What is the difference between a .xib file and a .storyboard?

People also ask

What is Storyboard and XIB in Swift?

In simple words Storyboard is one single file for all the views or screens that in yours apps. It transitions one screen to another screen. It minimizes (reduces) the number of files in your apps. Storyboard can put the XIB files. Storyboard is universal; that means your apps can run both iPhone and iPad.

What is a Storyboard file?

What is an STORYBOARD file? Developer file introduced with Xcode 4.2, an IDE used for creating Mac OS X and iOS applications; stores screen layouts for an application as well as the ways the screens interact with each other through application events.

What is a XIB file?

XIBs are a newer, XML based format that is used for the UI at design time. When you compile your app, the XIB files are converted to binary NIB files for you, and those binary versions of the files are embedded into your app.

Is SwiftUI better than Storyboard?

Conclusion. After looking at the pros and cons of both Storyboard and SwiftUI, according to my opinion building app UI using storyboard is comparatively easier for a beginner, and has been there was a very long time, but there are some flaws with it and that flaws have been taken care of in Swift UI.


Apple introduced the concept of "storyboarding" in iOS5 SDK to simplify and better manage screens in your app. You can still use the .xib way of development.

Pre-storyboard, each UIViewController had an associated .xib with it. Storyboard achieves two things:

  1. .storyboard is essentially one single file for all your screens in the app and it shows the flow of the screens. You can add segues/transitions between screens, this way. So, this minimizes the boilerplate code required to manage multiple screens.

  2. Minimizes the overall number of files in an app.

You can avoid using Storyboard while creating a new project by leaving the "Use Storyboard" option unchecked.

Yes, you can still create a Window-based application for iOS 5. If you use the "empty project" template, you will see that a window is created for you in the app delegate. From there you can add XIB files as normal, or a new storyboard.

I'm assuming you mean "storyboards" rather than "timeline". Storyboards allow you to map out, visually, all of the views in your applications and how they interrelate. If you are just starting out with storyboards, there's an introduction to storyboards in the WWDC 2011 videos here. The 2011 Stanford iOS course on iTunes-U is also iOS 5-specific and covers storyboards and more.


A storyboard is like a canvas where you put all your .xib files. You no longer have any .xibs, you just have View Controllers directly on your canvas.


storyboard is a new feature available since the release of Xcode 4.2. It offers a complete new way for iOS developer to create and design user interface. Before the introduction of Storyboard, it’s especially hard for beginner to create navigation (and tab) interface. Every interface is stored in a separate xib file. On top of it, you have to write code to link all interfaces together and describe how the navigation works.

With Storyboards, all screens are stored in a single file. This gives you a conceptual overview of the visual representation for the app and shows you how the screens are connected. Xcode provides a built-in editor to layout the Storyboards. You can define the transition (known as segues) between various screens simply using point and click. This doesn’t mean you do not need to write code for the user interface. But Storyboards significantly reduce the amount of code you need to write.

XIB:

  1. Xib files are used with a single UIView.

2)It's very difficult to implement complex auto-layouts in xib.

3)It's utilizes more memory as compared to storyboard and quiet slow.

  1. It is compatible from iOS5 and onwards

  2. You can do localizations for different languages and countries using different XIBs .

  3. It's difficult to use same Xib to support multiple devices.

Storyboard

1)You can layout all your Scenes like View Controllers, Nav Controllers, TabBar Controllers, etc in a single storyboard.

2)You can use Auto Layout easily that defines mathematical relationships between elements defining their position and sizing.

3)Usually fast and allocates less memory.

4)It's not compatible prior to iOS 5 .

5)"Dynamic" and "Prototype" cells can be used easily.

6)Storyboards best to use for the apps with a small to medium amount of screens.
