I'm developing an app for Apple Watch, but I can't connect the Apple Watch to Xcode when I try to run the app on the actual device. I get the following errors:
A networking error occurred The device rejected the connection request
and
A connection to this device could not be established. Timed out while attempting to establish tunnel using negotiated network parameters.
The iPhone connects to Xcode without any problem.
I've already tried several things without success:
Resetting the "trusted computers" settings and trusting the Mac again Restarting all of the devices Making sure all devices are on the same Wi-Fi network
On the iPhone, I can see the Developer Mode toggle in Settings, but on the Apple Watch there doesn't seem to be a Developer Mode toggle at all. I'm wondering whether enabling Developer Mode is required in my case.
Could anyone tell me how to enable Developer Mode on Apple Watch, or suggest any other way to resolve this issue?
Here is my environment:
Mac mini (M1, 2020), macOS Tahoe 26.4.1 Xcode 26.4.1 Apple Watch SE 3, watchOS 26.1 iPhone 13, iOS 26.5
Thanks in advance for any help.
