Cocoa Touch Objective-C框架中的Swift类

Question

I'm trying to build a Cocoa Touch Framwork (XCode 6, obviously) with Objective-C and some Swift classes.

I've successfully added Swift classes to regular projects (no framworks) before so I'm aware of the build settings required for this ( Embedded Content Contains Swift Code ). Unfortunately, the framework project doesn't build the header file ( projectName-Swift.h ) and I'm not able to import the class and the Swift classes into any of my .m files.

Does anybody know why this wouldn't work, and what build settings I need to change in order to make this work?

Answer 1

Finally found the answer;

Within the frameworks the import statement for Swift files has to look as follows;

#import <ProjectName/ProjectName-Swift.h>

instead of

#import "ProjectName-Swift.h"

Sometimes it helps to RTFM ( https://developer.apple.com/library/ios/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html#//apple_ref/doc/uid/TP40014216-CH10-XID_82 )

Answer 2

I've struggled with this for a while because I don't think the documentation is clear. I have a slightly different project setup, and it's taken me a while to work this out so I thought I'd answer here.

I have a project with name: MyProject In this project, I have a framework: MyFramwork

I have a swift file in MyFramework which I want to import into an objective c file in MyFramework.

To do this, you need:

#import <MyFramework/MyFramework-Swift.h>

NOT

#import <MyProject/MyFramework-Swift.h>

Hope that helps someone.
