adding objc_boxable to CoreGraphics structs

main.m

@import Foundation;
@import CoreGraphics;

typedef struct __attribute__((objc_boxable)) CGPoint CGPoint;
typedef struct __attribute__((objc_boxable)) CGSize CGSize;
typedef struct __attribute__((objc_boxable)) CGRect CGRect;
typedef struct __attribute__((objc_boxable)) CGVector CGVector;

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        CGRect rect = CGRectMake(0, 0, 100, 50);
        NSValue *boxedRect = @(rect);
        NSLog(@"boxed: %@", boxedRect);
    }
    return 0;
}
