VideoEditor SDK supports adding custom fonts from the app bundle. In this example, we add the font Raleway.

Creating `Font` objects#

We create a URL pointing to the font's location in the app bundle and pass it to the Font constructor. A Font object is a simple collection of the metadata of a font, the fontName, the displayName and the url for non system fonts. We can also create another system font using only the fontName.

Add fonts to asset catalog#

In order to add the new fonts to our asset catalog, we first add the default items and then append our fonts to the fonts array.


import UIKit
import VideoEditorSDK

class VideoAddFontsFromAppBundleSwift: Example, VideoEditViewControllerDelegate {
  override func invokeExample() {
    // Create a `Video` from a URL to a video in the app bundle.
    let video = Video(url: Bundle.main.url(forResource: "Skater", withExtension: "mp4")!)

    // Create a reference to a custom font.
    let fontURL = Bundle.main.url(forResource: "custom_font_raleway_regular", withExtension: "ttf")
    let customFont = Font(url: fontURL!, displayName: "Raleway", fontName: "custom_font_raleway_regular", identifier: "custom_font_raleway_regular")

    // Create a reference to a system font.
    let systemFont = Font(displayName: "Helvetica", fontName: "Helvetica", identifier: "system_font_helvetica")

    // Create a `Configuration` object.
    let configuration = Configuration { builder in
      // In this example we are using the default assets for the asset catalog as a base.
      // However, you can also create an empty catalog as well which only contains your
      // custom assets.
      let assetCatalog = AssetCatalog.defaultItems

      // Add the custom fonts to the asset catalog.
      assetCatalog.fonts.append(contentsOf: [customFont, systemFont])

      // Use the new asset catalog for the configuration.
      builder.assetCatalog = assetCatalog
    }

    // Create and present the video editor. Make this class the delegate of it to handle export and cancelation.
    let videoEditViewController = VideoEditViewController(videoAsset: video, configuration: configuration)
    videoEditViewController.delegate = self
    videoEditViewController.modalPresentationStyle = .fullScreen
    presentingViewController?.present(videoEditViewController, animated: true, completion: nil)
  }

  // MARK: - VideoEditViewControllerDelegate

  func videoEditViewControllerShouldStart(_ videoEditViewController: VideoEditViewController, task: VideoEditorTask) -> Bool {
    // Implementing this method is optional. You can perform additional validation and interrupt the process by returning `false`.
    true
  }

  func videoEditViewControllerDidFinish(_ videoEditViewController: VideoEditViewController, result: VideoEditorResult) {
    // The user exported a new video successfully and the newly generated video is located at `result.output.url`. Dismissing the editor.
    presentingViewController?.dismiss(animated: true, completion: nil)
  }

  func videoEditViewControllerDidFail(_ videoEditViewController: VideoEditViewController, error: VideoEditorError) {
    // There was an error generating the video.
    print(error.localizedDescription)
    // Dismissing the editor.
    presentingViewController?.dismiss(animated: true, completion: nil)
  }

  func videoEditViewControllerDidCancel(_ videoEditViewController: VideoEditViewController) {
    // The user tapped on the cancel button within the editor. Dismissing the editor.
    presentingViewController?.dismiss(animated: true, completion: nil)
  }
}
