In iOS 9 2 they renamed the  Profiles  to  Device Management   This is how you should do it now    Settings -  General -  Device Management Verify the app

If you get this  the app has installed on your device  You have to tap the icon  It will ask you if you really want to run it  Say    yes    and then Build  amp  Run again    To add to that  this only holds true the moment you get the error  if you click OK  then tap on the app  It will do nothing  Scratched my head on that for 30 odd minutes  searching for alternative ways to address the problem

Update for iOS9 2 1 and Xcode 7 2 1  If you get this error when building to a device in Xcode      On your device  tap the app icon that would have just been added from your attempt at building the app and you should see this     Next  on your device  go to Settings --  General --  Device Management  and you will see this page     Select the profile you are using with Xcode  and you should see this page    Click Trust  username email com  then click Trust on the next popup   Go back to Xcode and re-run your project and it should build the app to your device

Xcode is able to build and install the app  but isn t able to launch it the first time  You just need to tap on the app s icon on the phone  then you will be prompted to ask if you want to trust the developer  Allow it and the app will launch  then Xcode will be able to automatically install  amp  launch this and your other apps

To get around the process launch failed  Security issue and immediately launch the app on your device  tap the app icon on your iOS device after running the app via Xcode   This will allow you to immediately run the app  It may not actually  fix  the root issue that is causing these permission alerts   Be sure to tap the app icon while the Xcode alert is still shown  Otherwise the app will not run  I continually forget this vital step and am unable to run the app on my device  Thus I am documenting it here for myself and everyone else      Run the app via Xcode  You will see the security alert below  Do not press OK       On your iOS device  tap the newly installed app icon       After tapping the icon  you should now see an alert asking you to  Trust  the Untrusted App Developer  After doing so the app will immediately run  unconnected to the Xcode debugger    If you do not see this  Trust  alert  you likely pressed  OK  in Xcode too soon  Do not press  OK  on the Xcode alert until after trusting the developer        Finally  go back and press  OK  on the Xcode alert  You will have to re-run the app to connect the running app on your iOS device to the Xcode debugger

BTW  this also happens if you change the team of your target in Xcode and rebuild  Was quite puzzled to see that problem with an app that I had run on the device before  Took me a while to figure out    Might only happen the first time building to a device with a team  though

Hey so the accepted answer works  except if you need to debug the initial launch of the app  However I think that answer is more of a work around  and not an actual solution  From my understanding this message occurs when you have some weirdness in your provisioning profile   cert setup so make extra sure everything is in tip-top shape in that dept  before ramming your head against the wall repeatedly  What worked for me was as follows from the apple docs   Provisioning Profiles Known Issue If you have upgraded to the GM seed from other betas you may see your apps crashing due to provisioning profile issues  Workaround   Connect the device via USB to your Mac  Launch Xcode Choose Window - gt Devices  Right click on the device in left column  choose  quot Show Provisioning Profiles quot   Click on the provisioning profile in question  Press the  quot - quot  button Continue to removing all affected profiles   Re-install the app    Make sure you right click on the image of the device not the name of the device or you won t see the provisioning profiles option  I restored my new phone from an old backup and there was a lot of cruft hanging around  i also had 2 different dev  certs active  not sure why  but i deleted one  made a new profile got rid of all the profiles on device and it worked  Hope this helps someone else

Updated answer for Xcode 7  Tapping the app no longer works  as of beta 1 it just displays an  untrusted enterprise developer  message with only a Dismiss button    To fix  open the Settings app  go to General   Profiles  and you ll see your profile  Mark it trusted and things should start working normally again   Updated For iOS 9 2 1 and Xcode 7 2 1   Goto  Settings   General   Device Management   Select App from Developer Apps   Trust App

SETTINGS -   GENERAL -  Profiles  amp  Device Management choose the developer profile and push Trust   if you do not have Profiles  amp  Device Management menu you have to enroll your device on beta apple com and download the profile from Safari    install the profile  Restart your device tap on the developer profile and trust    You are all set

I have the same issue  I click ok in xcode and when launching the app on my iPhone I m asked if I want to trust this application  Doing it  the app runs and further build-and-run from xcode went without any issue until deleting the app from the iPhone and reinstalling it  Then goto first line  -

Ok this this seems late and I was testing the app with internet connection off to test my app for some functionality  As I turned off the internet it gave me such error  After I turned on the internet I can install again  I know this is silly but this might be helpful to someone
