How to update just one library from the Cartfile with Carthage?

Question

My Cartfile has many libraries. When I do carthage update it goes through all the libraries. That can take very long time.

Is there a way to update just a s

Answer 1

Swift 5

//MARK:- Step 1
carthage update KeychainAccess --platform iOS

carthage update SDKNAME(like i mention KeychainAccess upper) --platform iOS

if you face an Error like this

//MARK:- If this error occur
error: unable to find utility "xcodebuild", not a developer tool or in PATH

Then use Part 1 in Terminal Again

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

and again

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

Answer 2

From 0.12 version build, checkout, and update take an optional space separated list of dependencies

For a Cartfile like the following

github "Alamofire/Alamofire"
github "ReactiveX/RxSwift"

You could choose to update one dependency

carthage update Alamofire

or multiple dependencies

carthage update Alamofire RxSwift

If you need to add flags, add them last:

carthage update Alamofire --platform iOS

Answer 3

[carthage update flow]

carthage [update|bootstrap|checkout|build] [dependency1] [dependency2] [--no-use-binaries] [--platform <name>]

//--no-use-binaries - does not use prebuild binary and use source code
//--platform - specify a platform

The longest phase is a build step[xcodebuild] because:

1. fat binary is built using lipo[About]

2. Carthage builds all shared frameworks schemes of a project. If you know which exactly schema which you need you can:

   • Leave specific schemes at xcschemes folder .../Carthage/Checkouts/<dependency>/<project>.xcodeproj/xcshareddata/xcschemes/<schema>.xcscheme

   • Open built project from Carthage/Checkouts folder -> Manage Schemes... -> leave specific schemes
