Since its debut in June 2023, SwiftData has fundamentally changed how Apple developers approach persistence. Devs the world over love it for its versatility, its declarative ease and its powerful querying system. But if you’re new, SwiftData can take some getting used to. Failures can feel less transparent and relationships can play out differently to how you might expect. So in this tutorial we’ll show you how SwiftData works and how to.

In an API-driven setup, a gateway often sits between clients and backend services: it can validate input, aggregate upstream responses, and give you one place to observe traffic. Koa is a strong fit for that role. Its core stays small, async/await is first-class, and middleware composes in a predictable stack. In this article, you will build a compact API gateway with Koa that: You will also wire up AppSignal for the Node.js stack.

The online learning explosion has exposed a massive gap… The numbers are staggering. The global e-learning market, valued at approximately USD 299.67 billion in 2024, is projected to surpass USD 842.64 billion by 2030, growing at a CAGR of 19.0%.

The challenge of any aerospace company is to deliver new capabilities without compromising safety, reliability, or precision. At our current juncture, legacy technology runs into conflict with modern tool stacks. Artificial intelligence (AI) creates fissures in compliance and auditability, and innovation and productivity gains come at a cost of greater complexity. Despite these seismic shifts, the central question remains the same.

It happens to all of us. As software projects grow, parts of the production code we ship end up without a comprehensive test suite. When you take another look at the same area of code after a few months, it may be difficult to understand; even worse, there might be a bug, and we don't know where to begin fixing it. Modifying production code without tests is a major challenge.

Choosing between building and buying real estate software isn’t just a technical decision—it shapes how fast you move, how much control you keep, and how far your product can scale. Whether you’re launching a PropTech startup or modernizing an existing real estate platform, the wrong choice can lock you into costly limitations, while the right one can become a competitive advantage.

Push notifications are one of the most powerful retention tools in mobile. iOS opt-in rates average 40–45%, and apps that use push effectively can triple their long-term retention. However poorly timed, poorly crafted alerts can drain our open rates, leading to opt-outs and disengagement. When designing iOS push notifications, we need to think about engagement and retention, not just impressions.

A guide to learning how MCP registries help govern AI agent-to-tool connectivity AI agents are only as capable as the tools they can reach. When an agent needs to query a database, file a support ticket, or pull data from a CRM, it has to find the right tool, authenticate, and invoke it — all at runtime. The Model Context Protocol (MCP) standardizes how agents communicate with these tools. But MCP alone does not answer a fundamental question: how does the agent know which tools exist?

Roughly 35 million commercial vehicles are operating across the world's top logistics markets today. Every one of them is burning fuel, accumulating wear, and navigating roads that are more congested, more regulated, and more expensive to operate on than ever before. The numbers behind inefficiency are staggering. According to the Department of Energy and the Argonne National Laboratory, 6 billion gallons of gasoline are wasted by idling alone every single year.
