SpecGen

SpecGen is a command line tool for generating podspec files from frameworks, so they can be used in a CocoaPods setup.

• 🔥 Generates .podspec files from .framework files
• 🔥 Carthage compatibility, so the generated .podspec files contain the version specified in the Carfile.resolved (effectively delegating to Carthage the dependency resolution)
• 🔥 Use CocoaPods and Carthage together, allowing pods to depend on frameworks installed by Carthage
• 🔥 Massively reduce build times by substituting source code pods with their .framework

Installing

Mint

mint install acecilia/specgen

Make

git clone https://github.com/acecilia/specgen.git
cd SpecGen
make

Usage (with Carthage)

1. Tell SpecGen which .podspec files to generate by customizing your Cartfile:

   github "SwiftKickMobile/SwiftMessages" == 5.0.1
   
   # specgen:start
   github "hackiftekhar/IQKeyboardManager" == 6.2 # specgen:frameworks IQKeyboardManager IQKeyboardManagerSwift
   github "madebybowtie/FlagKit" == 2.2
   

2. Generate the .podspec files:

   specgen bootstrap

3. Integrate the .podspec files in your Podfile:

load '<path_to_frameworks>/Podfile' # <==============
target 'MyApp' do
    autogenerated_pods # <==============
    pod 'Alamofire', '~> 3.0'
end

Advanced usage

Generate .podspec files

If you are using Carthage (by default specgen looks for the frameworks under Carthage/Build/iOS), simply run:

specgen bootstrap

If not, you have to specify the path containing the frameworks:

specgen bootstrap --frameworksPath <path_to_frameworks>

This will generate the necessary .podspec files next to the frameworks.

To see all the possible options, run:

specgen --help

Integrate the .podspec files in your Podfile

You have two options:

• Using the autogenerated Podfile:

  load '<path_to_frameworks>/Podfile' # <==============
  target 'MyApp' do
      autogenerated_pods # <==============
      pod 'Alamofire', '~> 3.0'
  end

• Not using the autogenerated Podfile: point each pod to the local path containing the .podspec file:

  target 'MyApp' do
      pod 'FlagKit', :path => '<path_to_frameworks>'
      pod 'IQKeyboardManager', :path => '<path_to_frameworks>'
      pod 'IQKeyboardManagerSwift', :path => '<path_to_frameworks>'
      pod 'NVActivityIndicatorView', :path => '<path_to_frameworks>'
      pod 'NVActivityIndicatorViewAppExtension', :path => '<path_to_frameworks>'
      pod 'Result', :path => '<path_to_frameworks>'
      pod 'SideMenu', :path => '<path_to_frameworks>'
      pod 'SnapKit', :path => '<path_to_frameworks>'
      pod 'SwiftMessages', :path => '<path_to_frameworks>'
      pod 'Alamofire', '~> 3.0'
  end

Use a Cartfile to customize which .podspec files to generate:

it is possible to add comments to a Cartfile in order to specify which of the frameworks requires a .podspec. Take the following Cartfile as an example:

github "SwiftKickMobile/SwiftMessages" == 5.0.1

# specgen:start
github "hackiftekhar/IQKeyboardManager" == 6.2 # specgen:frameworks IQKeyboardManager IQKeyboardManagerSwift
github "madebybowtie/FlagKit" == 2.2

SpecGen will generate .podspec files for three frameworks:

• IQKeyboardManager, with version 6.2
• IQKeyboardManagerSwift, with version 6.2
• FlagKit, with version 2.2

This allows to add some frameworks in your project by following the official Carthage method, and some others through CocoaPods, using the .podspec files generated by SpecGen.
