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](guides.cocoapods.org/terminal/commands.html#pod_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 |spec|
  spec.name         = 'Reachability'
  spec.version      = '3.1.0'
  spec.license      = { :type => 'BSD' }
  spec.homepage     = 'https://github.com/tonymillion/Reachability'
  spec.authors      = { 'Tony Million' => '[email protected]' }
  spec.summary      = 'ARC and GCD Compatible Reachability Class for iOS and OS X.'
  spec.source       = { :git => 'https://github.com/tonymillion/Reachability.git', :tag => 'v3.1.0' }
  spec.source_files = 'Reachability.{h,m}'
  spec.framework    = 'SystemConfiguration'
end

Or it can be quite detailed:

Pod::Spec.new do |spec|
  spec.name         = 'Reachability'
  spec.version      = '3.1.0'
  spec.license      = { :type => 'BSD' }
  spec.homepage     = 'https://github.com/tonymillion/Reachability'
  spec.authors      = { 'Tony Million' => '[email protected]' }
  spec.summary      = 'ARC and GCD Compatible Reachability Class for iOS and OS X.'
  spec.source       = { :git => 'https://github.com/tonymillion/Reachability.git', :tag => 'v3.1.0' }
  spec.module_name  = 'Rich'

  spec.ios.deployment_target  = '9.0'
  spec.osx.deployment_target  = '10.10'

  spec.source_files       = 'Reachability/common/*.swift'
  spec.ios.source_files   = 'Reachability/ios/*.swift', 'Reachability/extensions/*.swift'
  spec.osx.source_files   = 'Reachability/osx/*.swift'

  spec.framework      = 'SystemConfiguration'
  spec.ios.framework  = 'UIKit'
  spec.osx.framework  = 'AppKit'

  spec.dependency 'SomeOtherPod'
end

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 =

Class Attribute Summary collapse

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

Platform A specification should indicate the platform 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

Build settings In this group are listed the attributes related to the configuration of the build environment that should be used to build the library. If not defined in a subspec the attributes of this group inherit the value of the parent. collapse

File patterns Podspecs should be located at the **root** of the repository, and paths to files should be specified **relative** to the root of the repository as well. File patterns do not support traversing the parent directory ( `..` ). File patterns 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). "JSONKit.?" #=> ["JSONKit.h", "JSONKit.m"] "*.[a-z][a-z]" #=> ["CHANGELOG.md", "README.md"] "*.[^m]*" #=> ["JSONKit.h"] "*.{h,m}" #=> ["JSONKit.h", "JSONKit.m"] "*" #=> ["CHANGELOG.md", "JSONKit.h", "JSONKit.m", "README.md"] collapse

Subspecs A library can specify a dependency on either another library, a subspec of another library, or a subspec of itself. collapse

Multi-Platform support A specification can store values which are specific to only one platform. --- For example one might want to store resources which are specific to only iOS projects. spec.resources = 'Resources/**/*.png' spec.ios.resources = 'Resources_ios/**/*.png' collapse

Instance Method Details

#authors=(authors) ⇒ Object

The name and email addresses of the library maintainers, not the Podspec maintainer.

Examples:


spec.author = 'Darth Vader'

spec.authors = 'Darth Vader', 'Wookiee'

spec.authors = { 'Darth Vader' => '[email protected]',
                 'Wookiee'     => '[email protected]' }

Parameters:

  • authors (String, Hash{String=>String}) —

#cocoapods_version=(cocoapods_version) ⇒ Object

The version of CocoaPods that the specification supports.

Examples:


spec.cocoapods_version = '>= 0.36'

Parameters:

  • cocoapods_version (String) —

    the CocoaPods version that the specification supports. CocoaPods follows [semantic versioning](semver.org).

#compiler_flags=(flags) ⇒ Object

A list of flags which should be passed to the compiler.

Examples:


spec.compiler_flags = '-DOS_OBJECT_USE_OBJC=0', '-Wno-format'

Parameters:

  • flags (String, Array<String>) —

    A list of flags.

#default_subspecs=(subspec_array) ⇒ Object

An array of subspecs names 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).

Examples:


spec.default_subspec = 'Core'
spec.default_subspecs = 'Core', 'UI'

Parameters:

  • subspec_names (Array<String>) —

    An array of subspec names that should be inherited as dependency.

