4 Test target
4 xcconfigs
4 framework projects

11.
Configurations

12.
Create a project

13.
Clean up files and add
main.swift

14.
Add a framework

15.
Run Carthage
carthage update --use-submodules
github "Carthage/Commandant"
github "jspahrsummers/xcconfigs"
github "ishkawa/APIKit"
github "ikesyo/Himotoki"

16.
Set xcconfigs

17.
Run bootstrap script
objc-build-scripts: standardize
how Objective-C projects are
bootstrapped after cloning

18.
New workspace
Add all the projects into here

19.
Add frameworks
General → Linked Frameworks
and Libraries

20.
Copy frameworks in
Build Phrases
Destination is frameworks

21.
Runpath in Buld Settings for
main target
/Library/Frameworks/***.framework/
Versions/Current/Frameworks/

22.
Embedded Content Contains
Swift Code for framework
target
Set to YES, default is NO

23.
Add components.plist for
pkgbuild command
<plist version="1.0">
<array>
<dict>
<key>BundleIsVersionChecked</key>
<false/>
<key>BundleOverwriteAction</key>
<string>upgrade</string>
