I have array:

Code Block var imgs: [UIImage] = userDefaults.object(forKey: "myKey") as? [UIImage] ?? []

How I can save it?

Where do you want to save ?
To a file ?
Maybe the best is to save each image on an individual file, that will make retrieving, removing… simpler.

In that case:
You can convert images:

Code Block for img in imgs {
	let imageData = img.pngData()
    let fileName = // Create a file name for each image ; for instance from the name of the image
	fileManager.createFile(atPath: fileName, contents: imageData, attributes: nil)
}
