Have you ever built a socket communication app? The sense of accomplishment when you delve into layers that aren’t typically touched in your everyday app development and actually utilize them in an app is truly exceptional. However, creating a socket communication app requires knowledge of POSIX sockets, and for complex communications, you need to implement parallel processing.
In this talk, we’ll implement socket communication and parallel processing in Swift. With Swift, which we’re all familiar with, you can easily venture into unfamiliar territories, and there are several instances where you can leverage Swift’s capabilities through implementing socket communication and parallel processing. Take this opportunity to enjoy learning socket communication and rediscover the charm of Swift!

@twostraws

After transitioning to remote work several years ago, I found myself spending most of my time at home. However, I wanted to ensure I maintained a healthy lifestyle by aiming for 10,000 steps per day. To easily track my daily steps without the need for an app store, I developed a personal app for myself.

Initially, I experimented with an iOS app using Swift Charts. However, as updates to the operating system rolled out, I found that I rarely used the app. Instead, with the convenience of the Apple Watch widget, I seamlessly transitioned to tracking my steps directly from my wrist. I’ll discuss the logical progression of how I continuously refined the app for personal use, adapting it to evolving OS features, and how it positively impacted my daily routine.

Macros are little compiler plugins that allow us to extend the Swift language in ways that do not require going through Swift evolution, or waiting for a Swift core team member to implement the feature, or require us learning C++ so that we can try implementing the feature ourselves. It is an incredibly powerful new feature, but can also be incredibly complex to get right. Let’s explore how to debug and test every aspect of macros, from the code they expand to, to the errors and warnings and fix-its they emit.

@himeshi_tech

In a world increasingly dominated by Artificial Intelligence (AI), this presentation challenges the audience to consider an alternate future: one where AI is not the centrepiece of technological advancement. We delve into the implications of a future less reliant on AI, discussing the potential benefits and drawbacks.

The talk focuses on three key areas: human creativity and innovation, the preservation of traditional skills and knowledge, and the ethical considerations of a non-AI-centric world.

Firstly, we explore how a reduced emphasis on AI could foster greater human creativity and innovation. Without AI’s influence, there might be a resurgence in traditional problem-solving approaches and a renewed emphasis on human ingenuity.

Secondly, the talk addresses the preservation of traditional skills and knowledge. In a world less dependent on AI, these skills might not only survive but thrive, leading to a more diverse technological landscape.

Finally, we discuss the ethical implications of a world without pervasive AI. This includes considerations of privacy, employment, and societal structure, and how these might differ from a future where AI plays a central role.

With iPhones continually advancing their camera capabilities, one can capture satisfying photos without the need for a dedicated digital camera. Yet, there exists a niche of individuals who intentionally purchase older digital or film cameras. They are drawn to the unique aesthetic of photos and videos produced by these cameras.
In this talk, we’ll explore how to achieve such retro-style photos using Swift. While Core Image’s documentation offers articles like “Simulating Scratchy Analog Film,” implementing these techniques directly into a camera app may not yield the desired retro effect. Therefore, we’ll start by reexamining the question, “What defines a retro-style photo?” and aim to create the ideal retro aesthetic.

Swift boasts a powerful language feature known as type inference, which is crucial for balancing a safe type system with ease of coding.
Understanding how this essential feature is implemented can aid in writing better code.

In this talk, I will explain the workings of Swift’s type inference, including the fundamental algorithm that allows bidirectional propagation of type information for code, and how it’s extended to accommodate language features like overloading.
This will help understand why compiling code can become overly burdensome and result in errors.
I will also cover interesting related topics such as overload priority, simultaneous inference in multiple statements, and the challenges of protocol compliance determination.

Additionally, methods for directly observing the behavior of type inference using compiler options will be introduced, paving the way for further deepening your understanding.

Localizing your app into other languages can unlock a huge amount of growth potential for your app. But as an indie developer, I don’t have time to spare and don’t have others I can rely on to do the work involved in maintaining a high quality localization. So, I rely heavily on automation to minimize the work associated with maintaining 8 different high-quality localizations in my app Nihongo.

In this talk, I’ll discuss what aspects of localization I entrust to professional translators, what I use machine translation for, and what I use crowdsourcing from social media for. I’ll discuss techniques for automating various aspects of the localization process, including (1) generating screenshots of strings for providing context to translators and validating their translations, (2) generating app store screenshots, including marketing copy in multiple languages, (3) generating meaningful release notes in multiple languages, and (4) verifying app layout and correctness in multiple languages.
