Xcode’s static library template comes with the -ObjC linker flag by default. Instead of removing that flag, this change removes the various imperfect workarounds we’ve been using to ensure that private SDK categories link. Given the size decrease in this static library since #2966 was fixed, we should have room to spare for the more straightforward approach. Moreover, an application that uses MGLMapView in a storyboard no longer needs to add -ObjC to the application target, which bloated the entire application, including other frameworks that had no need for -ObjC. -ObjC isn’t even needed for dynamic frameworks, and the OS X SDK is only built as a dynamic framework.
Darwin
The code in the Darwin platform targets Apple platforms but is not specific to iOS or OS X. This code is not distributed as an SDK in itself, but is required by the Mapbox iOS SDK and Mapbox OS X SDK.
These files depend on the Foundation and Core Foundation frameworks but do not depend on iOS- or OS X–specific frameworks, such as UIKit or AppKit. Any non-cross-platform code is guarded by TargetConditionals.h macros.
