What are the differences between XIB files and Storyboards when creating interfaces in iOS?

XIB files and Storyboard are two ways to create user interfaces in iOS, but they have several differences:

• XIB files are separate interface files for each screen or component. They are convenient for reusing individual views and allow working with the interface in parts.
• Storyboard is a single large file that contains multiple screens (View Controllers) and transitions (segues) between them. It is useful for visual design of navigation and connections between screens.

Main differences:

• Scalability: Storyboard can become cumbersome with a large number of screens, whereas XIB files are easier to maintain separately.
• Navigation: Storyboard allows visual configuration of transitions between screens, XIB does not.
• Collaboration: XIB files are more convenient for team work, as changes in one file do not conflict with others.

Example of usage:

// Loading UIView from XIB
let customView = Bundle.main.loadNibNamed("CustomView", owner: self, options: nil)?.first as? UIView

// Storyboard is used through ViewController identifiers
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "DetailViewController")
