macOS How to access and use a dylib in an Obj-C application?

[MatthewF]

I've made a dylib that contains the following code:

Test.h:

#import <Cocoa/Cocoa.h>
@interface Test : NSObject {
     int number;
}
-(void)beep;
-(void)giveInt:(int)num;
-(int)takeInt;

@end


Test.m:

#import "Test.h"

@implementation Test

-(void)beep {
     NSBeep();
}
-(void)giveInt:(int)num {
     number = num;
}
-(int)takeInt {
     return number;
}

@end

I've compiled the dylib and put it in another project but I can't seem to figure out how to make a Test object from the dylib and call some of the methods.
Anyone know how to do this?
Thanks,
Matt
