What if setting arbitrary constraints, views, and behaviors for specific trait collections was as easy as:
let exclusiveButton = UIButton(type: .System) let traits: [AdaptiveAttribute] = [ Idiom.Phone, Scale.TwoX, ForceTouch.Available, SizeClass.VerticalRegular, SizeClass.HorizontalCompact, ] addViewFor(traits, view: exclusiveButton, to: view, withConstraints: [ exclusiveButton.centerXAnchor.constraintEqualToAnchor(view.centerXAnchor), exclusiveButton.centerYAnchor.constraintEqualToAnchor(view.centerYAnchor), ])
UITraitEnvironment is just too cool to be limited to views and view controllers!
Briggs seeks to provide a crucial missing component in Apple’s API:
UITraitEnvironment.addChildTraitEnvironment:, and adds a healthy dose of sugar to
AdaptiveElement: The child—receives trait collection information
AdaptiveInterface: The parent—provides trait collection information
AdaptiveAttribute: The trait—describes trait collection information
AdaptiveBehavior: Associates a behavior and counter-behavior with a set of traits
Behavior is executed if incoming traits match, else counter-behavior is executed.
AdaptiveConstraintContainer: Associates a set of constraints with a set of traits
Constraints are activated if incoming traits match, else they are deactivated.
AdaptiveViewContainer: Associates a view with a set of traits
View is added to hierarchy if traits match, else view is removed.

- Xcode 7.3+
CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:
$ gem install cocoapods
To integrate Briggs into your Xcode project using CocoaPods, specify it in your
source 'https://github.com/CocoaPods/Specs.git' platform :ios, '9.0' use_frameworks! target '<Your Target Name>' do pod 'Briggs', '~> 2.0.0' end
Then, run the following command:
$ pod install
Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
You can install Carthage with Homebrew using the following command:
$ brew update $ brew install carthage
To integrate Briggs into your Xcode project using Carthage, specify it in your
github "auswahlaxiom/Briggs" ~> 2.0.0
carthage update to build the framework and drag the built
Briggs.framework into your Xcode project.
If you prefer not to use either of the aforementioned dependency managers, you can integrate Briggs into your project manually.
- Open up Terminal,
cdinto your top-level project directory, and run the following command if your project is not initialized as a git repository:
$ git init
- Add Briggs as a git submodule by running the following command:
$ git submodule add https://github.com/auswahlaxiom/Briggs.git
Open the new
Briggsfolder, and drag the
Briggs.xcodeprojinto the Project Navigator of your application's Xcode project.
It should appear nested underneath your application's blue project icon. Whether it is above or below all the other Xcode groups does not matter.
Briggs.xcodeprojin the Project Navigator and verify the deployment target matches that of your application target.
- Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the "Targets" heading in the sidebar.
- In the tab bar at the top of that window, open the "General" panel.
- Click on the
+button under the "Embedded Binaries" section.
- You will see two different
Briggs.xcodeprojfolders. It does not matter which one you select the framework from.
Briggs.frameworkis automagically added as a target dependency, linked framework and embedded framework in a copy files build phase which is all you need to build on the simulator and a device.
