It's a change in Xcode 8.2 - NSThread.isMainThread in ObjC land is now a class property:
@property (class, readonly) BOOL isMainThread NS_AVAILABLE(10_5, 2_0); In Xcode 8.1(and since iPhone OS 2) it was a regular old-school class method: + (BOOL)isMainThread NS_AVAILABLE(10_5, 2_0) and so it loses the paren requirement now. ++md On Wed, Jul 13, 2016 at 10:13 AM, Nate Birkholz via swift-users < swift-users@swift.org> wrote: > Is this a change to NSThread in the release, or to the language, dropping > empty () when calling methods?
