Will this problem ever be solved? The Apple Watch was released in 2014 — it’s now 2025, and this issue still hasn’t been fixed. Maybe that’s why there are so few apps for the Watch: because the debugging process simply doesn't work properly. I’ve been struggling with WatchConnectivity for three weeks. I need to use transferFile, but it doesn’t work on the simulator. I sit for 8 hours a day staring at the message: "Previous preparation error: Transport error." Once in 200 attempts, Xcode might manage to launch the app on a real Watch — and even then, the connection drops within 10–15 seconds. Not a single one of the thousand workaround tips fixes the problem. Endless reboots of my Mac, iPhone, and Watch; switching Wi-Fi and Bluetooth — it’s all useless. Maybe you could finally release a Watch that can be connected via a cable? Maybe that would solve the problem?

Reproduced in ios 26 beta 5

Try this: if #available(iOS 26.0, *) { self.navigationItem.searchBarPlacementAllowsToolbarIntegration = false } it helped me.
