Fixes

• Fixed a warning when compiling using -Wconversion. f58e4b240af1aa1f17cb5c474746a675bb23d896

• Fix a compilation issue when targeting OS X 10.7

• Enhance the autoCreateConstraintsWithoutInstalling: API to return an array of created constraints
• Add a new API to set the size of an array of views
• Fix a constraint exception when distributing views

• Add support for using PureLayout in App Extensions. See this page for more details.

• Use a new method to determine the UI layout direction (thanks @vytis)
• Make activating and deactivating constraints more efficient in some cases

• Make the constraint identifier APIs available on Mac OS X, as long as the SDK is at least 10.10 (will work with deployment target of 10.9 or higher)
• Fix issues with nesting constraint blocks (nested calls to autoSetPriority:, autoSetIdentifier:, etc)
• Don't set the priority of constraints when installing them unless inside a constraints block

PureLayout v2.0.0 is a major release, with many new features, APIs, and enhancements. The v2.0.0 release is fully backwards compatible with Xcode 5 and iOS 6 and 7 deployment targets (OS X deployment target remains at 10.7 as well).

Changes include:

• Full support for new features in iOS 8 SDK (first baseline and all layout margin attributes, active & identifier properties on NSLayoutConstraint)
• New API to constrain views to the iOS 8 layout margin attributes
• New API to prevent automatic installation of constraints
• Improved Swift compatibility using a new combined enum type ALAttribute
• Modified existing APIs to distribute views for naming & type consistency
• Deprecation of the constraint removal API on UIView
• Internal enhancements and optimizations

• Add a new API to allow distributing views with fixed spacing but without matching all their sizes (relying on each view's intrinsic content size instead)

• Add a Foundation import which enables Swift compatibility using a bridging header
