Installation

• In the Terminal, go to where you want to download SwiftShell.

• Run

    git clone https://github.com/kareman/SwiftShell.git 
    cd SwiftShell
  

• Copy/link Div/swiftshell to your bin folder or anywhere in your PATH.

• To install the framework, either:

  • run xcodebuild install from the project's root folder. This will install the SwiftShell framework in ~/Library/Frameworks.
  • or run xcodebuild and copy the resulting framework from the build folder to your library folder of choice. If that is not "~/Library/Frameworks", "/Library/Frameworks" or a folder mentioned in the $DYLD_FRAMEWORK_PATH environment variable then you need to add your folder to $DYLD_FRAMEWORK_PATH.
