Select “View” -> “Show Expired Certificates” in Keychain app.

I was getting this same starting on the 14th of Feb. I found out it’s because of a expired certificate on your mac.

  • So go into your keychain access
  • Click on Login Keychains and click down on Category Certificates,
  • then click on the view tab up top and check box “show expired certificates”
  • Then delete the expired ones with a red x.
  • Go into System and delete the expired certificates there as well.

Then you can build to devices and do a regular mac build again! It’s something to do with the
expired Apple Worldwide Developer Relations Certificate Authority certificates that expired on Feb 14th.

And if you don’t have the new ones that go until 2023 you can download them here
https://developer.apple.com/certificationauthority/AppleWWDRCA.cer

*And don’t forget to check the full rebuild box in the packaging settings to get all your levels in the build.

thanks mate - will give this a run!

I got hit with this too, lost a day trying to figure out why our dev certificates were invalid. Thanks Apple!!

ok m facing this issues too. Anyone facing iOS provisioning issues?? - iOS Development - Unreal Engine Forums
But haven’t quite got across.

Check to make sure your Bundle Identifier is the same as what you put on the Apple Dev page