#dependency(*args) ⇒ Object

Any dependency on other Pods or to a ‘sub-specification’.

Dependencies can specify versions requirements. The use of the optimistic version indicator ‘~>` is recommended because it provides good control over the version without being too restrictive. For example, `~> 1.0.1` is equivalent to `>= 1.0.1` combined with `< 1.1`. Similarly, `~> 1.0` will match `1.0`, `1.0.1`, `1.1`, but will not upgrade to `2.0`.

Pods with overly restrictive dependencies limit their compatibility with other Pods.

Examples:

spec.dependency 'AFNetworking', '~> 1.0'
spec.dependency 'RestKit/CoreData', '~> 0.20.0'
spec.ios.dependency 'MBProgressHUD', '~> 0.5'

#prepare_command=(command) ⇒ Object

A bash script that will be executed after the Pod is downloaded. This command can be used to create, delete and modify any file downloaded and will be ran before any paths for other file attributes of the specification are collected.

This command is executed before the Pod is cleaned and before the Pods project is created. The working directory is the root of the Pod.

If the pod is installed with the ‘:path` option this command will not be executed.

Examples:


spec.prepare_command = 'ruby build_files.rb'

spec.prepare_command = <<-CMD
                        sed -i 's/MyNameSpacedHeader/Header/g' ./**/*.h
                        sed -i 's/MyNameOtherSpacedHeader/OtherHeader/g' ./**/*.h
                   CMD

Parameters:

  • command (String) —

    the prepare command of the pod.

root_attribute :prepare_command

#preserve_paths=(preserve_paths) ⇒ Object

Any file that should not be removed after being downloaded.

By default, CocoaPods removes all files that are not matched by any of the other file pattern.

Examples:


spec.preserve_path = 'IMPORTANT.txt'

spec.preserve_paths = 'Frameworks/*.framework'

Parameters:

  • preserve_paths (String, Array<String>) —

    the paths that should be not cleaned.

:file_patterns => true,
:singularize   => true

#private_header_files=(private_header_files) ⇒ Object

A list of file patterns that should be used to mark private headers.

These patterns are matched against the public headers (or all the headers if no public headers have been specified) to exclude those headers which should not be exposed to the user project and which should not be used to generate the documentation. When the library is built, these headers will appear in the build directory.

Header files that are not listed as neither public nor private will be treated as private, but in addition will not appear in the build directory at all.

Examples:


spec.private_header_files = 'Headers/Private/*.h'

Parameters:

#public_header_files=(public_header_files) ⇒ Object

A list of file patterns that should be used as public headers.

These are the headers that will be exposed to the user’s project and from which documentation will be generated. When the library is built, these headers will appear in the build directory. If no public headers are specified then all the headers in source_files are considered public.

Examples:


spec.public_header_files = 'Headers/Public/*.h'

Parameters:

  • public_header_files (String, Array<String>) —

    the public headers of the Pod.

#requires_arc=(flag) ⇒ Object

‘requires_arc` allows you to specify which source_files use ARC. This can either be the files which support ARC, or true to indicate all of the source_files use ARC.

Files which do not use ARC will have the ‘-fno-objc-arc` compiler flag.

The default value of this attribute is ‘true`.

Examples:


spec.requires_arc = false

spec.requires_arc = 'Classes/Arc'

spec.requires_arc = ['Classes/*ARC.m', 'Classes/ARC.mm']

Parameters:

  • flag (Bool, String, Array<String>) —

    whether the source files require ARC.

#resource_bundles=(*frameworks) ⇒ Object

This attribute allows to define the name and the file of the resource bundles which should be built for the Pod. They are specified as a hash where the keys represent the name of the bundles and the values the file patterns that they should include.

We strongly recommend library developers to adopt resource bundles as there can be name collisions using the resources attribute.

The names of the bundles should at least include the name of the Pod to minimise the chance of name collisions.

To provide different resources per platform namespaced bundles must be used.

Examples:


spec.ios.resource_bundle = { 'MapBox' => 'MapView/Map/Resources/*.png' }

spec.resource_bundles = {
    'MapBox' => ['MapView/Map/Resources/*.png'],
    'OtherResources' => ['MapView/Map/OtherResources/*.png']
  }

Parameters:

  • resource_bundles (Hash{String=>String}) —

    A hash where the keys are the names of the resource bundles and the values are their relative file patterns.

