Quickest way to add Carthage in Xcode Project

问题

What is quickest way to add dependencies in Xcode project using Carthage.

How to add or edit dependencies later.

回答1:

Install Carthage

Download Carthage

Open terminal

Terminal: cd ~/Path/To/Folder Containing Project

Create Carthage file as:

Terminal: touch Cartfile

Open Cartfile file from project folder and add required dependency

Example Cartfile file

github "Alamofire/Alamofire" == 4.5

github "Alamofire/AlamofireImage"

After Editing Cartfile file save it.

Run following command from terminal

Terminal: carthage update --platform iOS

xCode > Build phases

Plus button on top left > New Run Script Phases
Run Script > Shell script window > add following:

/usr/local/bin/carthage copy-frameworks

Run Script > Input file window > add following:

$(SRCROOT)/Carthage/Build/iOS/DependencyName.framework

Link Binary With Libraries > Plus button > Add Other > Navigate to Project Folder > Carthage > Build > iOS > Framework to add

Done

Installing Carthage
```
//Homebrew
brew install carthage
```
Create Cartfile file at the project(.xcodeproj)/workspace(.xcworkspace) directory
Modify Cartfile. Add necessary dependency == repo
```
github "<owner>/<repo>" == <version>
```
[Note] Any carthage command should be called from Cartfile folder

Run carthage update. High level logic:

`carthage update [dependency]` {
    - reads `Cartfile`, resolves dependency graph and generates `Cartfile.resolved` to store a list of versions that will be actually built

    //--no-use-binaries - this flag force a Carthage to not use a `Prebuilt framework`
    //--no-build - this flag skip a building step - `carthage build`

    `carthage bootstrap [dependency]` {
        - reads `Cartfile.resolved`
        `carthage checkout [dependency]` {
            `carthage fetch <path>` {
                - fetch dependency from `Cartfile.resolved` into `~/Library/Caches/org.carthage.CarthageKit/` folder
            }
            - checkout/move a dependency from `~/Library/Caches/org.carthage.CarthageKit/` to generated `Carthage/Checkouts` folder
        }
        `carthage build [dependency]` {                
            - builds all `shared frameworks schemes` from `Carthage/Checkouts` into generated `Carthage/Build` folder

            //--no-skip-current - this flag also builds all `shared frameworks schemes` of a consumer workspace/project(in addition to `Carthage/Checkouts` folder)
        }
    }
}

Drag and drop builded frameworks to General -> Frameworks and Libraries

Run the next script. This step is important because carthage build process a fat binary(arm64... + x86_64) using lipo[About]. Apple reject application which uses it. That is why you should add this extra step to cut architecture for simulator(x86_64)

Build Phases -> + -> New Run Script phase -> 

    // /usr/local/bin/carthage - path to Carthage, copy-frameworks - command which sets a necessary architecture and copies framework to an application bundle
    Shell -> /usr/local/bin/carthage copy-frameworks

    //path to a generated Carthage/Build
    Input files -> + -> $(SRCROOT)/Carthage/Build/<platform>/<name>.framework
