View source for Xcode Project

== Project-related files outside the .xcodeproj file ==

When you create a project called "MyProject", Xcode will create a directory (a regular one, which looks and acts like a folder to Finder, not a special kind of directory like the .xcodeproj file which acts like a single file) called ''MyProject'' beneath whatever location you selected in which the project should be placed (your desktop, your user home directory, some subdirectory of it, etc.). All files related to the project get placed within this directory.

Within this directory is found these items (they may vary depending on the version of Xcode and the target operating system of the app, as well as other characteristics of the project):

* Another subdirectory also  named ''MyProject''. This has the rather redundant path ''MyProject/MyProject''. All the "content" files of your project such as program sources end up placed within this. Under this directory are:
** '''.m''' and '''.h''' source files of [[Objective-C]]
** '''.swift''' source files of [[Swift]]
** Other resources used in the project such as graphic files, if the developer put them into the project directory instead of just referencing them elsewhere.
** ''MyProject'''''-info.plist''', a file with some overall settings of the project/app, expressed in [[Property List/XML]] format.
** ''MyProject'''''-Prefix.pch''', a [[precompiled header file]] with global headers to be prefixed to the source files
** Language-specific '''.lproj''' subdirectories (e.g., ''en.lproj'' for English); there may be several if the app is being localized for multiple languages. Under this directory are:
*** [[Strings File]]s ('''.strings''') giving localized strings to be used in the program for a particular language (e.g., ''Localizable.strings'', ''InfoPlist.strings''). These are in the [[UTF-8]] text-based format of strings files here, but get converted to other formats ([[UTF-16]] or binary) to be placed within the app file when a project is built.
*** [[Nib file]]s, [[Xib file]]s, or [[Storyboard file]]s, depending on the Xcode version and target OS. These set up user interfaces.
*** '''Credits.rtf''': this [[RTF]] (Rich Text Format) file gives program credits to be shown within the help menu of the app.
* ''MyProject''''' Tests''': Another directory parallel to the one with all the project source files but within the top-level directory of the project; it contains files of similar types to the project sources, but instead of containing the app sources themselves, it contains sources for automated tests to be run on the app.
* ''MyProject'''''.xcodeproj''': Finally you get to the Xcode project file itself, actually a subdirectory. Its contents are described in the next section.
