cocoapods / swift and SDWebImage imports

[desseim]

I tried to install UIActivityIndicator-for-SDWebImage through cocoapods and use it in a Swift project. As far as I checked pod install did its job correctly and UIActivityIndicator-for-SDWebImage links to SDWebImage.framework. In my project I

import SDWebImage
import UIActivityIndicator_for_SDWebImage

but the Swift compiler issues an error trying to build the Objective-C module UIActivityIndicator-for-SDWebImage. That error being it not finding UIImageView+WebCache.h at its import statement in UIImageView+UIActivityIndicatorForSDWebImage.h, which looks like this:

#import "UIImageView+WebCache.h"

I referred to the guide to cocoapods frameworks and after modifying the failing import statements to

#import <SDWebImage/UIImageView+WebCache.h>
#import <SDWebImage/SDImageCache.h>

(SDImageCache.h was failing too) it compiled.

I'm not experienced enough with the iOS toolchain and cocoapods yet to know whether the library files should actually be updated or if something is wrong with my project configuration, so "please advise" :)

Thanks!

By the way this edit in the SDWebImage recommendations seems to support the updating the import statements.

Any luck with this? =)

@moyoteg I solved the issue by simply changing it from #import "UIImageView+WebCache.h" to #import <SDWebImage/UIImageView+WebCache.h>

#import <SDWebImage/UIImageView+WebCache.h>
#import <SDWebImage/SDImageCache.h>

Should do the trick.
