this is driving me insane. I updated my device to IOS 12, and my xcode to v10. when I try to test it, it gives me the error stated in the heading.
then I inserted another device that uses ios 11 still, and in that device it launches with no problems.

please help guys. I have already tried deleting the everything from provisional Profiles and downloading manual profiles from xcode, it still gives me this error on ios 12.
I was having a similar issue, and it started when I updated my Xcode 9 to Xcode 10.
The same error:
A valid provisioning profile for this executable was not found.
However, it fails to build on a device that runs on iOS 11. I can build on a simulator or even archive and deploy to AppStore, no matter the iOS version I set on the deployment target.
I was reading the update notes for the Xcode 10 and noticed the following:
Build Performance
- New build system improves performance and is enabled by default for all projects
I was ready to downgrade my Xcode, but as a last resort I went to "File/Project Settings" and selected "Legacy Build System" from the dropdown. Now it builds with no issues. And yes, I'm using the Ionic3 framework too.
