iPhone is busy: Making Apple Watch ready for development

Since I upgraded to iOS 15, watchOS 8 and Xcode 13, after I turned off and on my Mac, every first time I want to launch an app from Xcode to my iPhone appear this message (even if I'm not developing for watchOS):

iPhone is busy: Making Apple Watch ready for development

The Mac stays stuck on it for at least 20 minutes.

The only solution I found (until now) is to switch off WiFi on my Watch.

Is there a better solution?

  • I had the same problem! iphone tries to activate my apple watch 1 to no avail and they both download in half a day! How can I solve this problem? This prevents me from testing the apps in progress on XCODE because iphone is stale.

  • same problem here. Very annoying. Slowing down my development work considerably. Please fix

  • Quite frustrating, any chance we can get this fixed for the new year? Driving us all bananas.

Turning off completely Bluetooth (Settings -> Bluetooth -> Off) forced any reconnect attempts or limbo state to go away, and then I could proceed with building my project :-)

I got same problem with Latest Version of iOS and watchOS. When I quit Xcode, reopen Xcode and retry the build, it solved.

Same problem here. I tried turning on/off everything as suggested in this thread, even un-paired my Watch from iPhone. Nothing worked. Spent 5 hours trying to rectify.

And then I finally found a solution: I cleared the /Users/me/Library/Xcode/DerivedData directories for my app. (ie, any directory which begins with your app name.) That did it. Could have saved myself a 1/2 day of programming if I had tried that 1st.

YMMV
