The lower layers of its architecture deliver basic services, while the higher layers provide more sophisticated graphics and user interfaces.

Apple’s system interfaces are packed in frames, with each frame consisting of a programming model library, related pictures, header files, and helper apps. Each layer has its own set of frameworks that help the developer create apps.

Here are the different layers in the iOS architecture:

  • Core OS
  • Core Services – Cloudkit framework, Core foundation framework, Core Data Framework, Address Book Framework, Core Motion Framework, Healthkit Framework, Core Location Framework

The cost of iOS app development depends on the number of hours spent developing that app, the platform, and the stipulated time frame.

Here are two important factors that affect the cost of an iOS app:

1. App Size

The larger the app, the higher the cost of developing it. Smaller apps are easy to make and take less time, whereas larger apps have more screens and take more time to be developed.

A small app takes approximately 2-4 months to be completed and costs around $8,000-25,000. A medium-sized app will be ready in around 4-8 months, costing nearly $25,000-50,000. A complex app will take over eight months to develop and typically cost more than $50,000.

2. Complexity Of Features

The more features you add, the more complex the app will be and the more it will cost to be made.
