I tried replicating this myself and couldn’t. Specifically, in Xcode 8.0:
1. I created a command line tool project
2. added `test.swift`, which looks like this:
import Foundation
extension DispatchQueue {
func foo() {
}
}
extension NSCoder {
func bar() {
}
}
3. added an Objective-C class which imported <xxx-Swift.h>, where `xxx` is the
target name
It built just fine. Looking at <xxx-Swift.h>, I see `bar` generates code like
this:
@interface NSCoder (SWIFT_EXTENSION(xxst))
- (void)bar;
@end
but I see no reference to `foo` or `OS_dispatch_queue`. What am I missing here?
Other than your bug number (-: Please post that.
Share and Enjoy
