Factored out redundant tile URL template documentation from the MGLRasterSource and MGLVectorSource documentation into a jazzy guide. This documentation used to live in one place, on a method on MGLTileSource, but that method had to be moved to MGLTileSource’s concrete subclasses. A jazzy guide is easier to link to, in any case.
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.
