How to create a new Swift builder

• Open a file which contains one more structs you wish to generate a builder for.

Example:

class Foo {
    var name: String?
}

• Click Editor -> SourceEditorExtension -> Generate Builder.

Recommended: assign a shortcut

• Select preferences ⌘, in Xcode.
• Choose 'Key Bindings'.
• Search for 'Generate Builder'.
• Choose your preferred shortcut.

Usage example

Open a struct called Foo that we wish to generator a builder for:

struct Foo: Equatable {
    var isActive: Bool
    var city: String?
    var countryIsoCode: String? = Locale.current.regionCode
    let aboutMe: String?
    let quote: String?
}

Generate the builder:

struct FooBuilder {
	var isActive: Bool = false
	var city: String?
	var countryIsoCode: String?
	var aboutMe: String?
	var quote: String?
	func build() -> Foo {
		return Foo(
			isActive: isActive,
			city: city,
			countryIsoCode: countryIsoCode,
			aboutMe: aboutMe,
			quote: quote
		)
	}
}

Extract the generated builder into its own file if you like, or leave it close the original file. Then use the builder like:

var foo: Foo = FooBuilder(isActive: true).build()

Disable or remove the plugin

To disable:

Go to System Preferences -> Extensions and deselect the extension under Xcode Source Editor.

To remove:

Delete the app.

Extension doesn’t appear in my editor or in System Extensions

When multiple copies of Xcode are on the same machine, extensions can stop working completely. In this case, Apple Developer Relations suggests re-registering your main copy of Xcode with Launch Services"

$ cd /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support

$ ./lsregister -f /Applications/Your-Xcode.app
