@section Build
In Xcode perform the following steps to build the default configuration:
@itemize
@item open @file{macosx/HandBrake.xcodeproj}
@item select active configuration @b{standard}
@item select active target @b{HandBrake}
@item click @b{Build} or @b{Build and Go}
@end itemize
The first build (on an empty @file{build} directory) will take a bit of time. You may use the Build Results window to observe progress. The most time-consuming part of the build is when the external build system (essentially the @b{terminal} method) is triggered by Xcode and a substantial amount of log transcript ensues. Much of that transcript are warnings and errors that are part of the normal build process for 3rd-party contributed modules so in general you need not do anything. However, if Xcode itself reports the build failed, then you must take corrective action.
Unfortunately, due to limitations of Xcode we do not have hooks in place to offer finer-grained control over per-module make actions for the (external) build system. Thus, you will have to use @b{terminal} to accomplish those tasks. Just @command{cd} into the build directory which is associated with your active configuration and perform any necessary @command{make} commands. @b{Be careful not to issue commands from the terminal simultaneously with Xcode tasks} as that will confuse both Xcode and make and likely corrupt your build directory.
When you click @b{clean} in Xcode it will not perform an external build clean. Basically @b{HandBrakeCLI} and @b{HandBrake.app} are the only products which have full Xcode iterative development flexibility.
Each configuration uses a different @file{build} directory. This makes it possible to build each configuration and switch between them without losing their respective build state. The description of each configuration and the name convention for build directories are as follows:
@table @samp
@item standard
This configuration will build to the host native architecture. Build directory is @file{build.standard} .
The standard variant produces optimized code without debug information.
@item debug
This configuration will build to the host native architecture. Build directory is @file{build.standard} .
The debug variant produces unoptimized code with debug information.
@item standard.i386
This configuration is used to build for the i386 architecture. Build directory is @file{build.standard.i386} .
@item standard.x86_64
This configuration is used to build for the x86_64 architecture. Build directory is @file{build.standard.x86_64} .
@item standard.ppc
This configuration is used to build for the ppc architecture. Build directory is @file{build.standard.ppc} .
@item standard.ppc64
This configuration is used to build for the ppc64 architecture. Build directory is @file{build.standard.ppc64} .

@section External Targets
The following external targets appear in the Xcode project and perform @b{build} and @b{clean} actions.
@table @samp
@item external
Target maps to @command{make build} and @command{make clean} for everything Xcode products depend upon from the external build system.
@item libhb
Target maps to @command{make libhb.build} and @command{make libhb.clean}.
@item contrib
Target maps to @command{make contrib.build} and @command{make contrib.xclean}.
@end table
@c %**-------------------------------------------------------------------------
@anchor{xcode.userdefined}
@section User-Defined Settings
The following user defined settings are used in Xcode project for the external build system:
@table @samp
@item EXTERNAL_BUILD
Specifies the build location for each configuration.
It is highly recommended the locations always evaluate to a unique pathname when factoring the configuration name.
@item EXTERNAL_JOBS
Specifies the concurrency factor for the external build system when builds are launched from within Xcode.
This variable is meant to be customized by the developer for faster builds if the host supports it.
@item EXTERNAL_METHOD
This variable is used for internal/external build coordination and must always be @samp{xcode}.
@item EXTERNAL_PROJECT
Specifies the directory which is top of @value{HB.name} source tree.
@end table
