Overview
A specification describes a version of Pod library. It includes details about where the source should be fetched from, what files to use, the build settings to apply, and other general metadata such as its name, version, and description.
A stub specification file can be generated by the [pod spec create](commands.html#tab_spec-create) command.
The specification DSL provides great flexibility and dynamism. Moreover, the DSL adopts the [convention over configuration](en.wikipedia.org/wiki/Convention_over_configuration) and thus it can be very simple:
Pod::Spec.new do |s|
s.name = 'Reachability'
s.version = '3.1.0'
s.license = { :type => 'BSD' }
s.homepage = 'https://github.com/tonymillion/Reachability'
s. = { 'Tony Million' => '[email protected]' }
s.summary = 'ARC and GCD Compatible Reachability Class for iOS and OS X. Drop in replacement for Apple Reachability.'
s.source = { :git => 'https://github.com/tonymillion/Reachability.git', :tag => 'v3.1.0' }
s.source_files = 'Reachability.{h,m}'
s.framework = 'SystemConfiguration'
s.requires_arc = true
end

Modules: AttributeSupport, Deprecations, RootAttributesAccessors Classes: Attribute, PlatformProxy
Root specification A ‘root’ specification stores the information about the specific version of a library. The attributes in this group can only be written to on the ‘root’ specification, **not** on the ‘sub-specifications’. --- The attributes listed in this group are the only one which are required by a podspec. The attributes of the other groups are offered to refine the podspec and follow a convention over configuration approach. A root specification can describe these attributes either directly of through ‘[sub-specifications](#subspec)’. collapse
- LICENSE_KEYS =
The keys accepted by the license attribute.
[ :type, :file, :text ].freeze
- SOURCE_KEYS =
The keys accepted by the hash of the source attribute.
{ :git => [:tag, :branch, :commit, :submodules], :svn => [:folder, :tag, :revision], :hg => [:revision], :http => nil, :local => nil }.freeze
Platform A specification should indicate the platforms and the correspondent deployment targets on which the library is supported. If not defined in a subspec the attributes of this group inherit the value of the parent. collapse
- PLATFORMS =
The names of the platforms supported by the specification class.
[:osx, :ios].freeze
File patterns These paths should be specified **relative** to the **root** of the source and may contain the following wildcard patterns: --- ### Pattern: * Matches any file. Can be restricted by other values in the glob. * `*` will match all files * `c*` will match all files beginning with `c` * `*c` will match all files ending with `c` * `*c*` will match all files that have `c` in them (including at the beginning or end) Equivalent to `/.*/x` in regexp. **Note** this will not match Unix-like hidden files (dotfiles). In order to include those in the match results, you must use something like `{*,.*}`. --- ### Pattern: ** Matches directories recursively. --- ### Pattern: ? Matches any one character. Equivalent to `/.{1}/` in regexp. --- ### Pattern: [set] Matches any one character in set. Behaves exactly like character sets in Regexp, including set negation (`[^a-z]`). --- ### Pattern: {p,q} Matches either literal `p` or literal `q`. Matching literals may be more than one character in length. More than two literals may be specified. Equivalent to pattern alternation in regexp. --- ### Pattern: \ Escapes the next meta-character. --- ### Examples Consider these to be evaluated in the source root of [JSONKit](https://github.com/johnezang/JSONKit).

#default_subspec=(subspec_name) ⇒ Object
The name of the subspec that should be used as preferred dependency. If not specified a specifications requires all its subspecs as dependencies.
A Pod should make available the full library by default. Users can fine tune their dependencies, and exclude unneeded subspecs, once their requirements are known. Therefore, this attribute is rarely needed. It is intended to be used to select a default if there are ‘sub-specifications’ which provide alternative incompatible implementations, or to exclude modules rarely needed (especially if they trigger dependencies on other libraries).

#dependency(*args) ⇒ Object
Any dependency on other Pods or to a ‘sub-specification’.
Dependencies can specify versions requirements. The use of the spermy indicator ‘~>` is recommended because it provides a good compromise between control on the version without being too restrictive.
Pods with too restrictive dependencies, limit their compatibility with other Pods.

This is a convenience method which gets called after all pods have been downloaded, installed, and the Xcode project and related files have been generated. Note that this hook is called for each Pods library and only for installations where the Pod is installed.

#subspec(name, &block) ⇒ Object
Represents specification for a module of the library.
Subspecs participate on a dual hierarchy.
On one side, a specification automatically inherits as a dependency all it children ‘sub-specifications’ (unless a default subspec is specified).
On the other side, a ‘sub-specification’ inherits the value of the attributes of the parents so common values for attributes can be specified in the ancestors.
Although it sounds complicated in practice it means that subspecs in general do what you would expect:
pod 'ShareKit', '2.0'
Installs ShareKit with all the sharers like ‘ShareKit/Evernote`, `ShareKit/Facebook`, etc, as they are defined a subspecs.
pod 'ShareKit/Twitter', '2.0'
pod 'ShareKit/Pinboard', '2.0'
Installs ShareKit with only the source files for ‘ShareKit/Twitter`, `ShareKit/Pinboard`. Note that, in this case, the ‘sub-specifications’ to compile need the source files, the dependencies, and the other attributes defined by the root specification. CocoaPods is smart enough to handle any issues arising from duplicate attributes.
