This pod aims to simplify the process of building custom IBDesignables by
reducing boilerplate and hiding the ugly interface builder details from what
should be concise, and reusable subclasses of UIView.

CI Status


To run the example project, clone the repo, and run pod install from the
Example directory first.

XibView is available through CocoaPods. To install
it, add the following line to your Podfile:

pod "XibView"


The basic workflow for creating a custom IBDesignable looks like this.

  1. start with stubbing your UIView subclass
import XibView

@IBDesignable class DummyView: XibView {


you’ll notice that instead of subclassing UIView, we have subclassed XibView
instead. What this does is associate this class directly with a xib file of the
same name. Don’t worry, XibView is a subclass of UIView.

  • dont forget the @IBDesignable flag. without it, the interface builder
    wont know that this is a view to build.
  1. Create the xib file

Next create the .xib file that you will design your custom view in, it’s
important that the xib filename match the class that it will be owned by. This
is how the XibView machinery automatically finds its xib file based on the
subclass name. In our example case the file would be called DummyView.xib

  1. Set the owner of the nib file to the class you stubbed.

  • the view inside the xib should not be subclassed by the custom class
  1. Set up the view dimensions

Select View

  1. Design your view


  1. Hookup IBOutlets, IBActions, write IBInspectables, etc.
import XibView

/// an example of the XibView subclassing pattern
@IBDesignable class DummyView: XibView {

    /// some segmented control
    @IBOutlet weak var segmentedControl: UISegmentedControl!

    /// some button
    @IBOutlet weak var button: UIButton!

    /// the background color of some button, can be changed
    /// in the interface builder
    @IBInspectable var buttonBackgroundColor: UIColor? {
        get {
            return button.backgroundColor
        set {
            button.backgroundColor = newValue

    /// the top switch
    @IBOutlet weak var switchTop: UISwitch!

    /// the bottom switch
    @IBOutlet weak var switchBottom: UISwitch!

  1. Use your custom view in another view or storyboard or whatever!

Using View


The way CocoaPods handles resource bundles for views is a little funky compared
to the way it’s done in a single target application. PodXibView is here to
fix that problem for all the UI building CocoaHeads out there. All the steps
are the same, plus the extra final steps below.

  1. Determine the name of the resource bundle that your IBDesignable subclasses
    xib is located in.

this information can be found in your podspec and usually looks something like

s.resource_bundles = {
   'SomeBundleName' => ['YourCocoaPodProjectDir/Classes/**/*.{storyboard,xib}']
  1. Conform your subclass to the PodXibViewSubclassing protocol and implement
    the required function returning the name of the bundle you got in step 7.

    • make sure the access control level for the class is either public or
      open if this class should be accessible when users install the pod
    • check that properties also have the appropriate access control level,
      or else they wont be available outside of the context of your
      framework. Again public, or open.

Naturally Apple has some pretty thorough documenation surrounding access
control. If you’re new to frameworks, or wonder whether public or open is more
applicable for your use case read this (should probably read it if you haven’t

Apple Access Control Docs

import XibView

/// An example IBDesignable for use within a published cocoapod
@IBDesignable public class DummyView: PodXibView, PodXibViewSubclassing {

    /// Return the name of the bundle that the xib for this class
    /// is located in.
    /// - returns: the name of the bundle that this view lives in
    func getBundleName() -> String {
        return "SomeBundleName"
  1. Use your view in another project by installing it with CocoaPods!
