https://developer.apple.com/forums/thread/788293 In the above thread, I received the following response: "When building with the SDK from the next major release after iOS 26, iPadOS 26, macOS 26 and visionOS 26, UIKit will assert that all apps have adopted UIScene life cycle. Apps that fail this assert will crash on launch." does this mean that there will be no app crashes caused by UIKit in iOS 26, but there is a possibility of app crashes when building with the SDK provided from iOS 27 onwards?

I found the following statement on the site TN3187: Migrating to the UIKit scene-based life cycle | Apple Developer Documentation: "Soon, all UIKit based apps will be required to adopt the scene-based life-cycle, after which your app won’t launch if you don’t. While supporting multiple scenes is encouraged, only adoption of scene life-cycle is required." In this post, you mentioned that the timing is undecided. https://developer.apple.com/forums/thread/785588 I would like to confirm the following two points additionally. Could you please confirm whether the timing when the app will not be able to launch is during an iOS update or at another specific time? This will change our response policy. Does "your app won’t launch" mean that already distributed apps will also not be able to launch? Or does it mean that newly developed apps will fail to build or be rejected during app review?

I found the following statement on the site https://developer.apple.com/documentation/technotes/tn3187-migrating-to-the-uikit-scene-based-life-cycle: "Soon, all UIKit based apps will be required to adopt the scene-based life-cycle, after which your app won’t launch if you don’t. While supporting multiple scenes is encouraged, only adoption of scene life-cycle is required." Could you please clarify when exactly apps will no longer be able to launch if they do not adopt the scene-based life-cycle? I would like to confirm the deadline as the impact of this change is significant.

Hello, I am experiencing slow image retrieval when using the requestImageForAsset:targetSize:contentMode:options:resultHandler: method in my application. The delay is significantly impacting the performance of my app. Here are the details of my implementation: for (PHAsset *asset in assets) { @autoreleasepool { PHImageManager *imageManager = [PHImageManager defaultManager]; PHImageRequestOptions *options = [[PHImageRequestOptions alloc] init]; options.synchronous = YES; options.deliveryMode = PHImageRequestOptionsDeliveryModeFastFormat; options.resizeMode = PHImageRequestOptionsResizeModeNone; [imageManager requestImageForAsset:asset targetSize:CGSizeMake(100, 100) contentMode:PHImageContentModeAspectFill options:options resultHandler:^(UIImage *thumbnail, NSDictionary *info) { CameraRollCellDto *cellDto = [[CameraRollCellDto alloc] init]; cellDto.index = index; cellDto.thumbnail = thumbnail; cellDto.propertyDate = asset.creationDate; if (self.segmentedTorikomi.selectedSegmentIndex == SEG_INDEX_IKKATSU) { cellDto.isSelected = YES; } else { cellDto.isSelected = NO; } [list addObject:cellDto]; }]; index++; } } Has anyone else encountered this issue? Are there any known solutions or optimizations that can help improve the speed of image retrieval using this method? Thank you for your assistance.

Hello, I recently replaced NSURLConnection with NSURLSession in my application, and I have noticed a significant decrease in network speed. I am seeking advice on why this might be happening and how to resolve the issue. Here is the code before the change: Old Code: - (void)execute:(id<STHttpEntity>)entity { [entity addHeader:API_HDR_CLASS_NAME value:self.apiClass]; [entity addHeader:API_HDR_METHOD_NAME value:self.apiMethod]; NSMutableURLRequest *req = [self createRequest:entity]; self.connection = [[NSURLConnection alloc] initWithRequest:req delegate:self]; [self.connection start]; } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { [self clearConnectionTimeout]; self.requestData = nil; if (self.httpStatus != HTTPSTATUS_OK) { [self callFailedWithStatus:self.httpStatus]; return; } [self callSucceeded]; } And here is the code after the change: New Code: - (void)execute:(id<STHttpEntity>)entity { [entity addHeader:API_HDR_CLASS_NAME value:self.apiClass]; [entity addHeader:API_HDR_METHOD_NAME value:self.apiMethod]; NSMutableURLRequest *req = [self createRequest:entity]; NSURLSessionConfiguration *sessionConfig = [NSURLSessionConfiguration defaultSessionConfiguration]; NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfig delegate:self delegateQueue:nil]; self.dataTask = [session dataTaskWithRequest:req]; [self.dataTask resume]; } - (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didCompleteWithError:(nullable NSError *)error { [self clearConnectionTimeout]; self.requestData = nil; if (error) { [self callFailed:error]; } else { [self callSucceeded]; } } Issue: After replacing NSURLConnection with NSURLSession, the network speed has significantly decreased. The new implementation seems to be much slower than the old one. Questions: 1.What could be the reasons for the significant decrease in network speed after switching to NSURLSession? 2.Are there any specific configurations or best practices for NSURLSession that I should be aware of to improve performance? 3.Is there any known issue with NSURLSession that could cause such a performance drop? Any insights or suggestions would be greatly appreciated. Thank you in advance for your help!

We are currently in the process of migrating our application from using ALAssetsLibrary to PHPhotoLibrary to ensure compatibility with the latest versions of iOS. However, we have noticed a discrepancy in the file sizes of images obtained using PHPhotoLibrary compared to those obtained using ALAssetsLibrary. Specifically, we would like to understand the following points: 1.Reason for File Size Differences: What are the reasons for the difference in file sizes between images obtained using ALAssetsLibrary and those obtained using PHPhotoLibrary? Could you provide detailed information on the settings and options in PHPhotoLibrary that affect the size and quality of the images? 2.Optimal Settings: What are the optimal settings in PHPhotoLibrary to obtain images with the same quality and file size as those obtained using ALAssetsLibrary? If possible, could you provide code examples or recommended option settings?
