Try! Swift 2016

On Wednesday 2nd March - Friday 4th March, I attended the first Try! Swift developers conference in Tokyo, Japan. As Apple’s new programming language begins to grow and mature it is now receiving a large amount of attention throughout the developer community. This conference was a great opportunity for developers of the iOS, tvOS, watchOS and Mac OS X platforms to present on the ways they are pushing the limits of the language. It has opened up many unique discussions on the ways the language itself can be improved, some of the drawbacks that exist and most importantly the best practices that have revealed themselves already within the community.

Leaving from Terminal 2 at Sydney Airport with a conference ticket I had only received days earlier off the waiting list, I had no idea of the experience I was in for and the great people I was about to meet. I sat contently in my seat somewhat rushed, fearful, nervous yet excited for my first trip to Tokyo.

We have already begun using Swift at Bilue with many of our clients and of course on our own internal projects. As a team we have been pushing ourselves forward, learning new things and working extremely hard to bring each other up to scratch on everything that Swift introduces. I'd decided that attending the conference was a great way to extend my learning and to exchange ideas with some of the leading developers from across the world.

It turned out that Tokyo was an amazingly beautiful place that seemed to deeply align with my passions on so many different levels. On the days leading up to the conference I found time to explore a few different areas, most notably my favourite place - Omotesando. I loved the quiet atmosphere and the subtle nature that seemed to somehow augment the buildings and the cityscape. I quickly learned this to be home to some of the finest coffee that Tokyo has to offer, including Blue Bottle Aoyama which was as amazing as its San Fransisco counterpart except without the long lines and hot sun.

For us Swift augments our design-led approach to building inspired products. It allows us to apply the core idioms of the Swift language into writing safer, more reliable and less error-prone code. Essentially, by writing Swift we can be more certain that our software behaves exactly the way we expect it to. By taking advantage of Swift’s protocol oriented approach to application architecture we end up building products that are far more maintainable for our clients long after we've touched them.

At the conference located in Shibuya Mark City, I attended countless talks that were each in their own way both insightful and intriguing. On the first day Syo Ikeda presented a great talk which dived deep into the broad Swift Ecosystem. Syo outlined the most popular frameworks, libraries, resources and tools that any decent Swift developer would need to know about. We also heard Laura Savino explore the intricacies and cross-overs of learning a new language, whether it be a new programming language or a spoken language. Gwendolyn Weston quickly wowed the audience with her well received and incredibly detailed use of Pokemon as an example of Swift Type Erasure.

One of the biggest highlights of my trip to Tokyo was being able to find and attend a Yomiuri Giants exhibition game played at Tokyo Dome. Despite all of the hilariously cruel difficulty I went through to get my ticket printed at the convenience store, I managed to get in. I played baseball when I was younger, and I've seen a game in San Fransisco, but now I know that baseball in Tokyo is like none other. Another memorable moment took place on the Tuesday evening before the conference, many of the speakers and attendees organised a visit to Roppongi Hills. At the top of the Tokyo City View we watched as the sun set over the skyline and this view was nothing short of breathtaking.

On the second day Adam Bell from Facebook asked a really great question, "When was the last time you used an app that felt surreal, or broke the laws of physics?" He presented his doubts about the plain, flat and lifeless modern iOS application and then discussed the ways prototyping can be used to implement rich, interactive and immersive animations using Swift.

Daniel Eggert explored how Swift allows developers to breathe an entirely new life into old and rigid but still tried and tested Cocoa APIs such as Core Data. Later that day Chris Eidhof similarly presented a more Swift-y approach to UITableViewControllers and demoed a really fun and unique keyboard shortcut animation technique.

Fish Market

Ridiculously early (at about 5:00am) on Thursday morning a friend and I woke up and made the trek down to the Tsukiji fish market. I'd been told that this well known fish market will be relocated really soon, so I was really glad that I took the chance to go while I could. It was a fast and intense experience with motor scooters carrying fish barrels zooming past us, it was really obvious that we had no idea where we were or what to do. Nonetheless I managed to take some really nice photos that made the early morning well worth it.

A standout talk on the final day of the conference was the excellent talk presented by Jesse Squires from Instagram on contributing to Open Source Swift. Jesse gave a really in-depth and well thought out, yet clear and simple understanding of the Swift project structure. He told us exactly how the Swift code we write in Xcode is compiled into a binary for release to the App Store. He provided a perfect guide and recommendation on contributing to the underlying Swift library at any experience level and with any skill set. Most importantly he outlined the importance of making Swift into a language that the community as a whole can enjoy and use productively.

Swift is more than a programming language. Swift is a community!

Another great talk was Ash Furrow’s overview of the Artsy approach to testing. Ash breaks down the different approaches to each of their apps based on which approach (or lack of!) they took and how it affected the team and the product itself. I really appreciated seeing Ash give this talk and outlining the balance that is required when implementing BDD (Behaviour Driven Development) or TDD (Test Driven Development) with tight deadlines and uncontrollable circumstances. He mentioned the Snapshot approach to testing, which is definitely something that I will be taking a look into and experimenting with.

There is no other way to say it than this - I met so many amazing developers and people at Try! Swift that I just know I'm going to be really great friends with for the rest of my life. It underlines exactly why I chose to become a software developer, and exactly why I believe software creates opportunities that make the world a much better place to be.

A takeaway for me from the conference was that for the foreseeable future Swift is at the bleeding edge of the Apple Developer Community. And as has come to be expected, Swift is taking shape in the form of a strong, powerful and great community. There are so many developers learning Swift together right now, each and every one pushing the boundaries of the language making it a greater language to build amazing things with over time. Swift has the potential to greatly improve our development experiences at Bilue as well as to ensure that the inspired products that we create truly fulfil their purpose for the people that use them.

We intend to continue working hard on writing Swift and will post some of our thoughts, experiences and code here as we go. Thank you to everyone who organised Try! Swift, which turned out to be an amazing conference in a beautiful city bringing together some of the smartest minds from around the world.