#resources=(resources) ⇒ Object

A list of resources that should be copied into the target bundle.

We strongly recommend library developers to adopt [resource bundles](guides.cocoapods.org/syntax/podspec.html#resource_bundles) as there can be name collisions using the resources attribute. Moreover, resources specified with this attribute are copied directly to the client target and therefore they are not optimised by Xcode.

Examples:


spec.resource = 'Resources/HockeySDK.bundle'

spec.resources = ['Images/*.png', 'Sounds/*']

Parameters:

  • resources (String, Array<String>) —

    The resources shipped with the Pod.

#screenshots=(screenshots) ⇒ Object

A list of URLs to images showcasing the Pod. Intended for UI oriented libraries. CocoaPods recommends the usage of the ‘gif` format.

Examples:


spec.screenshot  = 'http://dl.dropbox.com/u/378729/MBProgressHUD/1.png'

spec.screenshots = [ 'http://dl.dropbox.com/u/378729/MBProgressHUD/1.png',
                     'http://dl.dropbox.com/u/378729/MBProgressHUD/2.png' ]

#social_media_url=(social_media_url) ⇒ Object

The URL for the social media contact of the Pod, CocoaPods web services can use this.

For example, the @CocoaPodsFeed notifications will include the Twitter handle (shortening the description) if the URL is relative to Twitter. This does not necessarily have to be a Twitter URL, but only those are included in the Twitter @CocoaPodsFeed notifications.

Examples:


spec.social_media_url = 'https://twitter.com/cocoapods'

spec.social_media_url = 'https://groups.google.com/forum/#!forum/cocoapods'

Parameters:

  • social_media_url (String) —

    the social media URL.

#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 as 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.

Examples:

Subspecs with different source files.


subspec 'Twitter' do |sp|
  sp.source_files = 'Classes/Twitter'
end

subspec 'Pinboard' do |sp|
  sp.source_files = 'Classes/Pinboard'
end

Subspecs referencing dependencies to other subspecs.


Pod::Spec.new do |s|
  s.name = 'RestKit'

  s.subspec 'Core' do |cs|
    cs.dependency 'RestKit/ObjectMapping'
    cs.dependency 'RestKit/Network'
    cs.dependency 'RestKit/CoreData'
  end

  s.subspec 'ObjectMapping' do |os|
  end
end

Nested subspecs.


Pod::Spec.new do |s|
  s.name = 'Root'

  s.subspec 'Level_1' do |sp|
    sp.subspec 'Level_2' do |ssp|
    end
  end

end

#summary=(summary) ⇒ Object

A short (maximum 140 characters) description of the Pod.

The description should be short, yet informative. It represents the tag line of the Pod and there is no need to specify that a Pod is a library (they always are).

The summary is expected to be properly capitalised and containing the correct punctuation.

Examples:


spec.summary = 'Computes the meaning of life.'

Parameters:

  • summary (String) —

    A short description of the Pod.

Examples:


Pod::Spec.new do |spec|
  spec.name = 'NSAttributedString+CCLFormat'

  spec.test_spec do |test_spec|
    test_spec.source_files = 'NSAttributedString+CCLFormatTests.m'

end

#user_target_xcconfig=(value) ⇒ Object

Specifies flags to add to the final aggregate target xcconfig file, which propagates to non-overridden and inheriting build settings to the integrated user targets.

This attribute is __not recommended__ as Pods should not pollute the build settings of the user project and this can cause conflicts.

Multiple definitions for build settings that take multiple values will be merged. The user is warned on conflicting definitions for custom build settings and build settings that take only one value.

Typically clang compiler flags or precompiler macro definitions go in here if they are required when importing the pod in the user target. Note that, this influences not only the compiler view of the public interface of your pod, but also all other integrated pods alongside to yours. You should always prefer [‘pod_target_xcconfig`]( guides.cocoapods.org/syntax/podspec.html#pod_target_xcconfig), which can contain the same settings, but only influence the toolchain when compiling your pod target.

Examples:


spec.user_target_xcconfig = { 'MY_SUBSPEC' => 'YES' }

Parameters:

  • value (Hash{String => String}) —

    Key-value pairs representing build settings.
