The best way to create constraints in code.

• Semantic. Align APIs focus on your goals, not the math behind Auto Layout constraints.
• Powerful. Create multiple constraints with a single line of code.
• Type Safe. Makes it impossible to create invalid constraints, at compile time.
• Fluent. Concise and clear API that follows Swift API Design Guidelines.
• Simple. Stop worrying about translatesAutoresizingMaskIntoConstraints and constraints activation.

To give you a taste of what the semantic APIs look like, here is an example:

view.anchors.edges.pin(insets: 20, alignment: .center)

Documentation

The documentation for Align is created using DocC and covers all of its APIs in a clear visual way. There is also a cheat sheet available that lists all of the available APIs.

Requirements

Align	Swift	Xcode	Platforms
Align 3.0	Swift 5.6	Xcode 13.3	iOS 12.0 / tvOS 12.0 / macOS 10.14
Align 2.0	Swift 5.1	Xcode 11.0	iOS 11.0 / tvOS 11.0 / macOS 10.13

Why Align

Align strives for clarity and simplicity by following Swift API Design Guidelines. Although most of the APIs are compact, it is a non-goal to enable the most concise syntax possible.

Align is for someone who:

• Prefers fluent high-level APIs
• Doesn’t want to depend on big, complex libraries – Align has only ~330 lines of code
• Prefers to have as little extensions for native classes as possible – Align adds a single property: anchors
• Doesn’t overuse operator overloads, prefers fast compile times
• Likes NSLayoutAnchor but wishes it had simpler API which didn’t require manually activating constraints
