Xcode 11 "iphone is busy: Making iphone ready for development"

Question

I have been waiting 2 days now, and the xcode "Devices and simulators" window is still hung with the message "myiphone is busy: Making myiphone ready for development".

1. I have connected this phone to xcode and uploaded apps many times before
2. I have not updated ios nor macos recently

I have tried the usual suspects:

1. waiting. 5 hours so far.
2. disconnecting phone, restarting xcode
3. rebooting phone.
4. rebooting mac
5. checking under general-device management, nothing new there.

versions:

• xcode 11.2
• 2017 mb pro 512 quad. 16GB
• mac 10.14.4 (I can never upgrade beyond this due to need for 32bit drivers).
• ios 13.3.1
• iphone storage: 51GB of 64GB used.

I also frequently get the issue that when I connect the iphone the device managers says its locked, but it is not locked. In this case, I disconnect device, restart xcode, reconnect the device while xcode is running, which fixes this common issue.

Answer 1

Oh my, that is weird! And annoying. I had the same before, here is what I tried, in addition to your things:

• Clean Build
• Wiggle the cable (or use different port, one was faulty)
• Try buiding via wifi instead of cable
• Remove the phone from device-manager and "trust" it again

Answer 2

In devices manager click unpair as shown in this screenshot.

Then in your iphone click trust and the issue is gone.
