Xcode 7.1 while archiving app, hangs at \'Copying Swift standard libraries\'.
Any idea why?
Log out, log back in. Faster than restarting your mac!
If you are not planning to release on AppStore and only creating an ad hoc build for testing, then do the following:
In Xcode 7, Goto Product -> Scheme -> Edit Scheme From the left menu select "Archive" and Select "Distribution" from the "Build Configuration" drop down.
For me it was the Wi-Fi connection. It seems that Xcode 8 tries to go out to the Internet for signing frameworks / apps and if that connection is really slow it takes a lot of time (for me up to 15 minutes). As soon as I changed the Wi-Fi network it built and ran in under 5 seconds.
For anyone else facing the same issue. After trying and failing everything else, it was fixed by restarting the mac :D
