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 command.


The specification DSL provides great flexibility and dynamism. Moreover, the DSL adopts the 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.swift_version = '4.0'

  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.

attribute :compiler_flags,
:container   => Array,

:inherited => true

#default_subspecs=(subspec_array) ⇒ Object

An array of subspecs names that should be used as preferred dependency. If not specified, a specification requires all of its subspecs as dependencies.

You may use the value :none to specify that none of the subspecs are required to compile this pod and that all subspecs are optional.


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'

spec.default_subspecs = :none

Parameters:

  • subspec_names (Array<String>, String, Symbol)

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

# File 'lib/cocoapods-core/specification/dsl.rb', line 1826

root_attribute :default_subspecs,
:container => Array,
:types => [Array, String, Symbol],
:singularize => true

#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 'AFNetworking', '~> 1.0', :configurations => ['Debug']
spec.dependency 'AFNetworking', '~> 1.0', :configurations => :debug
spec.dependency 'RestKit/CoreData', '~> 0.20.0'
spec.ios.dependency 'MBProgressHUD', '~> 0.5'

spec.module_map = false

Parameters:

  • module_map (String, Bool)

    the path to the module map file that should be used or whether to disable module_map generation.

#on_demand_resources=(on_demand_resources) ⇒ Object

Note:

A hash of on demand resources that should be copied into the target bundle. Resources specified here will automatically become part of the resources build phase of the target this pod is integrated into.

If no category is specified then :download_on_demand is used as the default.

Tags specified by pods are always managed by CocoaPods. If a tag is renamed, changed or deleted then CocoaPods will update the tag within the targets the pod was integrated into. It is highly recommended not to share the same tags for your project as the ones used by the pods your project consumes.

Examples:


s.on_demand_resources = {
  'Tag1' => 'file1.png'
}

s.on_demand_resources = {
  'Tag1' => ['file1.png', 'file2.png']
}

s.on_demand_resources = {
  'Tag1' => { :paths => ['file1.png', 'file2.png'], :category => :download_on_demand }
}

s.on_demand_resources = {
  'Tag1' => { :paths => ['file1.png', 'file2.png'], :category => :initial_install }
}

Parameters:

  • on_demand_resources (Hash{String=>String}, Hash{String=>Array<String>}, Hash{String=>Hash})

    The on demand resources shipped with the Pod.

#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 project or 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:

  • private_header_files (String, Array<String>)

    the private headers of the Pod.

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


These patterns are matched against the source files to include 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.

#resource_bundles=(*resource_bundles) ⇒ 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.

For building the Pod as a static library, 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'],
    'MapBoxOtherResources' => ['MapView/Map/OtherResources/*.png']
  }

Parameters:

  • resource_bundles (Hash{String=>String}, Hash{String=>Array<String>})

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

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

For building the Pod as a static library, we strongly recommend library developers to adopt 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/*']

#script_phases=(*script_phases) ⇒ Object

This attribute allows to define a script phase to execute as part of compilation of the Pod. Unlike a prepare command, script phases execute as part of xcodebuild they can also utilize all environment variables that are set during compilation.

A Pod can provide multiple script phases to execute and they will be added in the order they were declared and after taking into consideration their execution position setting.

Note In order to provide visibility and awareness of the contents of all script phases, a warning will be presented to the user upon installing your pod if it includes any script phases.

Examples:


spec.script_phase = { :name => 'Hello World', :script => 'echo "Hello World"' }

spec.script_phase = { :name => 'Hello World', :script => 'echo "Hello World"', :execution_position => :before_compile }

spec.script_phase = { :name => 'Hello World', :script => 'puts "Hello World"', :shell_path => '/usr/bin/ruby' }

spec.script_phase = { :name => 'Hello World', :script => 'echo "Hello World"',
  :input_files => ['/path/to/input_file.txt'], :output_files => ['/path/to/output_file.txt']
}

#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

#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.

#swift_versions=(version) ⇒ Object

The versions of Swift that the specification supports. A version of '4' will be treated as '4.0' by CocoaPods and not '4.1' or '4.2'.

Note The Swift compiler mostly accepts major versions and sometimes will honor minor versions. While CocoaPods allows specifying a minor or patch version it might not be honored fully by the Swift compiler.

Examples:


spec.swift_versions = ['3.0']

spec.swift_versions = ['3.0', '4.0', '4.2']

spec.swift_version = '3.0'

spec.swift_version = '3.0', '4.0'

Parameters:

#test_spec(name = 'Tests', &block) ⇒ Object

Represents a test specification for the library. Here you can place all your tests for your podspec along with the test dependencies.


Examples:


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

  spec.test_spec do |test_spec|
    test_spec.source_files = 'NSAttributedString+CCLFormatTests.m'
    test_spec.dependency 'Expecta'
  end
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, 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.

#vendored_frameworks=(*frameworks) ⇒ Object

The paths of the framework bundles that come shipped with the Pod. Supports both .framework and .xcframework bundles. The frameworks will be made available to the Pod and to the consumers of the pod.

Examples:


spec.ios.vendored_frameworks = 'Frameworks/MyFramework.framework'

spec.vendored_frameworks = 'MyFramework.framework', 'TheirFramework.xcframework'

Parameters:

  • vendored_frameworks (String, Array<String>)

    A list of framework bundles paths.
