AssetChecker

AssetChecker is a tiny run script that keeps your Assets.xcassets files clean and emits warnings when something is suspicious.

Because Image Assets files are not safe, if an asset is ever deleted, nothing will warn you that an image is broken in your code.

Try it!

AssetChecker is part of freshOS iOS toolset. Try it in an example App! Download Starter Project

How

By using a script running automatically, you have a safety net that makes using Asset Catalog a breeze.

What

Automatically (On build)

• Raises Errors for Missing Assets
• Raises warnings for Unused Assets

Installation

Installation available via Cocoapods. Add the following to your Podfile:

pod 'AssetChecker', :git => 'https://github.com/freshOS/AssetChecker.git'

Or copy the script into your project.

Add the following Run Script in XCode, this will run the script at every build. If you installed via Cocoapods, you can use the following script:

${PODS_ROOT}/AssetChecker/run --catalog ${SRCROOT}/Resource/Images.xcassets

with arguments:

--catalog Absolute path to your Asset catalog (required)
--source Absolute path to your source directory.  Defaults to $SRCROOT

If you didn't use Cocoapods, use the path of where you copied AssetChecker script:

${SRCROOT}/{PATH_TO_THE_SCRIPT}/AssetChecker.swift ${SRCROOT}/Sources ${SRCROOT}/Resources/Images.xcassets

In this example your source files are located in /Sources and your Asset catalog is in /Resources/Images.xcassets.

And configure top section of the script :

// Configure me \o/
let sourcePath = "/Sources"
let assetCatalogPath = "/Resources/Assets.xcassets"
let ignoredUnusedNames = [String]()

Run and Enjoy \o/

False positives

Sometimes you're building the asset names dynamically so there is no way for AssetChecker to find out statically by looking at the codebase.

In this case the script will emit a false positive.

You can manually declare these false positives so that they get ignored !

Set the ignoredUnusedNames variable in the script file like so:

let ignoredUnusedNames = [
    "voteEN",
    "voteES",
    "voteFR"
]
