Xcode can\'t download provisioning profiles, I m getting the error:
Error Downloading Profiles
Xcode encountered a problem downloadi
Looks like a bug with Xcode 10, and it was observed earlier with Xcode 8 as well as stated at Xcode Profiles Won't Download
As a workaround, you can try the following steps,
1) Visit developer.apple.com in Safari
2) Click Account and sign in
3) Click on Certificates, Identifiers, and Profiles
4) Navigate to the profile you're interested in and download it
5) Drag the downloaded profile onto Xcode's icon in the dock.
At this point, your profile will be installed on your Mac and usable within Xcode.
