A question on initialization about setting HOT 2 CLOSED

Ah yeah. So what happens is that when you make a Swift Package or framework, you need to implement your own init() method. The default memberwise struct init isn't available — see this Stack Overflow question.

Thankfully, Xcode has a "Generate Memberwise Initializer" feature that auto-generates the default memberwise initializer. I've been using this, which is why you see the same values duplicated.

from setting.

Yes, I'm aware of that Xcode generation feature, if we have the same values in the initializers, would it make sense to remove the default values of the properties and only keep the ones in the memberwise initializers?

For example, someone (I don't know who), might be tempted to update the property value directly instead of updating the default argument value from the initializer.

What I have in my mind is :

public struct PreviewConfiguration {
    public var icon: SettingIcon?
    public var indicator: String
    public var horizontalSpacing: CGFloat
    public var verticalPadding: CGFloat
    public var horizontalPadding: CGFloat

    public init(
        icon: SettingIcon? = nil,
        indicator: String = "chevron.forward",
        horizontalSpacing: CGFloat = CGFloat(12),
        verticalPadding: CGFloat = CGFloat(14),
        horizontalPadding: CGFloat = CGFloat(16)
    ) {
        self.icon = icon
        self.indicator = indicator
        self.horizontalSpacing = horizontalSpacing
        self.verticalPadding = verticalPadding
        self.horizontalPadding = horizontalPadding
    }
}

from setting.
