Is it OK to use Apple's sample code in my app?

I'm writing my first iPhone app. I want to use some methods from the sample code downloaded from Apple website, such as the PhotoScroller sample project.

Is it OK to do so? (Sorry I have no knowledge of copyright nor copyleft.)

Thanks

Are all apps on the App Store legal?

Apps made available through the App Store are licensed, not sold, to you.

Does Apple track user data?

The Apple advertising platform does not track you, nor does it buy or share your personal information with other companies. Your Apple Pay transactions, Health app data, and HomeKit app data are not used by the Apple advertising platform to deliver ads.

Can you code on your iPhone?

Whether you're just learning to code or are an experienced developer, having the right coding app on your iPhone or iPad will help take your skills to the next level. You can find apps that teach you different languages or actual code editors that let you test your code in real-time.

Yes, it's absolutely acceptable to include sample code provided by Apple in your own iPhone application.
