I have a swift project with a Watch companion.
Since the update of Xcode in 16.3 version after updating MAcOs , Watch OS, iOS to the latest version . It is quasi impossible for me to make Xcode work with my series 10 Watch. I have a lot of alert box, messages in the "device & Simulator" tool like this
Previous preparation error: A connection to this device could not be established.; Timed out while attempting to establish tunnel using negotiated network parameters.
And many message telling me that Xcode is preparing the Watch , then that it has lost the connexion.
I have to wait some minutes after EACH run of the App to test it again. This is very annoying .
Some of the alerts I have :
And the best to know , is that I can run the APP outside of Xcode , it works, Connects to the iPhone, fetch data and so. the iPhone sees the Watch without and problem.
Reboots can solve for a few minutes the problem. But that is not a solution.
