Project Builder
Template:Short description Script error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters".Template:Main other Project Builder was an integrated development environment (IDE) originally developed by NeXT for version 3 of the NeXTSTEP operating system by separating out the code editing parts of Interface Builder into its own application.[1]
After Apple Computer purchased NeXT and turned NeXTSTEP into the Mac OS X operating system, the NeXTSTEP version of Project Builder became ProjectBuilderWO (maintained only for WebObjects development). Apple created a new Project Builder from scratch for software development with the first version being introduced with Developer Preview 4 of Mac OS X.[2] This version of Project Builder, informally dubbed PBX.[3] was distributed with the first few versions of Mac OS X but with the release of Mac OS X v10.3 it was redesigned, reintegrated with Interface Builder and rebranded as Xcode.[4][5][6]
Before OS X, developers could use Macintosh Programmer's Workshop or CodeWarrior to develop Macintosh applications.
GNUstep's ProjectCenter IDE is a rough workalike of the original NextStep design; additional functionality is provided by ProjectManager, a 3rd-party GNUstep IDE meant for greater usability.
