1-48: Remove log file from version control.This log file should not be committed to the repository as it:
- Contains sensitive development environment information (simulator device paths)
- Will continuously change during development, causing unnecessary version control noise
- Can grow large over time
Add this file to
.gitignoreand remove it from the repository:+# Log files +*.log +log.txtConsider implementing structured logging with appropriate log levels instead of verbose console output for production code.

12-16: Improve image rendering for arbitrary sizesSetting
Aspect="AspectFit"prevents distortion when loading screenshots or photos of unknown dimensions.- <Image x:Name="Img" - Source="dotnet_bot.png" - SemanticProperties.Description="Cute dot net bot waving hi to you!" - HeightRequest="200" - HorizontalOptions="Center" /> + <Image x:Name="Img" + Source="dotnet_bot.png" + SemanticProperties.Description="Placeholder image" + HeightRequest="200" + Aspect="AspectFit" + HorizontalOptions="Center" />
18-24: Remove dead commented-out controls to keep XAML cleanIf the label/button are no longer needed, deleting them avoids noise and reduces merge-conflict surface.
- <!-- <Label Text="Click button to open Safari. Then click on Share button" - HorizontalOptions="Center"/> - - <Button - Text="Open Safari" - Clicked="OnClicked" - HorizontalOptions="Center" /> -->iOSExtensions/ShareExtension/AppContainer/Platforms/iOS/Info.plist (1)
35-45: Consider using a more specific URL scheme for security.The URL scheme
mauiappis fairly generic and could potentially be registered by other apps, leading to URL interception. Consider using a more specific scheme that includes your company or app identifier, such asvladislavantonyuk-mauiapporcom-vladislavantonyuk-container.- <key>CFBundleURLName</key> - <string>com.vladislavantonyuk.container</string> - <key>CFBundleURLSchemes</key> - <array> - <string>mauiapp</string> - </array> + <key>CFBundleURLName</key> + <string>com.vladislavantonyuk.container</string> + <key>CFBundleURLSchemes</key> + <array> + <string>com-vladislavantonyuk-container</string> + </array>iOSExtensions/ShareExtension/AppContainer/MainPage.xaml.cs (1)
15-18: Remove commented code.The commented-out
OnClickedmethod should be removed rather than left in the codebase. Version control maintains the history if needed.- // private async void OnClicked(object sender, EventArgs e) - // { - // await Launcher.OpenAsync("https://vladislavantonyuk.github.io/"); - // }iOSExtensions/ShareExtension/AppContainer/App.xaml.cs (2)
5-8: Consider following standard naming conventions.While the warning suppression works, consider following standard C# naming conventions where private fields use underscore prefix. The current naming is actually correct for private fields.
You can remove the warning suppression as
_mainPagefollows standard conventions:-#pragma warning disable IDE1006 // Naming Styles private MainPage _mainPage; -#pragma warning restore IDE1006 // Naming Styles
10-12: Remove excessive blank lines.Multiple consecutive blank lines reduce code readability.
- -iOSExtensions/ShareExtension/AppContainerExtension/ShareViewController.cs (2)
29-35: Remove commented-out codeThe commented code adds clutter and appears to be an alternative implementation that's not being used.
69-108: Extension only processes first image attachmentThe loop iterates through all attachments but returns after processing the first image. Consider processing all images or documenting this limitation.
Would you like me to implement support for multiple image attachments?

Pull Request Overview
This PR implements image sharing functionality from an iOS Share Extension to a main MAUI app. When users share images from the iOS Photos app or screenshot editor, the extension saves the image data to a shared app group and opens the main app via a custom URL scheme. The main app then retrieves and displays the shared image.
- Added iOS Share Extension project with image processing and app group communication
- Implemented custom URL scheme handling in the main app to receive shared images
- Added app group entitlements to both extension and main app for secure data sharing

