I had this problem after I created a new developer certificate.

The following was already correct: The old private key was deleted from the keychain, all profiles where up to date, the build configuration and signing settings were correct. Yet I had this problem.

Solution: I had to restart Xcode (5.1.1), because it was not aware of my new developer certificate. I also deleted the obsolete profiles from my devices just to be sure and to clean up.

If you ve set the correct code signing certificate under Build Settings- Code Signing  then make sure you are also using the correct provisioning profile for Debug Release mode as well   I was having this issue because I was using an Ad-Hoc provisioning profile for both Debug Release modes  which doesn t allow for a development profile to be used when doing a debug build

Having the developer code signing id is correct for sure  but also make sure you device is added to the Member Center via organizer  or through the developer portal   A few days ago I reset my device list  and today I was suddenly getting this for an iPod I debug with all the time   About 15 mins later I realized the problem

Just get the same problem by installing my app on iPhone 5S with Distribution Profile  -  my solution was to activate Capabilities wich are set in Distribution Profile in my case  Keychain Sharing   In-App Purchase  and  Game Center    Hope this helps someone

I am betting that your release mode includes compiling with your distribution certificate  which disallows this behavior  you wouldn t want some random fool hooking into your app after downloading it from the app store    Compile with the development certificate instead   You can change this in the building settings under code signing

I had this same problem  however in a little bit different situation  One day my application launches fine  using developer provision   then I do some minor editing to my Entitlements file  and after that it stops working  The application installed fine on my device  however every time I tried to launch it  it exited instantly  after the opening animation    As I made edits to other files too  I did not suspect the following problem   The problem was in the Entitlements file format  seems so that the following declarations are not the same   Correct    lt key gt get-task-allow lt  key gt   lt true  gt    Incorrect    lt key gt get-task-allow lt  key gt   lt true   gt    Altough it s an XML format  do not use spaces in the  tag or the Xcode will not be able to connect to the process   I was using developer provisioning profile all along   Edit  Also make sure the line ending in your Entitlements file are  n  LF  instead of  r n  CRLF   If you edit the entitlements file on Windows using CRLF line endings may cause your application to fail to launch

If anyone is having this issue but is sure they have their certificates and code signing correctly set up  check the capabilities tab when you click on the project  i e  next to build settings tab  build phases tab  etc    In my case there were broken links for Game Center and In-App Purchases that needed fixing  by clicking the  fix me  buttons  to solve this issue

I switched back to  Automatic  on the build settings provisioning profile for  Debug  and left the release certificate profile unchanged  mine worked  Tried the other answers  nothing worked  Didn t want to have to reconfigure my certificates  Automatic on the provisioning profile did the trick

To anyone who comes across this  After reading this  I attempted to solve the problem by setting the Debug signing to my Development certificate only to find that deployment was still failing   Turns out my target was Release and therefore still signing with the distribution certificate - either go back to Debug target or change the release signing to Development temporarily
