While a number of these changes were under the hood they do +require changes to how you have previously used Vexil and include several source-breaking +changes. + +## Overview + +Originally, in order to avoid significant amounts of boilerplate, Vexil made heavy use of +reflection (with [Mirror](https://developer.apple.com/documentation/Swift/Mirror) to interact +with the flag hierarchy. While the reflection information was cached it was still a heavy +performance penalty for larger flag hierarchies. There was also a large amount of value type +copying going on, resulting in a larger than desired memory footprint. + +In Vexil 3, we make use of [Swift Macros](https://docs.swift.org/swift-book/documentation/the-swift-programming-language/macros/) +to generate conformance to the [Visitor Pattern](https://en.wikipedia.org/wiki/Visitor_pattern). And like +SwiftUI, Vexil 3 creates structs as required instead of copying them around everywhere, reducing overall +memory consumption. + +## Minimum Version + +Vexil 3 has been rewritten from the ground up to make heavy use of Swift Macros and Structured +Concurrency. As such as has the following minimum supported requirements: + +### Development Environment + +- Swift 5.10 +- Xcode 15.4+ + +### Operating Systems + +- iOS 15.0 (previously 13.0) +- macOS 12.0 (previously 10.15) +- tvOS 15.0 (previously 13.0) +- watchOS 8.0 (previously 6.0) +- visionOS 1.0 +- Linux variants supporting Swift 5.10+ + +## Flag Declarations + +The largest change is to how flag hierarchies are declared, consider the following example: + +```swift +// Vexil 2 +struct MyFlags: FlagContainer { + + @Flag(default: false, description: "Test flag that does something magical") + var testFlag: Bool + + @FlagGroup(description: "Some nested flags") + var nested: NestedFlags + +} + +// Vexil 3 +@FlagContainer +struct MyFlags { + + @Flag(default: false, description: "Test flag that does something magical") + var testFlag: Bool + + @FlagGroup(description: "Some nested flags") + var nested: NestedFlags + +} +``` + +As you can see, the main change is moving `FlagContainer` from a protocol to a macro. +There are also minor changes to `@Flag` and `@FlagGroup`, which were rewritten as macros +from property wrappers. + +### Flag Containers + +The most visible change is the ``FlagContainer(generateEquatable:)`` macro. The `FlagContainer` +protocol is still in use, but it has different requirements now. When adopting Vexil 3 you will +see the following warning: + +```swift +struct MyFlags: FlagContainer { // Type 'MyFlags' does not conform to protocol 'FlagContainer' + + // Flags here + + // Vexil 2 FlagContainer initialiser + init() {} + +} +``` + +To migrate this container to Vexil 3, remove the empty initialiser and attach the `@FlagContainer` macro: + +```swift +@FlagContainer +struct MyFlags { + + // Flags here + +} +``` + +The macro will attach and generate the ``FlagContainer`` protocol conformance and its visitor pattern +requirements. + +### Flag Groups + +In Vexil 2, `@FlagGroup` was a property wrapper with the following initialiser: + +```swift +FlagContainer.init( + name: String? = nil, + codingKeyStrategy: CodingKeyStrategy = .default, + description: FlagInfo, + display: Display = .navigation +) +``` + +Under Vexil 3, this is now a macro: + +```swift +public macro FlagGroup( + name: StaticString? = nil, + keyStrategy: VexilConfiguration.GroupKeyStrategy = .default, + description: StaticString, + display: VexilDisplayOption = .navigation +) +``` + +As you can see the changes here purely for simplification: `codingKeyStrategy` +was shortened to `keyStrategy`, and the description and display parameters +were refined. Previously, to hide a `@FlagGroup` from Vexillographer you +could set your description to `.hidden`; now you pass `.hidden` to display: + +```swift +// Vexil 2 +@FlagGroup(description: .hidden) +var nested: NestedFlags + +// Vexil 3 +@FlagGroup(description: "Nested flags", display: .hidden) +var nested: NestedFlags +``` + +### Flags + +Much like Flag Groups, the `@Flag` property wrapper was replaced with the +``Flag(name:keyStrategy:default:description:)`` macro, with simplified parameters: + +```swift +// Vexil 2 + +@Flag(default: false, description: "Flag that enables magic") +var magic: Bool + +@Flag(description: "Flag that enables magic") +var magic = false + +// Vexil 3 + +@Flag(default: false, description: "Flag that enables magic") +var magic: Bool + +@Flag("Flag that enables magic") +var magic = false +``` + +You can see the full breadth of changes by comparing the signatures. Under Vexil 2 +there are two initialisers of the property wrapper: + +```swift +// Explicit default: parameter +init( + name: String? = nil, + codingKeyStrategy: CodingKeyStrategy = .default, + default initialValue: Value, + description: FlagInfo +) + +// Sets default via property initialiser +init( + wrappedValue: Value, + name: String? = nil, + codingKeyStrategy: CodingKeyStrategy = .default, + description: FlagInfo +) +``` + +Both approaches are available via the `@Flag` macro: + +```swift +/// Explicit default parameter +macro Flag( + name: StaticString? = nil, + keyStrategy: VexilConfiguration.FlagKeyStrategy = .default, + default initialValue: Value, + description: StaticString, + display: FlagDisplayOption = .default +) + +/// Sets default via property initialiser +macro Flag( + name: StaticString? = nil, + keyStrategy: VexilConfiguration.FlagKeyStrategy = .default, + description: StaticString, + display: FlagDisplayOption = .default +) + +/// There is also an even more minimal macro +macro Flag(_ description: StaticString) +``` + +Same as with the `FlagGroup`, the `codingKeyStrategy` parameter has been shortened +to `keyStrategy`, and the ability to hide flags has been moved to the `display` property. + +## Flag Pole Observation + +Under Vexil 2, every time a `FlagValueSource` reported a flag value change, we would +take a snapshot of the `FlagPole` and refresh all of the values that changed, before +publishing that snapshot. This is inefficient. + +```swift +// Vexil 2 + +// Subscribe to changes of the whole flag pole +flagPole.publisher + .sink { snapshot in + // Do something + } +``` + +Under Vexil 3, we offer a few different publishers depending on what you're looking to do. + +```swift +// Takes and publishes a snapshot of flag values at the time any of our sources changes. +// This is the same behaviour as Vexil 2 +flagPole.snapshotPublisher + .sink { snapshot in + // Do something + } + +// Publishes a new instance of the `RootGroup` every time any of our sources changes. +// Unlike a snapshot, accessing values on the `RootGroup` is done lazily as required. +flagPole.flagPublisher + .sink { flags in + // Do something + } + +// Publishes a raw stream of `FlagChange`s that you can react to. +flagPole.changePublisher + .sink { changes in + // Do something with the list of flags that have changed + } +``` + +These are also available as `AsyncSequence`s. + +```swift +for await snapshot in flagPole.snapshots { + // Do something with each snapshot of the flag pole +} + +for await flags in flagPole.flags { + // Do something with each RootGroup +} + +for await change in flagPole.changes { + // Do something with each FlagChange +} +``` + +## Flag Observation + +Under Vexil 2 you could subscribe to a single flag via the projected property (ie `$someFlag.publisher`). +This would wrap the `FlagPole`'s publisher so was equally as inefficient. + +```swift +// Subscribe to changes of a single flag +flagPole.$someFlag.publisher + .sink { value in + // Do something + } +``` + +Under Vexil 3 you can access the same functionality by subscribing to the generated peer property directly. +This subscribes to the list of changes under the hood so it can defer fetching and comparing values until +it knows it has changed.
