Objective-C Basics / Introduction to Objective-C / From Structs to Objects

In the video Mr. Turner is coding in the header file (Sphere.h) he copies and pastes code from timeline 5:24 with blue highlight for the getter and setter methods but when we get to timeline 5:26 two seconds later where did the other code changes come from in the header file? timeline 5:24

#import <Foundation/ Foundation.h>
@interface Sphere : NSObject

VS timeline 5:26 

#import  “Sphere.h”
@implementation Sphere

Thanks for the help on really understanding Objective-C, Mark M.

(Edited for code block markdown)

First code block is from the header .h file, second code block is from the implementation .m file. So yes, two separate files.

Yes, second that. Wasted a lot of time trying to figure out what he did. Very frustrating. We start the lesson looking at the navigator bar on the left, but he seems to use some keyboard shortcut to switch files which appears near the top of the Xcode environment, while the Sphere.h file remains highlighted in the left navigation bar. Treehouse staff, can you please change this video to make it clearer.

I figured it out. The blue highlight for file shown in Navigator tree side does not show if he is in the .h or .m of Sphere in Xcode in the video. I thought he was in the header file for both timelines, but he transitioned to the .m at the timeline 5:26. I will make a note of this detail.
Thanks, Mark M.

I got hung up on this too - wasted a lot of time trying to figure it out. Needs to be more clear.
