Xcode doesn't see my iOS device but iTunes does

Question

I have a strange problem.

I have an iPad with iOS 5.0.1 (9A405) and iOS SDK 5.0.1 with Xcode 4.2 (Build 4C199) installed on my Mac.

Xcode doesn\'t see my dev

Answer 1

The error I had in XCode was "iOS version lower than deployment target", which I didn't know how to fix. The error was displayed where the iPhone should have been indicated as a Device (upper left). I selected the project in Project Navigator and noticed that the iOS Deployment Target was set to 11.3 but when I checked my iPhone it was set to 11.2.1 (or something lower than 11.3). So I opened Settings on the phone, scrolled down to General and tapped Software Update. Since the update said it was scheduled but didn't start, I decided to take the SIM card out of my other phone and put it in the iPhone I was using for testing. Then the upgrade started quickly. After the Update finished on the phone, however, XCode still didn't recognize the phone. I unplugged the USB cable but didn't hear any sound, so I plugged it into another USB port on the computer and then heard a sound. Then XCode noticed the phone. So the problems were that the iPhone didn't inform me that I had an Update (or I ignored it and forgot about it) and it may have needed the SIM card, and I had a bad USB connection.
