Xcode "Could not launch". Only reports "Security" as error

Question

I've edited the app name out. Other than that the dialog is exactly like this. I'm developing an enterprise app and I've tried restarting xcode and the iPhone I'm developing on. No change. Anyone encountered this? Are there any log posts that could point me in the right direction or get me more details. There is nothing in the regular log from what I can see.

Update

Found this in the device log:

<Warning>: Unable to launch com.bundleID.etc because it has an invalid code signature, inadequate entitlements or its profile has not been explicitly trusted by the user.

Which is a bit weird since it worked yesterday and all profiles etc. were issued a week ago.

Solution 1

Apparently after upgrading the OS and such you must manually launch the app on the device and say that you trust the developer of the software.

That error message disappeared now.

Solution 2

Using xcode 7 with an iOS device running version 9.2, I had to:

1. Open 'Settings'
2. Tap 'General'
3. Tap 'Device Management'
4. Tap 'Developer App' that's in the list
5. Tap 'Trust (developer name)'
6. Tap 'Trust' in the popup

The app should load and launch when you run xcode.

Solution 3

I just got this issue running on an iOS 8 device for the first time as it required me to launch manually on the device (it copies it fine but doesn't launch it) and then state that I trust the developer.

Solution 4

I had the problem of not having the app on my device, so I couldn't manually launch it to accept the prompt. For me, I got this to work after deleting all expired provisioning profiles from my device, which forced Xcode to install a new one.

After this, I was able to get my app to run.

Solution 5

I had the same issue solved like this:

It can be happen because your developer profile is not assigned as TRUSTED in your phone or watchos settings.

You can set your profile as TRUSTED as below:

• Go to Settings,
• Profile
• Assign your profile as Trusted there.

I seriously tried to click the OK button a few times :|

It happened when my iPhone is in offline. When I clicked the app it shows an alert like Title: "Unable to Verify App" . Description: "An internet connection is required to verify trust of the developer "About the certificate" . This app will not available until verified." This means we need an online connection to verify the app'

The "has not been explicitly trusted by the user" part of the device log made me think. Then I just poked around for a bit and when opening the app asked for consent. I remembered the "explicitly trusted by the user" part and thought that might be it. It was.

The "failed to get the task for process XXX" is likely because you are using an Enterprise provisioning profile (or a Distribution provisioning profile) and not a Developer provisioning profile.

[Ricardo Sanchez-Saez]

This method stops working if you delete and reinstall the app (which is sometimes needed for clearing all caches, etc.). As perk @Mark answer, deleting all your phone provisioning profiles is a more permanent solution.

For me, uninstalling the app from device, doing the above, then installing the app worked for me.

ya, this need to be set at iphone manually and the hints will be displayed when you click on the app in iPhone

[Andy Weinstein]

I think I needed to do both this and the answer below about Trusting

[Adam Smaka]

@AndyWeinstein yeah but the latter one is obvious
