use of @import when modules are disabled
I got this warning in a zero-swift project whenever I tried to add the @import SafariServices; statement.
Solution:Enable the modules. Go to the Target > Build Settings and set the Enable Modules (C and Objective-C modules) to YES.
OR
Note: I haven't verified this potential solution, but probably worthy of consideration if there are side effects caused by this solution.
Rather than enabling modules to entire project, we can enable modules for a specific file which is importing c++ file. Go to build phases -> Compile Sources -> Select the file -> Add compiler flag
-fmodules
I've been mixing ObjC, ObjC++, C++, and Metal. Whenever I get the "use of @import when modules are disabled" I tryreplacing:
@import Name; with:
#import "Name/Name.h"example, replace:
@import Metal;@import MetalKit;@import CoreVideo;with:
#import "Metal/Metal.h"#import "MetalKit/MetalKit.h"#import "CoreVideo/CoreVideo.h"It seems to work.
