Could not launch "" failed to get the task for process ?

Question

Using Xcode 4.5.2 and building for iOS4 or newer, I get this message when building for my device (iOS 6.0.1 on 4s). I dismiss the dialog then relaunch the app on my device which seems to work. I am newer to iOS development, so I aplogize in advance if this is a silly question.

Thank you in advance for your help.

Thank you, yes it was. I changed it, still happening!?! I am guessing a newbie mistake here.... — a-coder, Dec 30 '12 at 04:28

My issue was using Distribution provisioning profile for signing the app, once I made a development provisioning profile, the app installed and ran on iPhone just fine.

Yayy this worked! So on code signing I changed the 2 Debug rows to "iPhone Developer" instead of "iPhone Distribution" which I had before. I didn't touch release. – Andrei Cristian Prodan Sep 18 '13 at 09:13

Yes indeed: I was using an adhoc profile for debug in [Build Settings]->[Code Signing]... Switched to development profile, and could launch – braden Oct 24 '13 at 14:43

Perfect! Can someone please pass the message on to Apple, to allocate some budget to giving some useful error messages for stuff like this!? – David van Dugteren Feb 04 '14 at 23:08

The answer seems to be "you need to fix your provisioning profile", but can happen for several reasons, as indicated by other answers on here.

In my case, I hadn't added a new device to an existing developer provisioning profile, so I just re-created the profile with the new device, and it worked!

In my case happens all time I add a new device ID then update the provision profile, download and "install it on Xcode 5".

To fix this:

Go to Xcode>Preferences>Account Tab>Select Apple ID>View Details>Refresh Button (Bottom left corner).
Reinitiate Xcode.

Start again the app, you will be able to test the app in the device.

Here's what my situation was and how I solved the problem:

I had been running the app from Xcode to my phone and all was fine
I switched to a different code signing identity (I had to change the bundle name also to match)
I ran the app to my phone and got the error. The app would install, but not open.
Did a bunch of stuff like Clean, close n open Xcode; delete the app from the phone. All to no good effect.

SOLUTION: turned the phone off n on.

Coincidence? I think not. :-)

XCode 6:

Just create provisioning profile for development and assing it to Project -> Build settings -> Provisioning profile

For upload you have to change provisioning profile for Distribution profile.
