Also:
- Change some #imports to directly refer headers instead of going though the framework header because it enables it be included as a module through Cocoapods.
- Improve unit test encapsulation by making some classes (recorders) and methods available in the private header
Compilation time after you modify a header file has been greatly improved by avoiding including the umbrella headers (ResearchKit.h and ResearchKit_Private.h) in any of the framework files.
Also:
- Restructure .m files #import section into a hierarchy of alphabetically sorted subsections separated by one newline (1. local views and controls; 2. view controllers and recorders; 3. model files; 4. general files and helpers, 5. iOS frameworks). The #import order follows advice found here: http://qualitycoding.org/import-order/
- Remove needless and duplicate imports from .m files
- Make sure all headers include at least Foundation or UIKit; except Private or Internal headers which only include their own class header at the next public level
- Rename ORKHelpers.h to ORKHelpers_Internal.h (it is not public, and its name was misleading given that we also have ORKHelpers_Private.h).
- Add a few missing NS_ASSUME_NONNULL_BEGIN/NS_ASSUME_NONNULL_END annotation in headers
- Add a few missing double newline before and after import section
- Fixes tests to reflect the new empty answer for a Choice Answer Format being ORKNullAnswerValue() instead of an empty array (introduced on the Review Step feature).
- Fixes test for task step identifier uniqueness validation (it now takes place on task init).
