Create a project

Clean up files and add main.swift

Add a framework

Run Carthagecarthage update --use-submodules

Set xcconfigs

Run bootstrap scriptobjc-build-scripts: standardize how Objective-C projects are

bootstrapped after cloning

New workspaceAdd all the projects into here

and Libraries

Copy frameworks in Build Phrases

Destination is frameworks

Runpath in Buld Settings for main target

Add components.plist for pkgbuild command<plist version="1.0"><array> <dict> <key>BundleIsVersionChecked</key> <false/> <key>BundleOverwriteAction</key> <string>upgrade</string> <key>ChildBundles</key> <array> <dict> <key>BundleOverwriteAction</key> <string></string> <key>RootRelativeBundlePath</key> <string>Library/Frameworks/***.framework/Versions/A/Frameworks/***.framework</string> </dict> </array> <key>RootRelativeBundlePath</key> <string>Library/Frameworks/***.framework</string> </dict></array></plist>

Run install commandpkgbuild --component-plist --identifier --install-location --root --version
