FOUNDATION_EXTERN is an alias for extern in most cases, but also covers us in the event that a method could be mismangled by the compiler as C++ (when we want C-style mangling, for Obj-C compatibility).
This adds two new convenience initializers to MGLShapeSource:
-initWithIdentifier:features:options: takes an array of shape objects
that conform to MGLFeature, inserts them in a shape collection feature
and creates a source with that shape. -initWithIdentifier:shapes:options
does the same but with concrete MGLShape objects that get added to
a shape collection.
Throw an exception if an shape source is created with the features
initializer but is sent an array of features that contains something
that is not actually an object that conforms to the feature protocol.

* [ios, macos] Made MGLMapView.style property nullable
MGLMapView’s style property is now nullable (optional in Swift). The property is set to nil while the style loads and in the event that the style has failed to load.
* [ios, macos] Switch to delegate method
* [macos] Create MGLMapView programmatically for layer tests
When MGLMapView is created via a nib, -initWithCoder: is called, causing styleURL to be set to nil, in turn causing the default Streets style to be loaded, fooling MGLStyleLayerTests into thinking one-line has been loaded. Instead, create MGLMapView programmatically, passing the intended style URL into the initializer, preventing Streets from being loaded.
* [ios, macos] Removed extraneous code fences
* [ios] Streamlined example delimiters
Use test method names as names of example blocks and test method documentation comments as front matter for examples. Set off example blocks using a syntax similar to playground markup syntax. Avoid hard-coding indentation levels. Trigger Xcode build error when an error occurs in the script.
* [ios] Removed platform-specific code from examples
* [ios] Fixed logic error
The comment said 200 while the code said 1,500.
* [ios] Formalize build phase input
* [ios] Insert examples into original source documentation
Rewrote the example code insertion script to work on the original source files and overwrite any existing code examples on the same symbols. The script uses SourceKitten to find the documentation comment for the symbol named by the test method.
Replaced the Run Script build phase that runs the example code insertion script with a make rule that runs the same script. Inlined skeleton examples minus the contents of the code blocks.
* [ios] Fixed syntax error
* [ios] Ran ios-add-examples-to-docs
* [ios] Avoid touching unchanged headers
* [ios] Refactored example insertion script
* [ios] Point jazzy at original sources
* [ios] Invoke SourceKitten only once
* [ios] Look for methods as well as properties
* [ios] Thoroughly search for code blocks in doc comments
Refactored the example code insertion script to index test methods by their names, then recursively search the SourceKitten output for documentation comments that contain Swift code blocks, replacing each code block with the associated test method body.
* [ios, macos] Enabled example insertion for macOS
The example code insertion script is now platform-agnostic.
* [ios, macos] Fixed documentation example tests
Set the map view’s style to a minimal local JSON file. Wait for the style to finish loading before running each test. Corrected CGVector type.
* [ios, macos] Dry run mode
The output of this mode isn’t a good indicator of whether any files would’ve needed to be changed, because the presence of a conditional compilation block in one of the test methods means this script would always change and revert the corresponding comment.
* [ios] Fixed test failure
The iOS implementation of MGLMapView tries to show the Streets style by default even if no access token has been set. Avoid a race condition and frequent test failure by specifying the minimal style on initialization.
* [ios, macos] Ensure SourceKitten is installed before inserting example code
* [ios, macos] Tear down map view after each test
Keep map views from previous tests from hanging around, potentially obscuring the result of a subsequent test. Set the access token to a bogus token upfront for all style layer tests. Unified MGLStyle usage within MGLStyleTests.
* [ios, macos] Reinsert examples after generating runtime styling headers
* [ios, macos] Audited source headers for nullability
* [macos] Made MGLTileSet public
* [ios, macos] Replaced MGLTileSet with MGLTileSource
MGLRasterSource and MGLVectorSource now share a common abstract superclass, MGLTileSource. MGLTileSet has been removed. MGLTileSource is modeled after mbgl::style::RasterSource and mbgl::style::VectorSource. It has initializers that incorporate the parameters of MGLTileSet’s initializers, but it lacks getters for everything but the attribution string. MGLTileSet’s properties have been converted into options that can be passed into MGLTileSource’s initializers in a dictionary.
Properly implement rawSource as a covariant property so that it doesn’t end up getting autosynthesized as a shadow ivar. This prevents concrete subclasses of MGLSource from setting _rawSource directly but getting a different value out of self.rawSource.
Marked -[MGLSource init] as unavailable and ensured that concrete subclasses of MGLSource have the right set of initializers marked as designated initializers.
Documentation comments for each concrete source class identify the corresponding source type in the style specification. Clarified the purpose of MGLTileSetScheme, now known as MGLTileCoordinateSystem.
* [ios, macos] Clarified tile size interpretation
Sticking to a default value of 256 for mapbox: URLs, but other URLs get the standard 512 value.
* [ios, macos] rawSource is always set
* [ios, macos] Cleaned up MGLShapeSource initialization
rawSource is never nil, so there’s no need for a -commonInit method. Extracted -geoJSONOptions from MGLShapeSource into a standalone function for easier testing.
* [ios, macos] Synchronized headers in project
Realphabetized headers in groups. Added headers missing from one project or the other.
* [ios, macos] Added MGLShape methods to (de)serialize GeoJSON data
Added a class initializer and instance method to MGLShape that deserialize and serialize the shape as GeoJSON data, respectively. The new initializer handles parsing errors gracefully.
Removed methods specific to GeoJSON data from MGLShapeSource, in an effort to reduce parallel state. Developers are now expected to go through the new MGLShape initializer to get an MGLShape representation. Alternatively, a local file URL can be passed into the other MGLShapeSource initializer.
* [ios, macos] Typo in assertion message
* [ios, macos] Simplified GeoJSON serialization
Every MGLShape now knows its most specific mbgl::GeoJSON representation.
* [ios, macos] Reremoved MGLFeaturePrivate
mbgl::GeoJSON, which is a variant, allows a single GeoJSON representation method to traffic in whatever type is needed for a particular shape class. This change removes some hidden private protocols, which are a bug waiting to happen.
* [ios, macos] Fixed covariant rawLayer property
Properly implement rawLayer as a covariant property so that it doesn’t end up getting autosynthesized as a shadow ivar. This prevents concrete subclasses of MGLStyleLayer from setting _rawLayer directly but getting a different value out of self.rawLayer.
* [ios, macos] Use MGLAttributionInfo for source attribution
Made MGLAttributionInfo public. Replaced MGLTileSource’s attribution property with an attributionInfos property set to an array of MGLAttributionInfo objects. Added an MGLTileSourceOption for specifying an array of MGLAttributionInfo objects instead of an HTML string (either is acceptable when creating an MGLTileSource).
* [ios, macos] Corrected method references in documentation
