Walkthrough

The changes involve the addition of the @MainActor attribute to the QRScannerViewDelegate protocol in the QRScannerViewDelegate.swift file. This modification indicates that all methods defined within the protocol are to be executed on the main actor, ensuring that UI updates and interactions occur on the main thread. Additionally, the UBPushManager class in UBPushManager.swift has been updated to enhance concurrency handling for push notification permissions and callbacks, including the use of @Sendable attributes and Task { @MainActor in ... } for executing UI-related code.

Changes

File Path Change Summary
Sources/UBQRScanner/QRScannerViewDelegate.swift Added @MainActor attribute to the QRScannerViewDelegate protocol.
Sources/UBPush/UBPushManager.swift Updated PermissionRequestCallback to @Sendable, modified closures for push notification handling to use @Sendable, and replaced DispatchQueue.main.async with Task { @MainActor in ... } for main thread execution.

Poem

🐇 Hopping through code, a new change we see,
With @MainActor, how happy we'll be!

In the world of QR, our worries are shed.
So let’s celebrate, with joy in our heart,
For every small change is a brand new start! 🌟

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

175-178: Ensure UI updates occur on the main actor

Wrapping the registration code within Task { @MainActor in ... } ensures that UI-related operations are executed on the main actor, which is necessary for thread safety when interacting with UI elements.

Note: Line 178 exceeds the maximum line length of 120 characters as indicated by SwiftLint.

Consider refactoring to comply with the line length guideline:

 Task { @MainActor in
-    UNUserNotificationCenter.current().setNotificationCategories(self.pushHandler.notificationCategories)
+    UNUserNotificationCenter.current()
+        .setNotificationCategories(self.pushHandler.notificationCategories)
     UIApplication.shared.registerForRemoteNotifications()
 }

🪛 SwiftLint

[Warning] 178-178: Line should be 120 characters or less; currently it has 121 characters

(line_length)


Line range hint 285-293: Simplify openSettingsFor method by eliminating redundant conditionals

The userNotificationCenter(_:openSettingsFor:) method can be simplified by directly passing the optional notification to pushHandler.openInAppSettings(_:), eliminating the need for the conditional check.

Consider refactoring the method:

 public nonisolated func userNotificationCenter(_ center: UNUserNotificationCenter, openSettingsFor notification: UNNotification?) {
-    if let notification {
-        Task { @MainActor in
-            pushHandler.openInAppSettings(notification)
-        }
-    } else {
-        Task { @MainActor in
-            pushHandler.openInAppSettings(nil)
-        }
-    }
+    Task { @MainActor in
+        pushHandler.openInAppSettings(notification)
+    }
 }

Line range hint 304-310: Correct the failure computed property in PermissionRequestResult extension

The failure computed property uses an if statement without an accompanying return statement inside the block, which will lead to a compilation error.

Apply this diff to fix the logic:

 static var failure: UBPushManager.PermissionRequestResult {
-    if
-        let settingsUrl = UIApplication.ub_appNotificationSettingsURL,
-        UIApplication.shared.canOpenURL(settingsUrl) {
-        .recoverableFailure(settingsURL: settingsUrl)
-    } else {
-        .nonRecoverableFailure
-    }
+    if let settingsUrl = UIApplication.ub_appNotificationSettingsURL,
+       UIApplication.shared.canOpenURL(settingsUrl) {
+        return .recoverableFailure(settingsURL: settingsUrl)
+    } else {
+        return .nonRecoverableFailure
+    }
 }

55-55: Good use of @Sendable for concurrency safety

Adding @Sendable to the PermissionRequestCallback closure ensures that it can be safely passed across concurrency domains, enhancing thread safety and aligning with Swift's concurrency model.


204-204: Appropriate use of @Sendable in authorization closure

Adding @Sendable to the closure in requestAuthorization ensures that the closure can be safely executed in a concurrent environment, promoting thread safety.


225-226: Maintain main actor execution for notification registration

Using Task { @MainActor in ... } ensures that the setting of notification categories and the registration for remote notifications occur on the main actor, which is crucial for updating UI-related components.


Line range hint 270-273: Consistent use of Task { @MainActor in ... } in delegate methods

Wrapping push handler calls within Task { @MainActor in ... } in the UNUserNotificationCenterDelegate methods ensures that UI updates are performed on the main actor, maintaining thread safety.


DispatchQueue.main.async {
Task { @MainActor in
UNUserNotificationCenter.current().setNotificationCategories(self.pushHandler.notificationCategories)

⚠️ Potential issue

Line exceeds maximum allowed length

Line 178 exceeds the maximum line length of 120 characters as indicated by SwiftLint. This could impact code readability.

Consider breaking the line to improve readability:

 Task { @MainActor in
-    UNUserNotificationCenter.current().setNotificationCategories(self.pushHandler.notificationCategories)
+    UNUserNotificationCenter.current()
+        .setNotificationCategories(self.pushHandler.notificationCategories)
     UIApplication.shared.registerForRemoteNotifications()
 }
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
