Currier

Currier transforms any Swift function into a curried version of that function. This is achieved by wrapping it in a simple 'curry' call.

Given the following function:

func myMultiply(first: Float, second: Int) -> Double {
    return Double(first) * Double(second)
}

Currier will produce a curried version:

let curriedMultiply: (Float) -> (Int) -> Double = curry(myMultiply) // Currier used here!

let multiplyByTwo: (Int) -> Double = curriedMultiply(2.0) // Partial application

let result: Double = multiplyByTwo(10)

assert(20 == result) // Assertion true

The previous example can be condensed down to the following:

let sameResult = curry(myMultiply)(2.0)(10)

The unit tests provide examples of calling the curry function using different numbers of parameters. The version of the function which takes two parameters is explicitly typed and commented.

Requirements

There are no external requirements for this project, just Swift.

• iOS 8.0+ / macOS 10.9+ / tvOS 9.0+ / watchOS 2.0+
• Xcode 11+
• Swift 5.1+

For older versions of Swift and Xcode, please see prior releases.

Installation

Swift Package Manager

The Swift Package Manager is the official tool for managing the distribution of Swift code. It is currently only available for all Apple platforms. It can also be used with Linux but this project does not fully suppourt that at this point.

If you use it to manage your dependencies, simply add Currier to the dependencies value of your Package.swift file.

dependencies: [
.package(url: "https://github.com/tigerpixel/Currier.git", from: "1.3.0")
]

Cocoapods

Currier is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "Currier"

Carthage

If you use Carthage to manage your dependencies, simply add the following line to your Cartfile:

github "tigerpixel/Currier"

If you use Carthage to build your dependencies, make sure you have added Currier.framework to the "Linked Frameworks and Libraries" section of your target, and have included them in your Carthage framework copying build phase.

Git Submodule

1. Add the Currier repository as a submodule of your application’s repository.
2. Run git submodule update --init --recursive from within the Currier folder.
3. Drag and drop Currier.xcodeproj into your application’s Xcode project or workspace.
4. On the “General” tab of your application target’s settings, add Currier.framework. to the “Embedded Binaries” section.
5. If your application target does not contain Swift code at all, you should also set the EMBEDDED_CONTENT_CONTAINS_SWIFT build setting to “Yes”.
