UIView Extension addGradient(colors: locations: direction:)

[Andy0570]

Describe the bug
Unable to pass direction parameter when adding a gradient to a view via extension method addGradient(colors: locations: direction:)

To Reproduce
Steps to reproduce the behavior:
In Xcode project, add gradient to UIView instance:

let colors = [UIColor(hexString: "#ffede7").require(), UIColor(hexString: "fffae5").require()]
addGradient(colors: colors, direction: GradientDirection.rightToLeft)

Xcode show Error:

'rightToLeft' is inaccessible due to 'internal' protection level

Expected behavior

Screenshots

Desktop (please complete the following information):

• OS: Mac OS
• Version: 13.5.2

Smartphone (please complete the following information):

• Device: iPhone 11 Pro Max
• OS: iOS17.0.3

Additional context
SwifterSwift 6.0.0
Xcode 15.0

Suggestions

Access control needs to be added to GradientDirection Struct in UIView extension, such as:

/// SwifterSwift: Add gradient directions
struct GradientDirection {
    public static let topToBottom = GradientDirection(startPoint: CGPoint(x: 0.5, y: 0.0),
                                               endPoint: CGPoint(x: 0.5, y: 1.0))
    public static let bottomToTop = GradientDirection(startPoint: CGPoint(x: 0.5, y: 1.0),
                                               endPoint: CGPoint(x: 0.5, y: 0.0))
    public static let leftToRight = GradientDirection(startPoint: CGPoint(x: 0.0, y: 0.5),
                                               endPoint: CGPoint(x: 1.0, y: 0.5))
    public static let rightToLeft = GradientDirection(startPoint: CGPoint(x: 1.0, y: 0.5),
                                               endPoint: CGPoint(x: 0.0, y: 0.5))

    let startPoint: CGPoint
    let endPoint: CGPoint

    public init(startPoint: CGPoint, endPoint: CGPoint) {
        self.startPoint = startPoint
        self.endPoint = endPoint
    }
}

Hello,
Is any help needed on this bug. I read through and I am interested in working on it.
Thanks!

@lauren-g-miller sorry I'd already fixed it, although it would've been a good one to offer as a first issue. Have a look at the other ones, maybe for example providing support for visionOS?
