Cannot find interface declaration for 'NSColor'; did you mean 'NSCoder'? #13

I am getting this error on compile while using HexColors and TSMessages along with about 20 more errors, all related to HXColor.

ok, that's strange. can you hand in more information for your project?

Hi Marius,

problem solved, it was my fault (error in PrefixHeader.pch).

Cheers,

Paolo

Getting same error with TSMessage - removed from my project and just added the implementation files here and multiple errors all related to NSCOLOR.

New project, iOS8 - I have no PrefixHeader.pch but adding one does not solve errors. Any ideas?

Minimum PCH content

#ifdef __OBJC__
#import <UIKit/UIKit.h>
#import "HexColor.h"
#endif
Gob-Lin commented 9 years ago

Problem resurfaced with iOS8 project. Tried adding PrefixHeader.pch with both previous content and the minimum suggested by SoundBlaster to no avail. Can't use TSMessages anymore :-(

iOS 8 only projects are default working with modules. If you use modules the PrefixHeader.pch is not necessary an more. You have to link the .pch in your build target.

after upgrading to xcode 6.3, I'm experiencing a similar issue in a Swift iOS project. the project will not compile.

I resolved it by importing <UIKit/UIKit.h> before #import "HexColor.h" inside the objc to swift bridging header:

//
//  Use this file to import your target's public headers that you would like to expose to Swift.
//

#import <UIKit/UIKit.h>
#import "HexColor.h"
...

got the same problem here. the main reason is that TARGET_IPHONE_SIMULATOR and TARGET_OS_IPHONE is linked in UIKit and we are depending on that for the OSX Support. Maybe not the best idea here ;)

Any suggestion to fix this?

mRs- commented 9 years ago

current solution in the example project: https://github.com/mRs-/HexColors/blob/develop/Classes/HexColor.h#L15

aporat commented 9 years ago

would including TargetConditionals.h in #import "HexColor.h" work for osx as well? http://stackoverflow.com/questions/24664649/conditional-compiling-of-objective-c-in-a-swift-project

mRs- commented 9 years ago

seems to work fine!

mRs- commented 9 years ago

@aporat does it work for you now without importing UIKit in the bridging header?

aporat commented 9 years ago

yeah, that solution works fine with swift projects (atleast for ios)
