0.3.8

Fixes

Disable code flow instrumentation build setting (GCC_INSTRUMENT_PROGRAM_FLOW_ARCS)

Speed up theme source observation with deep source directories and theme hierarchies (#91)

Fixes an issue that could cause some classes to not resolve superclass properties (#90)
Project updates for Xcode 8 (#89)

Fixes an issue that could cause an EXC_BAD_ACCESS when an error occurred while creating a theme (#81)
Fixes an issue where multiple inter-theme constant references could fail to resolve by recursively resolving constant references (#82)

The Motif CLI now uses nullability annotations and modular imports in generated Objective-C symbols files (#76)

Migrates to NSErrors to communicate theme application failure in place of runtime exceptions. applyClassWithName:toObject: is now applyClassWithName:to:error: and applier blocks and value transformers are expected to populate a pass-by-reference NSError in the case of failure. (#67)
Applying the same theme class twice in a row does not perform the work of applying twice. This is helpful in the context of reusable views where performance is critical. (#70)
Adds support for Swift symbol output from the Motif CLI by passing the -s or --swift flag. (#56)
Fixes a logic error that could cause the Motif CLI to display an error when there wasn't one when generating theme files. (#57)
Adds annotations for Obj-C lightweight generics. (#60)
Removes Example project's dependency on Masonry in place of UIStackView. (#61)

Mapped constant values are now cached to prevent unnecessary overhead of requesting them on each access. (#75)
Codebase cleanup (#62, #63, #64, #65, #68, #69, #71, #72, #73)

Adds support for YAML in addition to JSON as a much more human-friendly way of writing your theme files. See the README for some examples (#38)
- Of course, while YAML is now the recommended way of writing theme files, JSON will still work
Adds a class method to NSValueTransformer to enable easy registration of Motif value transformer subclasses without having to declare a new interface & implementation (#28)
Removes the need specify value transformer names as part of applier registration (#43)
Adds default value transformers for the following: (#42)
- Creating UIEdgeInsets from an array, dictionary, or number in a theme file
- Creating CGSize from an array, dictionary, or number in a theme file
- Creating CGPoint from an array, dictionary, or number in a theme file
- Creating UIOffset from an array, dictionary, or number in a theme file
Removes old string value transformers in favor of the above
Adds a keyword applier registration method for easily specifying enums as strings in themes (#31)

Fixes a YAML number parsing bug (thanks @jlawton!) (#44)
Removes backwards-compatible nullability annotations as Xcode 6.3+ is standard now. (#40)
Uses modular imports in headers (#32)
Re-throws non-NSUndefinedKeyException exceptions when applying classes (#30)
Handles duplicate appliers with different classes (#29)
Inlines applier blocks to work around rdar://20723086 (#37)
Prevents Carthage from building the tests as part of build 3cc0695
Overrides missing designated initializer (#46)

Catch theme class application exceptions when live reloading themes
Improve theme class application exception copy to better communicate ways to resolve issue

Add live reloading dynamic theme applier, see the section in the README for documentation

Remove unused git submodules from repo
Add warning to screen brightness example when run on simulator
Ensure that a theme class reference is not applied to a theme class property
Fix compilation errors when integrated with an Objective-C++ project
Suggest load instead of initialize in Objective-C, due to initialize being called multiple times in categories, which could lead to duplicate appliers being registered
