Calling Custom Method Inside SKSpriteNode Not Working

I have a custom SKSpriteNode object and want to call a custom method inside it "Set Defaults". 

#import <SpriteKit/SpriteKit.h>

@interface Platform : SKSpriteNode

- (instancetype)initWithDynamicPlatform;
- (void)setDefaults;

@end

And in the .m file

#import "Platform.h"

@implementation Platform

- (instancetype)initWithImageNamed:(NSString *)name {
if (self == [super initWithImageNamed:name]) {
    NSLog(@"Initiated Platform");
}
return self;
}

- (instancetype)initWithDynamicPlatform {

if (self == [super initWithImageNamed:@"Platform2"]) {
    NSLog(@"Initiated Platform");
}

[self setDefaults];

return self;
}

- (void)setDefaults {

/**
 * Set the name
 */

self.name = @"Platform";

/**
 * Set the effect of gravity on the platform
 */

self.physicsBody.affectedByGravity = NO;
self.physicsBody.dynamic = NO;


 }

 @end

The problem is that from the SKScene file I cannot access the custom method.

- (void)loadDynamicPlatform {

SKSpriteNode *spritePlatform = [[Platform alloc] initWithDynamicPlatform];    

[spritePlatform setDefaults];

[self addChild:spritePlatform];
[self movePlatform:spritePlatform];

}

I get the error message

"/Users/****/Desktop/Apps/****/****/GameScene.m:142:21: No visible @interface for 'SKSpriteNode' declares the selector 'setDefaults'"

Any idea why I can not access this. I am sure I was setting it up correctly.

You have to declare a 'Platform' variable or cast the 'SKSpriteNode' to 'Platform': 

Platform *spritePlatform = [[Platform alloc] initWithDynamicPlatform];    

[spritePlatform setDefaults];
