Fixing Xcode 9 issue: "iPhone is busy: Preparing debugger support for iPhone"
Solution 1
There are multiple solutions for this:
Solution 1: Patiently wait for 10 to 15 minutes. Have a tea or roam around ;-)
Solution 2: Disconnect device from the system. Restart both iPhone and Xcode and then rebuild again.
Solution 3:
-
Go to Windows → Devices and Simulators (Shortcut key: cmd+shift+2)
-
You’ll see iPhone device connected to system with message
iPhone is busy: Preparing debugger support for iPhone
-
Click on plus button (+) present in bottom-left corner.
-
This will show the device connected to system. Click on Next button.
-
Thereafter you’ll see ‘device setup was successful’. Click on Done button.
Solution 3 worked for me!
Solution 4:
Unpair your device and then pair it again. Thereafter follow Step 3.
Solution 2
I clicked ‘Cancel Running’, opened the Devices list, unpaired my iPhone, removed my USB cable and reconnected it, paired the iPhone, and then was asked on my iPhone to enter my passcode ("pin code"). Did this and then was finally able to pair my phone correctly.
Solution 3
Wait a few minutes. The application will start automatically
Solution 4
Restarting Xcode worked for me (quit and start again).
What didn't work for me:
- waiting for an hour on one device
- waiting for an hour on another device
- restarting devices
- unpairing/pairing devices
Solution 5
It turns out XCode opens device manager window beneath it and waits for you to hit the next button. Switch to that window, hit next and you get the progress bar for the process to show up.

When people asked me what I wanted to do for work 10 years ago, I did not know too well, so I just said "Something to do with computers". As I look at the last 10 years, I see that I did quite a lot of work all kinds of computers. From fiddling with microcontrollers and assembler code to writing data processing scripts to physically assembling computer consoles. The big step forward came when I learned to think about software in a structured, object-oriented way, as this allowed me to make software do things that I want it to do. Right now I'm proficient in two high level programming languages - Objective-C and Java and have touched just about every framework available for iOS. I've also became a hacker/maker and have completed a number of projects involving software and hardware. Right now I'm in my early 30s and when I ask myself "What would I like to do in the next 10 years?", my answer is "something with the human brain". The seeds are already there - I've picked up an interest in biology, cognitive science and neuroscience, enough to converse with real people. I've done first-hand research into sleep and made discoveries. I've taken classes in synthetic biology, performing manipulations on the bacteria genome. I've learned a lot about the neurotransmitter systems of the human brain, as well as how a biological organism develops. It seems like there are a lot of similarities between the object-oriented concepts I use in the daily programming tasks and how biological organisms operate. This makes me hopeful that by the time I'm in my late 30s, I would be able to work and program some form of biological computer or just plain hack the human brain.

I'm looking for more information on the message below. Xcode 9 seems to be hanging for a couple minutes already...
How can I tell Xcode 9 to quickly recognize my previously used device updated to iOS 11?

Xcode will continue when .Alex’s iPhone is finished.
