1. Core OS is located at the bottom of the iOS system architecture is the core operating system layer, which includes memory management, file system, power management and other operating system tasks. It can interact directly with hardware devices. As an app developer, you don't have to deal with this layer.

2. Core Services is the core service layer, through which you can access some services of iOS.

3. Media is the media layer, through which we can use all kinds of media files in the application, record audio and video, draw graphics, and make basic animation effects.

4. Cocoa Touch is the touchable layer, which provides a variety of useful frameworks for our application development, and most of them are related to the user interface. In essence, it is responsible for user touch interaction on iOS devices.

IOS is based on the UNIX kernel, and android is based on the Linux kernel. As two excellent mobile operating systems, iOS and android have something in common and differences. Share an android system architecture diagram below:
