@maczydeco you get one clap
isaiah@maczydeco documentation probably needs work
Ben Syverson@maczydeco I hear there’s Cocoa on the level above
Ayo^@maczydeco I wonder if you get Toll-Free Bridging
GreenSkyOverMe (Monika)@maczydeco What’s the joke?
@GreenSkyOverMe Foundation is the Objective-C library providing basic types and functionality. Types and constants in this and other system frameworks are prefixed “NS” (eg. NSArray, NSString, NSFileCoordinatorReadingWithoutChanges), because Objective-C doesn’t have namespaces. NS is short for NeXTSTEP, the OS for which they were developed.
@maczydeco Thanks a lot!
Sharkie@maczydeco You get so much for free!
George Yang@maczydeco A joke that only Mac developers understand.
