Xcode Error: Failed to Prepare Device for Development

Xcode error: Failed to prepare device for development

A simple phone restart will fix it

I have had to come back to this SO question twice in the past couple weeks. First time, I did have to update my Xcode and iOS versions, which fixed the issue. Now, the issue has returned, but there are no updates. I tried disconnecting and reconnecting my phone from my laptop, but to no avail.

What fixed it the second time was merely restarting my phone. I am curious if that would have fixed it the first time too, without needing to have updated.

I know this is just echoing the other answers here, but at the very least, I would recommend just starting with a simple phone restart and seeing if that fixes your problem. Here is the specific screenshot that I encountered, in case yours is the same (pro tip: you can open up the "Devices and Simulators" window by going to Window -> Devices and Simulators shift-command-2).

Failed to prepare device for development. XCode 13.2.1, iOS 15.1

This answer helped me where you:

• Open XCode and device manager
• Connect the device
• Shutdown the device while being connected
• Power on the device
• Wait till the device is processed by XCode in devices and simulator window

I deleted deriveddata and it worked.

Error in Xcode after adding DeviceSupport: Failed to prepare device for development

I didn't find a workaround, so I simply downloaded the Xcode beta version, opened it, build the app to the iPhone and then deleted the beta version, since I only needed it for this one build.

You need to update the software on your phone to the latest and the xcode to the latest versions
