Those Who Swift - Issue 214
Weekly note ✏️This week’s issue is packed with hidden features, overlooked vulnerabilities, and deep dives into Apple’s architecture. In the video section, don’t miss a gripping breakdown of how Apple allegedly leaves extra room for its own apps and features to shine—often at the expense of third-party developers. It’s a frustrating reality, even for large companies. Framework owners may claim neutrality, but many decisions seem guided more by business strategy than by user-first thinking. Still, the tables do turn. The more transparency we gain—from researchers, developers, and investigative journalists—the more pressure mounts. Slowly but surely, even the biggest systems start to evolve, sometimes in small but meaningful ways. Change doesn’t always come from loud announcements. Sometimes, it starts with someone noticing the little things.
