        var url: NSURL = NSURL.fileURLWithPath(path)  //Creating a URL which points towards our path

iOS Swift Add SVG Image to button like Android

UPD: Also see this UseYourLoaf blog post

Just found on Erica Sadun blog post that on iOS 11 you could use Vector Assets.

What "Vector Assets" mean:

If you click that box, the vector data will be shipped with your
application. Which, on the one hand, makes your application a little
bit larger, because the vector data takes up some space. But on the
other hand, will give you the opportunity to scale these images, which
might be useful in a number of different situations. So, one is, if
you know that this particular image is going to be used at multiple
sizes. But that might be less obvious. So, one case is a symbolic
glyph that should resize with dynamic type. Since we're thinking about
dynamic type, you should also be thinking about having glyphs that are
appearing next to type resize appropriately. Another case that's
really not obvious, is tab bar images.
... there's a really great accessibility feature that we strongly
recommend supporting, that allows for user that have turned their
dynamic type size up. ... So, we really recommend doing that to increase the usability of your app across all users

How to use:

1. Convert your SVG file into PDF, e.g. on ZamZar.com
2. Add your pdf to Assets.xcassets
   
   
   • Click "Preserve Vector Data" for the imported pdf.
3. Create UIImageView in your UIViewController and assign pdf file like UIImage.

or Asset Catalog Creator available in the Mac App Store will do steps 1 and 2 with a simple drag and drop.

iOS < 11

There is no native way to use SVG image.

Take a look at Macaw

Import framework via Cocoapod

pod "Macaw", "0.8.2"

Check their example project: this is how you render tiger.svg (located in project directory, not in an Assets.xcassets file)

import UIKit
import Macaw

class SVGExampleView: MacawView {

    required init?(coder aDecoder: NSCoder) {
        super.init(node: SVGParser.parse(path: "tiger"), coder: aDecoder)
    }

}

There are some other third-party libraries of course:

• SwiftSVG
• Snowflake
• SVGKit Objective-C framework

Swift SVG Fil Color to SVGImage

Wish Swift adds this feature in their next release

After a nightmare, I came up with this solution for

Using SVG in Swift which fits automatically for the View and can add fill colors to it in just one line of code

This is for all who don't wish to struggle like me

|*| Usage :

let svgImgVar = getSvgImgFnc("svgImjFileName", ClrVar : ClrVar)

// Can use this Image anywhere in your code

|*| Steps :

I used the simple SwiftSVG library for getting UIView from SVG File

|*| Install SwiftSVG Library

1) Use pod to install :

// For Swift 3

pod 'SwiftSVG'

// For Swift 2.3

pod 'SwiftSVG', '1.1.5'

2) Add framework

Goto AppSettings

-> General Tab

-> Scroll down to Linked Frameworks and Libraries

-> Click on plus icon

-> Select SVG.framework

3) Add below code anywhere in your project

func getSvgImgFnc(svgImjFileNameVar: String, ClrVar: UIColor) -> UIImage
{
    let svgURL = NSBundle.mainBundle().URLForResource(svgImjFileNameVar, withExtension: "svg")
    let svgVyuVar = UIView(SVGURL: svgURL!)

    /* The width, height and viewPort are set to 100 

        
            viewBox="0 0 100 100">

        So we need to set UIView Rect also same
    */

    svgVyuVar.frame = CGRect(x: 0, y: 0, width: 100, height: 100)
    for svgVyuLyrIdx in svgVyuVar.layer.sublayers!
    {
        for subSvgVyuLyrIdx in svgVyuLyrIdx.sublayers!
        {
            if(subSvgVyuLyrIdx.isKindOfClass(CAShapeLayer))
            {
                let SvgShpLyrIdx = subSvgVyuLyrIdx as? CAShapeLayer
                SvgShpLyrIdx!.fillColor = ClrVar.CGColor
            }
        }
    }
    return svgVyuVar.getImgFromVyuFnc()
}

extension UIView
{
    func getImgFromVyuFnc() -> UIImage
    {
        UIGraphicsBeginImageContext(self.frame.size)

        self.layer.renderInContext(UIGraphicsGetCurrentContext()!)
        let image = UIGraphicsGetImageFromCurrentImageContext()

        UIGraphicsEndImageContext()
        return image!
    }
}
