iPad grayed out in Instruments target selection
instruments, ios, xamarin.ios, xcode
Solution
Make sure that:
You're using the latest stable Xcode 4.5.x (or newer) since you're targeting the latest iOS stable release;
Instruments was started by Xcode, e.g. an old Instruments (from Xcode 4.2) can be started independently (e.g. by spotlight) and might not support iOS 6.0.1. In doubt check Instruments version;
Your device is configured for development (look at it inside Xcode organizer, devices);
Your device's provisioning profiles and developer's identity/certificate are up to date;
Note: you should edit your question and add the XCode version number you're using.
Problem
I'm trying to profile an iPad app in Instruments, but regardsless of which profiling settings I choose, I cannot select the iPad as the profiling target: If I hover the mouse on "Attach to Process", the only thing I see are grayed out entries for "Application" and "System". Any hints on the reason why I cannot use Instruments on the iPad?
