Other information

For now, the base branch is the UIKit VitaminButton icon alone branch, will change to develop once validated and merged

[daniel-dumortier]

I decided to commit an intermediate solution for the problem of reusing VitaminButtonIconType :

• I created an specific IconType enum for swiftUI, that can still have an UIImage associated value, but a Image.TemplateRenderingMode (and not a UIImage.RenderingMode anymore)
• this IconType has an internal computed property of type VitaminButtonIconType

With this approach, I think we combine two advantages :

• the associated values of IconType are more "swiftUI" (even if it still uses UIImage, but after all, Vitamix also deals with UIImage)
• all the logic and computed properties of VitaminButtonIconType can be reused for swiftUI

Any feedbacks on this approach (and if it is better than the previous) are welcome ;)
