AssetsPre13

What

AssetsPre13 is an iOS framework to manage a variety of assets, applicable to iOS versions from 11.0 up to but not including 13.0. Its main advantages are:

modularity: your application assets are organised in a single module, separate from the rest of your application
type safety: assets are accessed via enumeration values (which you define), rather than string literals
uniform API: AssetsPre13 manages Strings, Images, and Colors, using a uniform pattern, like so:

Assets.color(.backgroundMainView)
Assets.image(.doneButton)

It achieves its goals by relying on another library of mine, AssetCatalogAwarePre13, which is responsible for defining the various protocols and functions required to manage assets. This separation of concerns is what allows AssetsPre13 to be customisable to your heart's content.

An example project for UIKit is provided. Here are the relevant parts, illustrating how AssetsPre13 is used in practice:

import AssetsPre13

class ViewController: UIViewController {

    @IBOutlet private var exampleView: UIView!
    @IBOutlet private var exampleLabel: UILabel!

    override func viewDidLoad() {

        super.viewDidLoad()

        self.view.backgroundColor = Assets.color(.backgroundMainView)
        exampleView.backgroundColor = Assets.color(.backgroundExampleView)
        exampleView.layer.cornerRadius = 20
        exampleLabel.text = Assets.string(.exampleText)

    }

}

Dependencies

AssetsPre13 depends on anoher library of mine, AssetCatalogAwarePre13.

Installation

At the moment, AssetsPre13 can only be installed by cloning or downloading its GitHub repository. I'm waiting for the Swift Package Manager to support resources so I can turn it into a proper package, since I'm moving away from CocoaPods and Carthage.

Newer iOS versions

AssetsPre13 is meant to be used with versions of iOS below 13.0. If you need to support newer versions, you might want to look at Assets, instead.
