Since yesterday I've been getting the following error when trying run an app on my device: "A valid provisioning profile for this executable was not found.". This is after updating to Xcode 10. Building with Xcode 9 last week worked without issues.
I've checked the other discussions about the error, but none of the solutions works.
The issue isn't limited to a single project I've been working on as it affects several all from different signing teams.
So far I've tried the following:
Cleaning derived data
Uninstalling Xcode, deleting any preferences and files related to it.
Installing Xcode on a completely different Mac
Testing with different devices
Disabling device in developer profile and letting Xcode enable it again.
Deleting all certificates in the developer portal and recreating them
Unchecking and rechecking "Automatically manage signing"
Trashing the provisioning profile and letting Xcode recreate it
Creating a manual provisioning profile in the developer profile
The project contains no tests so there can't be a problem with wrong signing settings on that target. Date / Time is set to Automatic
One thing of note is that no Provisioning Profiles are listed here, except for the manual one I created: https://developer.apple.com/account/ios/profile/
I'd expect the xcode generated one to show up as they do for all other clients.
Below are the signing settings I'm currently using
I've yet to try downgrading Xcode to an older version to see if that works. Other than that I have no idea of what to try next.
I was struggling with this today, it was super frustrating. For now, just go into "File/Project Settings and then Select "Legacy Build System" from the dropdown.
