Xcode process launch failed: Security

Question

I have been developing an app for 1 or 2 weeks now and just yesterday I have updated my iPhone 5S to the iOS 8 GM. Everything worked fine and I could test on my device as we

Answer 1

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 ;-)

Answer 2

Alternatively if one does not see "Untrust App Developer" dialog:

Go to your iPhone > Settings > General > Profile > "you@email.com" > Trust

Answer 3

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 & Run again.

As from iOS 9, it is required to go to Settings → General → Device Management → Developer App → Trust`.

On some versions of iOS, you will have to go to Settings → General → Profile instead.

Answer 4

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 & launch this and your other apps.

Answer 5

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

Answer 6

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 :)

1. Run the app via Xcode. You will see the security alert below. Do not press OK.

2. On your iOS device, tap the newly installed app icon:

3. 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.

4. 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.
