Why are the installed Xcodes so huge?

[neonichu]

$ du -shc Xcode*
5.9G    Xcode-6.2.app
5.9G    Xcode-6.3.app

but App Store versions are ~2.5GB - I guess using cp -R is the correct way to copy stuff over and symlinks, etc. are retained by it. Maybe hard links or something else that cp destroys?

Using ditto instead of cp helps:

$ du -shc Xcode*
3.9G    Xcode-6.2.app

This is consistent with the size inside the DMG:

Volumes boris$ du -sch Xcode/
3.9G    Xcode/

Still begs the question why it is bigger than the App Store download.

Shipped using ditto in ee76566

OK, the rest of the difference in sizes seems to be attributable to differences in stripped symbols:

+ cp /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/Frameworks/CoreGraphics.framework/Resources/libCGCorePDF.dylib app-store.dylib
+ cp /Applications/Xcode-6.3.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/Frameworks/CoreGraphics.framework/Resources/libCGCorePDF.dylib dmg.dylib
+ diff app-store.dylib dmg.dylib
Binary files app-store.dylib and dmg.dylib differ
+ strip -S -X -x -c app-store.dylib dmg.dylib
+ diff app-store.dylib dmg.dylib

Don't really want to strip those symbols manually, so I guess a 📡 is in order.

There's nothing that can be done apart from that right now.
