Full tutorial available at sparrowcode.io.
Live Activity already enabled for upload with Xcode 14.1 RC.

Preparing Project
Add Widget target:
Or skip it if already supporting widgets. Next add to Info.plist key Supports Live Activities to true:
<key>NSSupportsLiveActivities</key>
<true/>
Define Model
Define model-data. There is dynamic and static properties. Dynamic can be updated in time and make changes in UI. Static using only for launch Live Activity.
struct ActivityAttribute: ActivityAttributes {
public struct ContentState: Codable, Hashable {
// Dynamic properties.
// Can be updated when Live Actvity created.
var dynamicStringValue: String
var dynamicIntValue: Int
var dynamicBoolValue: Bool
}
// Static properties.
// Used only when make live actvity.
// Can't update it later.
var staticStringValue: String
var staticIntValue: Int
var staticBoolValue: Bool
}Add UI
Define Widget wrapper:
struct LiveActivityWidget: Widget {
let kind: String = "LiveActivityWidget"
var body: some WidgetConfiguration {
ActivityConfiguration(for: ActivityAttribute.self) { context in
// UI for lock screen
} dynamicIsland: { context in
// UI for Dynamic Island
}
}
}
