Question

I’m not sure what the issue is- I’m getting “cannot find interface declaration for Singleton”,
here: @implementation Singleton

and I’m getting “Singleton may not respond to +alloc”,
here: static Singleton *shared;

The .m file

#import "Singleton.h"

@implementation Singleton

+(Singleton *) sharedSingleton 
{
    static Singleton *shared;
    if (!shared) {
        shared = [[self alloc] init];
    }

    return shared;
}

@end

The .h file

#import <Foundation/Foundation.h>

@interface Singleton : NSObject {

}

+ (Singleton *)sharedSingleton;
@end

I just want a basic Singleton class 🙁 They appear as warnings but I want them gone if possible! Hopefully it’s not stupid, it’s been a long day

Answer 1

Try cleaning your project if still it doesn’t remove warning then
Change your line from

shared = [[self alloc] init];

to

shared = [[Singleton alloc] init];
