I've been developing an app for a while and I haven't had any problems running the app on the device.. now a few days ago, whenever I connect the iPhone, it plays its little "ka-chink" sound and shows up in Xcode, but after a few seconds it disconnects and reconnects with another "la-chink" and keeps doing this until I want to throw it out of the window.
Of course, it's not possible to debug on the device with the constant disconnections, so I just:
I've tried various thing to get the phone to work properly again but to no avail so far.. anybody experienced this? any solutions?
Update: cable and connector fine, no hardware trouble.

Connect to the Mac from Visual Studio 2022Open the Pair to Mac dialog with the Pair to Mac button iOS toolbar: Alternatively, select Tools > iOS > Pair to Mac. The Pair to Mac dialog displays a list of all previously connected and currently available Mac build hosts: Select a Mac in the list and select Connect.
A solution to the issue of iPhone rapidly disconnecting from a Mac that has worked for many is stopping the usbd process. To do that, open the Terminal app from Spotlight (Command+ Space) and enter the command sudo killall -STOP -c usbd.
I think this is not the problem with the device/Mac port/USB cable.
This seems to be an issue with usbd in Mac OS. The following can solve the issues:
Open Activity Monitor -> View -> All Processes -> Search for usbd -> Double click -> Quit -> Force Quit
Using terminal:
sudo killall -STOP -c usbd will pause the issue related process
If you want to resume the process for any reason use the following command
sudo killall -CONT usbd
This solution is working in MacOS Catalina as well.

In the end removing expired certificates (current ones were already installed) solved the problem.
