Our iOS Programming and Cocoa Programming for Mac OS X guides are written for experienced programmers with knowledge of C and object-oriented programming, and have been updated for Swift. They are separate books, however. If you want to develop only iOS apps, there is no need to read Cocoa Programming.

Third parties have added support for,,,,,. Minecraft servers for mcpe. Xcode can build files containing code for multiple architectures with the executable format.
These are called files, which allow software to run on both and -based () and that can include both and code for both architectures. Using the, Xcode can also be used to compile and debug applications for that run on processors. Xcode includes the GUI tool, which runs atop a dynamic tracing framework,, created by and released as part of. Composition [ ] The main application of the suite is the (IDE), also named Xcode. The Xcode suite includes most of Apple's developer documentation, and built-in, an application used to construct. Up to Xcode 4.1, the Xcode suite included a modified version of the. In Xcode 3.1 up to Xcode 4.6.3, it included the LLVM-GCC compiler, with front ends from the and a code generator based on.
In Xcode 3.2 and later, it included the C/C++/Objective-C compiler, with newly-written front ends and a code generator based on LLVM, and the Clang. Starting with Xcode 4.2, the Clang compiler became the default compiler, Starting with Xcode 5.0, Clang was the only compiler provided. Up to Xcode 4.6.3, the Xcode suite used the (GDB) as the for the IDE's. Starting with Xcode 4.3, the was also provided; starting with Xcode 4.5 LLDB replaced GDB as the default back-end for the IDE's debugger. Starting with Xcode 5.0, GDB was no longer supplied.
Removed features [ ] Formerly, Xcode supported distributing a product build process over multiple systems. One technology involved was named Shared Workgroup Build, which used the to automatically discover systems providing compiler services, and a modified version of the free software product to facilitate the distribution of workloads. Earlier versions of Xcode provided a system named Dedicated Network Builds. These features are absent in the supported versions of Xcode.
Xcode also includes Apple's tools and frameworks for building Java web applications and web services (formerly sold as a separate product). As of Xcode 3.0, Apple dropped WebObjects development inside Xcode; WOLips should be used instead. Xcode 3 still includes the WebObjects frameworks. Version history [ ] 1.x series [ ] Xcode 1.0 was released in fall 2003. Xcode 1.0 was based on, but had an updated (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 'Tiger'.
It included the visual programming language, better Code Sense indexing for Java, and 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 files.
It supported shared, unit testing targets, conditional breakpoints, and watchpoints. It also had better dependency analysis. The final version of Xcode for was 2.5.
3.x series [ ] Xcode 3.0 was released with 'Leopard'. Notable changes since 2.1 include the debugging tool (now named ), refactoring support, context-sensitive documentation, and 2.0 with. 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 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 'Snow Leopard' and installs on no earlier version of OS X. It supports, 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, support is 'exiled' in 3.2 to the organizer. Xcode 3.2.6 is the last version that can be downloaded for free for users of.
Downloading it requires a free registration at Apple's developer site. 4.x series [ ] In June 2010, at the version 4 of Xcode was announced during the Developer Tools State of the Union address. Version 4 of the developer tools consolidates the Xcode editing tools and Interface Builder into one application, among other enhancements. Apple released the final version of Xcode 4.0 on March 9, 2011. The software was made available for free to all registered members of the $99 per year Mac Developer program and the $99 per year iOS Developer program.
