Editing Xcode (section)

== Version history ==

=== 1.x series ===
Xcode 1.0 was released in fall 2003. Xcode 1.0 was based on [[Project Builder]], but had an updated [[user interface]] (UI), ZeroLink, Fix & Continue, distributed build support, and Code Sense indexing.

The next significant release, Xcode 1.5, had better code completion and an improved debugger.

=== 2.x series ===
Xcode 2.0 was released with [[Mac OS X v10.4]] "Tiger". It included the [[Quartz Composer]] visual programming language, better Code Sense indexing for Java, and [[Apache Ant|Ant]] support. It also included the Apple Reference Library tool, which allows searching and reading online documentation from Apple's website and documentation installed on a local computer.

Xcode 2.1 could create [[universal binary]] files. It supported shared [[precompiled header]]s, unit testing targets, conditional breakpoints, and watchpoints. It also had better dependency analysis.

The final version of Xcode for [[Mac OS X v10.4]] was 2.5.

=== 3.x series ===
Xcode 3.0 was released with [[Mac OS X v10.5]] "Leopard". Notable changes since 2.1 include<ref>{{cite web|url=https://www.apple.com/macosx/features/300.html#xcode3|title=Apple - Mac OS X Leopard - Features - 300+ New Features|archive-url=https://web.archive.org/web/20071016170507/http://www.apple.com/macosx/features/300.html#xcode3|archive-date=October 16, 2007}}</ref> the [[DTrace]] debugging tool (now named [[Instruments (application)|Instruments]]), refactoring support, context-sensitive documentation, and [[Objective-C]] 2.0 with [[Garbage collection (computer science)|garbage collection]].  It also supports Project Snapshots, which provide a basic form of version control; Message Bubbles, which show build errors debug values alongside code; and building four-architecture fat binaries (32 and 64-bit Intel and PowerPC).

Xcode 3.1 was an update release of the developer tools for Mac OS X, and was the same version included with the iPhone SDK. It could target non-Mac OS X platforms, including iPhone OS 2.0. It included the GCC 4.2 and [[LLVM]] GCC 4.2 compilers. Another new feature since Xcode 3.0 is that Xcode's SCM support now includes Subversion 1.5.

Xcode 3.2 was released with [[Mac OS X v10.6]] "Snow Leopard" and installs on no earlier version of OS X.  It supports [[static program analysis]], among other features. It also drops official support for targeting versions earlier than iPhone OS 3.0. But it is still possible to target older versions, and the simulator supports iPhone OS 2.0 through 3.1. Also, [[Java (software platform)|Java]] support is "exiled" in 3.2 to the organizer.<ref>{{cite web|url=https://developer.apple.com/library/mac/documentation/Java/Conceptual/Java14Development/02-JavaDevTools/JavaDevTools.html#//apple_ref/doc/uid/TP40001884-SW1|title=Apple Developer Tools for Java|publisher=[[Apple Inc.|Apple]]|access-date=February 8, 2011}}</ref>

Xcode 3.2.6 is the last version that can be downloaded for free for users of Mac OS X Snow Leopard (though it’s not the last version that supports Snow Leopard; 4.2 is). Downloading Xcode 3.2.6 requires a free registration at Apple's developer site.

Xcode 4.0 drops support for many older systems, including all PowerPC development and [[software development kit]]s (SDKs) for Mac OS X 10.4 and 10.5, and all iOS SDKs older than 4.3.  The deployment target can still be set to produce binaries for those older platforms, but for Mac OS platforms, one is then limited to creating [[x86]] and [[x86-64]] binaries. Later, Xcode was free to the general public.
