Xcode8 Provisioning profile expired on 2017-10-24 after changed the date of system

As titled, I changed the date of my computer system to 2038/1/1 for something else, and then I resume to 2016, however the profile in my Xcode 8 is expired on 2017/10/24 that is the system date is still 2038/1/1 as the photo shows below. The question is how can I solve it? Thank you.

Solution

Go to apple member center, check if that specific provision profile shows as valid or expired. I assume it will be valid, if so, delete that provision profile from your mac and re-download it from the member center. Inc case the provision profile is expired also in member center, then you will need to generate a new one...
