Failed to import bridging header

Question

I\'ve read a lot of questions and answers that deal with a similar issue, but I have yet to find a solution. If anyone could shed some light, that would be wonderful.

Answer 1

I answered this in another post: Chartboost integration issues with XCode 6.1

EXPLANATION:

It seems like some pods and libraries don't bother importing the basic frameworks as they expect your code to already have them. This doesn't work with Swift as the way to import frameworks changed. All you need to do is to add the frameworks needed in your bridging header file.

ANSWER:

It depends on what errors the compiler throws. If it complains about NSObject, NSString, etc... you need to add #import <Foundation/Foundation.h> in the top of your bridging header file.

If it complains about UIView, UIButton, etc... you need to add #import <UIKit/UIKit.h> in the top of your bridging header file.

Answer 2

The problem like your's puzzled me. But I found a solution.

#import <Foundation/Foundation.h>

You should put this code (↑) before your code. This is just my solution (↓).

#import <Foundation/Foundation.h>
#import <Chartboost/Chartboost.h>

Good luck!

Answer 3

The answer is really very simple.

Make sure you are adding your bridging header path in SWIFT_OBJC_BRIDGING_HEADER under the target section instead of the project section.

Answer 4

Had a nearly identical issue and found a solution that worked for me.

My problem was that the Bridging Header was not in ALL my targets.

It was in my project but not my UnitTest target. So I added it to by my UITest and UnitTest and it started working without issue.

Answer 5

This is how I solved it (and works!):

1. Create yourProjectName-Bridging-Header.h file at the root of your project
2. Include in that file the .h of the classes you want to expose and use into your swift project
3. Go to yourProject->Build Settings->Search Paths, and set to Yes the "Always Search User Paths" key.
4. Set "User Header Search Paths" to your project root path.

That's it.

Apparently, Xcode miss out on third party folders when they are copied into your project

I am on Xcode 6.3 , swift 1.2.

Answer 6

I figured out 2 solutions!

1) This isn't the prettiest way to do it, but I copy and pasted all my code from my Chartboost.h file into my Bridging-Header.h file instead of importing . This worked. But I knew there was a better way, so I kept hunting...

2) The correct solution, I believe, is what I did next. My project's (not target) Framework Search Paths was empty. So, I went ahead and added the path to the Chartboost SDK like so: /Users/me/Desktop/Apps/SDKs/Chartboost
Now it builds and runs with no problem and I didn't have to copy and paste everything into the bridging header. All that was needed was

#import <Chartboost/Chartboost.h>

If anyone is having a similar issue, just read what I did in my question, and then follow it up with this answer.
