UIButton Subclass And Initialization For Storyboard or Code - http://www.iosinsight.com/uibutton-subclass-and-initialization-for-storyboard-or-code/

AlignedImageButton.swift

import UIKit

class AlignedImageButton: UIButton {

	// Convenience initializer must delegate across not up
	// So we override init and call super.init to facilitate that
	override init(frame: CGRect) {
		super.init(frame: frame)
	}

	// For storyboard
	required public init?(coder aDecoder: NSCoder) {
		super.init(coder: aDecoder)
		// If button in storyboard is Custom, you'll need to set
		// title color for control states and optionally the font
		// I've set mine to System, so uncomment next three lines if Custom

		//self.setTitleColor(tintColor, for: .normal)
		//self.setTitleColor(tintColor.withAlphaComponent(0.3), for: .highlighted)
		//self.titleLabel?.font = UIFont.systemFont(ofSize: 15.0)
		configure()
	}

	// Convenience initializer calling across to our init that calls super.init
	// Setting up the image for UIControlState then calling common configure
	convenience init(frame: CGRect, image: UIImage) {
		self.init(frame: frame)
		self.setImage(image, for: UIControlState.normal)
		let imageHighlight = image.alpha(0.3)?.withRenderingMode(.alwaysTemplate)
		self.setImage(imageHighlight, for: UIControlState.highlighted)
		configure()
	}

	func configure() {
		// Just in case they aren't set in a Storyboard
		self.contentHorizontalAlignment = .left
		self.imageView?.contentMode = .scaleAspectFit

		guard let image = self.image(for: UIControlState.normal) else {
			return
		}

		// Inset the image based on left edge
		self.imageEdgeInsets = UIEdgeInsetsMake(0, self.bounds.size.width-image.size.width * 1.7, 0, 0)
		self.layer.borderWidth = 0.5
		self.layer.borderColor = UIColor.darkGray.cgColor
		// Inset top and bottom by 10
		self.contentEdgeInsets = UIEdgeInsetsMake(10,0,10,0)
	}

	// Configure button when bounds change since image inset has dependency on bounds
	override public var bounds: CGRect{
		didSet {
			configure()
		}
	}

}

// Credit to Peter Kreinz for this one (see link in tutorial)
extension UIImage {
	func alpha(_ value:CGFloat)->UIImage? {
		UIGraphicsBeginImageContextWithOptions(size, false, scale)
		draw(at: CGPoint.zero, blendMode: .normal, alpha: value)
		let newImage = UIGraphicsGetImageFromCurrentImageContext()
		UIGraphicsEndImageContext()
		return newImage
	}
}

Would like to move this to be a an extension of UIButton instead of a subclass of UIButton.
