Clarified and copyedited the descriptions of errors that are raised when attempting to remove a source from a style. Worded the changelog entry more generically because the same method in Swift throws an error instead of returning. A mismatch would occur if the identifier is used by a different source than the one being removed. An application could cause this error to occur by keeping a reference to an MGLSource after changing the style URL of an MGLMapView. Another way would be to remove a source from the style, add another source to the style with the same identifier, then attempt to re-remove the original source from the style.
Darwin
The code in the Darwin platform targets Apple platforms but is not specific to iOS or macOS. This code is not distributed as an SDK in itself, but is required by the Mapbox iOS SDK and Mapbox macOS SDK.
These files depend on the Foundation and Core Foundation frameworks but do not depend on iOS- or macOS–specific frameworks, such as UIKit or AppKit. Any non-cross-platform code is guarded by TargetConditionals.h macros.
