Dash Snippet for SwiftUI Environments & Modifiers

environment.swift

struct __ValueType__ {
}

struct __ValueType__Key: EnvironmentKey {
    static var defaultValue = __ValueType__()
}

extension EnvironmentValues {
    var __KeyName__: __ValueType__ {
        get {
            self[__ValueType__Key.self]
        }
        set {
            self[__ValueType__Key.self] = newValue
        }
    }
}

struct __ValueType__Modifier: ViewModifier {
    let value: __ValueType__
    func body(content: Content) -> some View {
        content.environment(\.__KeyName__, value)
    }
}

extension View {
    func __KeyName__(value: __ValueType__) -> some View {
        self.modifier(__ValueType__Modifier(value: value))
    }
}

And if you prefer Xcode style snippets:

struct <#ValueType#> {
}

struct <#ValueType#>Key: EnvironmentKey {
    static var defaultValue = <#ValueType#>()
}

extension EnvironmentValues {
    var <#KeyName#>: <#ValueType#> {
        get {
            self[<#ValueType#>Key.self]
        }
        set {
            self[<#ValueType#>Key.self] = newValue
        }
    }
}

struct <#ValueType#>Modifier: ViewModifier {
    let value: <#ValueType#>
    func body(content: Content) -> some View {
        content.environment(\.<#KeyName#>, value)
    }
}

extension View {
    func <#KeyName#>(value: <#ValueType#>) -> some View {
        self.modifier(<#ValueType#>Modifier(value: value))
    }
}
