Question 1

How do I change SVG colors at runtime with SwiftSVG?

Accepted Answer

Use the completion block in UIView or CALayer initializers to modify the SVGLayer's fillColor property, as shown in examples where pizza and hammock SVGs are recolored dynamically.

Question 2

Does SwiftSVG support SVG gradients?

Accepted Answer

No, gradients are not currently supported, though the README mentions they are high on the list of features to add next. For now, it's limited to solid-color elements.

Question 3

SwiftSVG vs SVGKit: which is better for iOS?

Accepted Answer

SwiftSVG is better for performance and simplicity with flat icons and runtime theming, while SVGKit offers more complete SVG spec support, including gradients and text, at the cost of potential overhead.

Question 4

How to use SwiftSVG with Interface Builder?

Accepted Answer

Use the SVGView subclass, which is IBInspectable; add a view in your storyboard, set the class to SVGView, and specify the SVG file name in the SVGName property, as illustrated in the documentation.

Question 5

Can SwiftSVG parse SVGs from a remote URL?

Accepted Answer

Yes, you can use the UIView(SVGURL:) initializer to load and parse SVGs from a URL asynchronously, with examples like the hammock SVG fetched from openclipart.org.

Question 6

What are the breaking changes in SwiftSVG 2.0?

Accepted Answer

Version 2.0 deprecated String extensions and the ability to parse single path strings from a URL, so projects using 1.x may need code updates, as noted in the install section.