41-49: Avoid async void in override methods.Using
async voidin an override method can lead to unhandled exceptions and unpredictable behavior. iOS may not wait for the async operation to complete.
70-96: Multiple unaddressed issues in image loading logic.Several previously identified issues remain unaddressed:
- Missing return statement: After
TrySetResult(false), execution continues and may callTrySetResult(true).- Hardcoded app group identifier: Should be extracted to a constant.
- Unsafe null-forgiving operator: Using
data!without proper null checking.Apply these fixes:
+private const string APP_GROUP_IDENTIFIER = "group.com.yourcompany.mauiapp"; if (itemProvider.HasItemConformingTo(UniformTypeIdentifiers.UTTypes.Image.ToString())) { itemProvider.LoadItem(UniformTypeIdentifiers.UTTypes.Image.ToString(), null, (nsObject, error) => { NSData? data = null; if (nsObject is NSUrl url)//from photos { data = NSData.FromUrl(url); } else if (nsObject is UIImage uiImage)//from screenshot editor { data = uiImage.AsPNG(); } - if (data is null) tcs.TrySetResult(false); + if (data is null) + { + tcs.TrySetResult(false); + return; + } - var userDefaults = new NSUserDefaults("group.com.yourcompany.mauiapp", NSUserDefaultsType.SuiteName); + var userDefaults = new NSUserDefaults(APP_GROUP_IDENTIFIER, NSUserDefaultsType.SuiteName); - userDefaults.SetValueForKey(data!, new NSString("shared_image")); + userDefaults.SetValueForKey(data, new NSString("shared_image"));
109-115: Improve error handling - method masks failures.The catch block doesn't properly handle errors and still returns true, which masks failures from callers.
catch (System.Exception) { //log ex + return false; } -return true;
134-141: Add support for iOS versions below 18.The current implementation only works on iOS 18+ and returns false for older versions, effectively breaking the feature for most users.
Implement the fallback:
else { - //TODO: fix for > ios18 versions - // var sel = new Selector("openURL:"); - // var result = application.PerformSelector(sel, url, 0); - // return result != null; - return false; + var sel = new ObjCRuntime.Selector("openURL:"); + var result = application.PerformSelector(sel, url, 0); + CompleteExtension(); + return result != null; }
153-153: Use Array.Empty for better performance.Use
Array.Empty<NSExtensionItem>()instead ofnew NSExtensionItem[0]for better performance and consistency with modern C# practices.-ExtensionContext?.CompleteRequest(new NSExtensionItem[0], null); +ExtensionContext?.CompleteRequest(Array.Empty<NSExtensionItem>(), null);
51-67: Critical: Missing Safari URL sharing and null safety issues.Multiple critical issues need to be addressed:
- Missing Safari URL sharing: Per PR objectives, this breaks existing Safari URL sharing functionality.
- Missing null checks: Code accesses
ExtensionContext?.InputItems[0]without verifying the array exists and has elements.Add Safari URL support and null checks:
private async Task<bool> ExportImageToMainApp() { try { var tcs = new TaskCompletionSource<bool>(); + if (ExtensionContext?.InputItems == null || ExtensionContext.InputItems.Length == 0) + { + CompleteExtension(); + return false; + } var extensionItem = ExtensionContext?.InputItems[0] as NSExtensionItem; var attachments = extensionItem?.Attachments; - if (attachments is null) + if (attachments == null || attachments.Length == 0) + { + CompleteExtension(); return false; + } - foreach (var itemProvider in attachments) + foreach (var itemProvider in attachments) { + // Handle URLs (for Safari sharing) + if (itemProvider.HasItemConformingTo(UTTypes.Url.ToString())) + { + itemProvider.LoadItem(UTTypes.Url.ToString(), null, (nsObject, error) => + { + if (nsObject is NSUrl url) + { + var userDefaults = new NSUserDefaults(APP_GROUP_IDENTIFIER, NSUserDefaultsType.SuiteName); + userDefaults.SetString(url.AbsoluteString, new NSString("shared_url")); + userDefaults.Synchronize(); + tcs.TrySetResult(true); + } + else + { + tcs.TrySetResult(false); + } + }); + continue; + } + if (itemProvider.HasItemConformingTo(UniformTypeIdentifiers.UTTypes.Image.ToString()))

12-12: Consider making app group identifier configurable.While using a constant is better than a magic string, the app group identifier could be made configurable through app settings or build configuration to support different environments (dev, staging, production).
Consider reading from configuration:
private static string AppGroupIdentifier => Microsoft.Maui.Controls.Application.Current?.Resources?["AppGroupIdentifier"]?.ToString() ?? "group.com.yourcompany.mauiapp";

