Retail

This page brings together practical insights for teams modernizing or expanding digital systems in the retail industry. You’ll find real examples of how retailers strengthen online and in-store experiences through better product catalog management, inventory automation, POS integrations, and end-to-end omnichannel workflows. The content here covers how engineering teams address challenges like high-traffic eCommerce performance, faster checkout flows, mobile shopping journeys, and the shift toward data-driven personalization.

As you explore these resources, you’ll get a grounded understanding of what matters when hiring developers for building retail software solutions—from experience with secure payment flows and ERP/CRM integrations to comfort with storefront performance tuning, loyalty systems, and scalable backend architectures. And whenever your team needs additional capacity for upcoming retail initiatives, you can review vetted developer profiles or schedule interviews to bring the right expertise on board.

RealityKit Swift 6 Concurrency Fix: Solving Sendable & postProcess Threading Issues

RealityKit Swift 6 Concurrency Fix: Solving Sendable & postProcess Threading Issues

While building a retail AR experience, we encountered data races in RealityKit’s postProcess callback. Because the closure is assigned on the main thread but executed on the render thread without a @Sendable annotation, strict concurrency issues arise. Here is how our team solved this architectural mismatch.
