Buildable

Buildable comes with a protocol and functions for you to implement Builder Design Patters.

// DEMO 1: static method from the Buildable NSObject
let icon: UIImageView = .create {
    $0.image = UIImage(systemName: "checkmark.seal.fill")
    $0.tintColor = .systemBlue
    $0.contentMode = .scaleAspectFit
    $0.isUserInteractionEnabled = true
}

Xcode

In Package Dependencies inside your project file paste the repo url https://github.com/bogue89/Buildable in the field "Search or Enter Package URL".

Demos

Build simplifies declarations, works well with property wrappers, and it works with @autoclosures so the work is done only when need it

// DEMO 2: infering type from builder
lazy var tap = build {
    UITapGestureRecognizer(target: self, action: #selector(tapped))
}

Conforming to Buildable implements by default a setup method

// DEMO 3: setup with reference
var animation = CABasicAnimation(keyPath: "opacity").setup {
    $0.toValue = 0.2
    $0.duration = 0.2
    $0.autoreverses = true
}

You can use the setup to swap values and throw errors

// DEMO 4: setup with reference
try buildWithError(.touches(times: taps)) {
    guard case .touches(let times) = $0 else { return $0 }
    if times > 3 {
        throw NSError()
    } else if times > 2 {
        return .warning
    }
    return $0
}
