Guidelines: Customization

Components from VComponents are not meant to be customized the same way you would customize atomic SwiftUI components.

Rather than directly modifying them using ViewModifierss, you are supposed to pass an UI model as a parameter to the initializers. All components have default UI models and passing them to initializers is not required. Furthermore, all properties within the UI models have their own default values.

For instance, you can change the foreground color of a VPlainButton by changing the values.

Not Preferred:

var body: some View {
    VPlainButton(
        action: doSomething,
        title: "Lorem Ipsum"
    )
    .foregroundStyle(.primary)
}

Preferred:

let uiModel: VPlainButtonUIModel = {
    var UIModel: VPlainButtonUIModel = .init()
    
    uiModel.titleTextColors = VPlainButtonUIModel.StateColors(
        enabled: Color.primary,
        pressed: Color.secondary,
        disabled: Color.secondary
    )
    
    return uiModel
}()

var body: some View {
    VPlainButton(
        uiModel: uiModel,
        action: doSomething,
        title: "Lorem Ipsum"
    )
}

Alternately, you can create static instances of UI models for reusability.

extension VPlainButtonUIModel {
    static let someUIModel: Self = {
        var uiModel: Self = .init()
        
        uiModel.titleTextColors = StateColors(
            enabled: Color.primary,
            pressed: Color.secondary,
            disabled: Color.secondary
        )
        
        return uiModel
    }()
}

var body: some View {
    VPlainButton(
        uiModel: .someUIModel,
        action: doSomething,
        title: "Lorem Ipsum"
    )
}

Frequently, you will discover pre-configured static factory-initialized UI models associated with each component. It's recommended to investigate UI model files before defining them yourself.

var body: some View {
    VWrappingMarquee(
        uiModel: .insettedGradient,
        content: {
            HStack(content: {
                Image(systemName: "swift")
                Text("Lorem ipsum dolor sit amet, consectetur adipiscing elit.")
            })
            .drawingGroup() // For `Image`
        }
    )
}

Guidelines: Animations

VComponents associates animations directly with the components and their UI models, rather than with the external state.

@State private var isOn: Bool = false

var body: some View {
    VStack(content: {
        VToggle(isOn: $isOn)
        
        VPlainButton(
            action: { isOn.toggle() },
            title: "Toggle"
        )
    })
}

By default, the VToggle uses an easeIn animation with a duration of 0.1 to handle state changes. This applies uniformly to both touch interactions, as well as any external modifications of the state. So, to modify state with a different animation, you'll need to provide a custom UI model.

@State private var isOn: Bool = false

var body: some View {
    VStack(content: {
        VToggle(
            uiModel: {
                var uiModel: VToggleUIModel = .init()
                uiModel.stateChangeAnimation = .easeIn(duration: 1)
                return uiModel
            }(),
            isOn: $isOn
        )
        
        VPlainButton(
            action: { isOn.toggle() },
            title: "Toggle"
        )
    })
}

There are two available options for completely cancelling animations.

The first is to set stateChangeAnimation to nil. While this does not completely remove animation, it essentially applies a nil animation.

The second is to set appliesStateChangeAnimation to false. This option ensures that the stateChangeAnimation is not applied at all, thus effectively removing any animation tied to state changes, even nil.

@State private var isOn: Bool = false

var body: some View {
    VStack(content: {
        VToggle(
            uiModel: {
                var uiModel: VToggleUIModel = .init()
                uiModel.stateChangeAnimation = nil
                return uiModel
            }(),
            isOn: $isOn
        )
        
        VPlainButton(
            action: { isOn.toggle() },
            title: "Toggle"
        )
    })
}

or

@State private var isOn: Bool = false

var body: some View {
    VStack(content: {
        VToggle(
            uiModel: {
                var uiModel: VToggleUIModel = .init()
                uiModel.appliesStateChangeAnimation = false
                return uiModel
            }(),
            isOn: $isOn
        )
        
        VPlainButton(
            action: { isOn.toggle() },
            title: "Toggle"
        )
    })
}

In certain scenarios, the distinction between these two can be substantial. For example, we could set the appliesStateChangeAnimation flag to false and subsequently mutate the state with an external animation.

@State private var isOn: Bool = false

var body: some View {
    VStack(content: {
        VToggle(
            uiModel: {
                var uiModel: VToggleUIModel = .init()
                uiModel.appliesStateChangeAnimation = false
                return uiModel
            }(),
            isOn: $isOn
        )
        
        VPlainButton(
            action: { 
                withAnimation(.easeInOut(duration: 1), {
                    isOn.toggle()
                })
            },
            title: "Toggle"
        )
    })
}