39-53: Async void override method still not addressed.The past review comment about avoiding
async voidin override methods remains unaddressed. This can lead to unhandled exceptions and unpredictable behavior since iOS may not wait for the async operation to complete.Consider the previously suggested approach using Task.Run or a synchronous method with completion handlers.
55-112: Safari URL sharing functionality still missing.The method only handles image attachments and doesn't support URL attachments, which breaks the Safari URL sharing functionality as mentioned in the PR objectives. This was flagged in a past review comment with specific implementation guidance.
Please implement URL handling alongside image handling to maintain backward compatibility with Safari sharing.
62-63: Missing bounds check for InputItems access.Accessing
ExtensionContext?.InputItems[0]without checking if InputItems has any elements could cause an IndexOutOfRangeException.Add a null and bounds check before accessing the first element.
87-90: Missing return statement after TrySetResult(false).The code continues execution after setting the task result to false, which could lead to unexpected behavior including calling TrySetResult(true) later.
Add a return statement after
tcs.TrySetResult(false);to prevent further execution.
146-149: Consider using Array.Empty() for better performance.The past review comment suggested using
Array.Empty<NSExtensionItem>()instead of[]for better performance and consistency with modern C# practices.

39-53: Improved error handling, but async void remains a concern.The addition of try-catch-finally block with
CompleteExtension()in the finally block significantly improves error handling and ensures the extension context is always completed. However, the method remainsasync void, which can still lead to unhandled exceptions in the iOS runtime.Note: The
async voidissue from previous reviews remains, but the error handling improvements make this much more robust.
87-91: Critical: Missing return statement after TrySetResult(false).After calling
tcs.TrySetResult(false)when data is null, the code continues execution and may callTrySetResult(true)later, causing unexpected behavior.Apply this fix:
if (data is null) { tcs.TrySetResult(false); + return; }
70-100: Missing Safari URL sharing functionality.The method only handles image attachments and ignores URL attachments, breaking the existing Safari URL sharing functionality mentioned in the PR objectives. Both image and URL sharing must be supported.
Add URL handling before the image handling:
foreach (var itemProvider in attachments) { + // Handle URLs (for Safari sharing) + if (itemProvider.HasItemConformingTo(UTTypes.Url.ToString())) + { + itemProvider.LoadItem(UTTypes.Url.ToString(), null, (nsObject, _) => + { + if (nsObject is NSUrl url) + { + var userDefaults = new NSUserDefaults(AppGroupIdentifier, NSUserDefaultsType.SuiteName); + userDefaults.SetString(url.AbsoluteString, new NSString("shared_url")); + userDefaults.Synchronize(); + tcs.TrySetResult(true); + } + else + { + tcs.TrySetResult(false); + } + }); + continue; + } + if (itemProvider.HasItemConformingTo(UTTypes.Image.ToString()))

🔇 Additional comments (4)
iOSExtensions/ShareExtension/AppContainer/Platforms/iOS/AppDelegate.cs (1)
5-14: LGTM! Constants properly defined.The addition of the UIKit using statement and private constants for URL scheme, host, app group identifier, and shared image key addresses previous feedback about avoiding magic strings. The constant names follow proper naming conventions.
iOSExtensions/ShareExtension/AppContainerExtension/ShareViewController.cs (3)
1-12: LGTM! Using statements and constants properly defined.The addition of the
UniformTypeIdentifiersusing statement and extraction of hardcoded values to constants addresses previous feedback. The constant names follow proper conventions and improve maintainability.
115-147: LGTM! Excellent responder chain traversal and iOS version handling.The implementation properly:
- Traverses the responder chain to find UIApplication
- Handles iOS 18+ with modern API
- Provides fallback for iOS < 18 using selector
- Calls
CompleteExtension()in both code paths- Uses constant for maximum attempts to prevent infinite loops
149-152: LGTM! Clean encapsulation of extension completion.The method properly encapsulates the extension context completion logic and uses the modern empty array literal syntax.
