Builder

Builder Patterns for Flexible Syntax in Swift

Installation

Builder was deployed as Swift Package Manager. Package to install in a project. Add as a dependent item within the swift manifest.

let package = Package(
    ...
    dependencies: [
        .package(url: "https://github.com/pelagornis/swift-builder.git", from: "1.1.0")
    ],
    ...
)

Then import the Builder from thr location you want to use.

import Builder

And then adding the product to any target that needs access to the library:

.product(name: "Builder", package: "swift-builder"),

Documentation

The documentation for releases and main are available here:

• main

Using

Initializer UIView with Builder

let view = UIView()
    .builder()
    .translatesAutoresizingMaskIntoConstraints(false)
    .backgroundColor(.systemBlue)
    .build()

This is equivalent to

let view: UIView = {
    let view = UIView()
    view.translatesAutoresizingMaskIntoConstraints = false
    view.backgroundColor(.systemBlue)
    return view
}()

Want to use with your own types? Just make extensions.

extension MyType: Buildable {}

let instance = MyType()
    .builder()
    .property("some value")
    .build()

Support Macros

Starting with Swift version 5.9, @Builder macro is supported.

@Builder
struct Pelagornis {
    var libraryName: String?
}
