Installation

Basic

You can add DeclarativeConfiguration to an Xcode project by adding it as a package dependency.

  1. From the File menu, select Swift Packages › Add Package Dependency…
  2. Enter "https://github.com/maximkrouk/weak" into the package repository URL text field
  3. Choose products you need to link them to your project.

Recommended

If you use SwiftPM for your project, you can add DeclarativeConfiguration to your package file. Also my advice is to use SSH.

.package(url: "git@github.com:maximkrouk/weak.git", .branch("main"))

or

.package(url: "git@github.com:maximkrouk/weak.git", .exact("1.0.0"))

Do not forget about target dependencies:

.product(
    name: "Weak", 
    package: "Weak"
)
