as the organisers put it
Developers from all over the world will gather for tips and tricks and the latest examples of development using Swift. The event will be held for three days from March 2 - 4, 2027, with the aim of sharing our Swift knowledge and skills and collaborating with each other!
who it's for
Swift developers, iOS developers, systems and compiler engineers, mobile machine learning engineers, backend and server engineers, tooling and developer experience engineers, AR and interaction designers

Implementation of super resolution with CoreML converting low-res manga to high-res runs fully on-device, exporting a custom-trained SRCNN model that restores… | ||
| SwiftyPi | Kate Castellano | 18m |
Raspberry Pi runs Ubuntu 16.04 and hosts a Vapor server while Swift code on the Pi is limited to Swift 3.1.1 (no ARM support for Swift 4.x), so the build uses… | ||

Kotlin shows concrete, Swift-friendly parity: val vs let for constants, identical optional syntax that reduces null crashes, and familiar generics plus… | ||
| Writing Blockchain Clients in Swift | Tamar Nachmany | 21m |
Current iOS options require using Java, JavaScript, Go or generated Objective‑C bindings (examples: web3js, web3j), or embedding WebKit/React Native; there is… | ||
| AST Meta-programming | Kishikawa Katsumi | 27m |

| Codable Routing with Kitura | Pushkar Kulkarni | 21m |
Kitura 2.0 takes JSON duties off handlers so routes accept and return Swift types directly, cutting boilerplate and leaving only business logic. Examples… | ||

| Finally Solving the Expression Problem | Brandon Kase | 19m |
Claims a practical solution to the expression problem in Swift by using protocols whose methods return Self so view constructors become static factory methods… | ||
