How to find the size of any object in iOS?

Question

I was optimizing my app and wanted to know that how much is the size of the object, so that I can also show it in log.

suppose I have

NSDictionary *t         


        

Answer 1

In objective- C:

NSString *sampleString = @"iOS Programming";
 NSLog(@"size of object: %zd", malloc_size((__bridge const void *)(sampleString)));

You need to include:
#import

In Swift:

var name: String = "Hello World!"

sizeofValue(name)

var someValue: Double = 10.5

sizeofValue(someValue)
