@mjtsai Does anybody outside of Apple’s Xcode distribute .their apps in xip format? I never saw it before Xcode 8.
Michael Tsai ‏@mjtsai Jul 21

@jacobgorban Not that I’m aware of, but perhaps that will change.
Spencer MacDonald ‏@ObjColumnist Jul 21

@mjtsai @jacobgorban Xcode 8 was the first time I saw it. The only difference is it is signed? Most apps aren’t even signed!
Michael Tsai ‏@mjtsai Jul 21

@ObjColumnist @jacobgorban Difference compared with what?
Spencer MacDonald ‏@ObjColumnist Jul 21

@mjtsai @jacobgorban just a standard zip
Michael Tsai ‏@mjtsai Jul 21

@ObjColumnist @jacobgorban Functionally, signing is the main difference with .zip. Technically, it’s a different format based on .xar.
Jacob Gorban ‏@jacobgorban Jul 21 Winnipeg, Manitoba

@mjtsai @ObjColumnist But if the application inside the .zip is signed, why also sign the package it’s in (.xip)? I don’t see the value.

@mjtsai @jacobgorban @ObjColumnist Do you know if .xip files are subject to Gatekeeper Path Randomization?
