A valid provisioning profile for this executable was not found error Xcode 9

Question

I have an iPhone on which until last evening was able to run an app without issue , my iphone is added to the developer portal and signing is set to auto in Xcode 9, and it was running fine. Since last morning I have started receiving error

A valid provisioning profile for this executable was not found

I can see the device is on developer portal , also I am able to install the app on other phone from Xcode 9 just fine. So clearly this is not developer portal related issue.

I have restarted / fully restarted iPhone a few times and also quite Xcode 9 as well, but doesn't seems to work.

How can this be solved ?

Answer 1

Never mind this was solved as follows,

Removed the derived data folder and removed the device from Xcode , restarted Xcode, and connected iPhone again , this time it reindexed the device and all worked just fine.

Answer 2

Fixed this issue by going to developer.apple.com/account > Certificates, IDs & Profiles > Provisioning Profile > Development, create or download an existing valid provisioning profile and double-click it. It should add the provisioning profile to the device you're using.
