iOS 12 iPad Denied Launch Request - Xcode

Question

I've been updating an application for more than 5 years without problems, until yesterday.

I updated my iPad to iOS 12, but, each time I try to run it, I got the message:

iPad has denied the launch request

I tested in other physical devices with iOS 11 and simulators, and this error happens only with the devices with iOS 12.

What I tried to solve this?

• Re-generate my certificates in the Apple Developer page.
• Editing my scheme to 'Debug Configuration' to 'Release' and checking and unchecking 'Debug executable'.
• Restart my Mac and restart the iPad
• Enabling and disabling 'Wait for executable to be launched'

And also, each solution of this thread: Xcode 9 error: "iPhone has denied the launch request"

And after try each one of those alternatives, the problem persist only with the devices WITH iOS 12.

Someone has an idea about how can solve this?

UPDATE I debugged my app, and this is whole the log:

Answer 1

I also suffered the same issues with iOS 12 and Xcode 10 yesterday. I solved it by setting "Always Embed Swift Standard Libraries" to Yes.

In Xcode, choose Target → Build Settings → Always Embed Swift Standard Libraries, and set the value to Yes.
