participating as a sponsor or staff member. I believe it was a great initiative for our team to turn our participation in try! Swift into tangible outputs, such as LT events and blog writing. I hope we can continue these kinds of activities at future large conferences like try! Swift and iOSDC.
