iOS gives structures that characterize specific arrangements of usefulness from gaming and media to security and data administration which you can integrate into your application. UIKit system is utilized to design your application's UI and the Foundation structure to consolidate regular data structures and conduct into your code. These are two of the most widely recognized systems utilized in of iOS application development.

User Interface
1. UIKit – Its classes permit you to make a touch-based UI. Since all iOS applications depend on UIKit, you can't send an application without this system. It gives the foundation for attracting to the screen, dealing with occasions and making basic UI components. UIKit additionally masterminds a complex application by sorting out the substance that is appeared on the screen.

2. Core Graphics – It is a low level, C based system. It is the workhorse for taking care of brilliant vector designs, way based illustration, changes, pictures, information administration and then some.
The least demanding and most proficient approach to make designs in iOS is to utilize prerendered pictures with the standard perspectives and controls of the UIKit structure. Since UIKit is a more elevated amount system which likewise gives classes to custom illustration including ways, hues, designs, slopes, pictures, content, and changes?

3. Core Animation – Its interfaces are a piece of the Quartz Core structure. To make more elevated amount activities and visual impacts utilize Core Animation. UIKit gives liveliness that is based on the Core Animation innovation.
In the event that you require propelled movements more distant than the abilities of UIKit, utilize Core Animation specifically. You can make a pecking order of layer questions that you control, turn, scale, change. Center Animation's natural view-like deliberation gives you a chance to can make dynamic UIs without using low-level designs APIs, for example, OpenGL ES.

Games
1. GameKit – This system gives leaderboards, accomplishments and different highlights to add to your iOS diversion.

2. SpriteKit – This system gives designs support to quickening self-assertive finished pictures or sprites. Notwithstanding being an illustrations motor, it additionally contains material science support to breathe life into objects. It is a decent choice for amusements and different applications that need complex movement chains.

3. OpenGL ES – It is a low-level system that backings equipment quickened 2D and 3D drawing. Apple's usage of the OpenGL ES standard works personally with the gadget equipment to give high casing rates for full screen, diversion style applications. Since it is a low-level equipment centered API; it has a lofty expectation to absorb information and a noteworthy impact on the general outline of your application.

4. Game Controller – This system makes it easy to seek controllers associated with a Mac or iOS gadget. At the point when a controller is opened on your gadget, your amusement looks at control contributions as a component of its ordinary gameplay. These controllers give new courses for players to control your amusement. Apple has composed particulars for equipment controllers to guarantee that all controllers have reliable arrangements of control components that the two players and diversion planners can depend on.

Information
1. Core Data – It deals with an application's information show. Utilize it to make show objects which are known as overseen objects. You oversee connections between those articles and roll out improvements to the information through the system. It takes advantage of the implicit SQLite innovation to spare and oversee information skillfully.

2. Establishment – This system characterizes an arrangement of critical base classes. In addition to other things, this structure contains classes speaking to essential information writes like as strings and numbers and accumulation classes for sparing different articles.
