I found a glitch on my app on iOS/iPadOS 16.1. The directory to open files is not saved. I filed this on Feedback Assistant but Apple says that it is a specified behavior. Isn't it a bug? // // ViewController.m // #import "ViewController.h" #import <UniformTypeIdentifiers/UniformTypeIdentifiers.h> @interface ViewController () <UIDocumentPickerDelegate> @end @implementation ViewController { NSURL *directoryURL; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. } - (void)documentPicker:(UIDocumentPickerViewController *)controller didPickDocumentsAtURLs:(NSArray<NSURL *> *)urls { directoryURL = [[urls firstObject] URLByDeletingLastPathComponent]; } - (IBAction)trigger:(id)sender { UIDocumentPickerViewController *picker = [[UIDocumentPickerViewController alloc] initForOpeningContentTypes:@[UTTypeData] asCopy:NO]; picker.directoryURL = directoryURL; [self presentViewController:picker animated:YES completion:nil]; } @end To reproduce the issue. Tap the button and select a file on another directory. Tap the button again. The directory should be the selected one but is the default one.

According to upcoming privacy manifest document, NSUserDefaults is only allowed for a use for the app itself. It is serious for developers who makes App Extensions. https://developer.apple.com/documentation/bundleresources/privacy_manifest_files/describing_use_of_required_reason_api CA92.1 Declare this reason to access user defaults to read and write information that is only accessible to the app itself. This reason does not permit reading information that was written by other apps or the system, or writing information that can be accessed by other apps. Developers, please submit a request to add the permission of App Group. https://developer.apple.com/contact/request/privacy-manifest-reason/

I am creating an xcframework for a static library for iOS, but I am encountering a perplexing issue with Xcode 16.3. When I build an xcframework using C++ in one project and import it into another project, the application runs with corrupted memory. In the framework project, I use os_unfair_lock, but when attempting to lock, the app crashes due to a state error. This suggests that memory corruption is occurring. When the xcframework is built with Xcode 16.2, a proper binary is generated, and the app runs without any problems. Since I do not want to disclose the source code, I am trying to construct a minimal project that reproduces the issue, but so far I have not been successful. Fundamentally, I feel that the compiler in Xcode 16.3 cannot be trusted.

Xcode 15 creates a binary that causes a crash on iOS 12 when I use C++ std::stable_sort. The following code works on iOS 17 but causes a crash on iOS 12. I remember that the earlier Xcode had no problem. It is no problem when I change "std::stable_sort" to "std::sort". FB13430187 // // Tests.cpp // #include <tuple> #include <vector> #include <algorithm> #include <iostream> extern "C" { void execute_tests(void) { using T = std::tuple<size_t, uint64_t *>; std::vector<T> vector = { {7, nullptr}, {4, nullptr}, {9, nullptr} }; std::stable_sort(vector.begin(), vector.end(), [](const T& a, const T& b){ return std::get<0>(a) < std::get<0>(b); }); for (const T& item : vector) { std::cout << std::get<0>(item) << std::endl; } } }

Sender name is incorrect if the name is like "テスト 太郎" and the address book doesn't have the mail address. The bug exists for a long time (at least from iOS 12 or older). It is not resolved in iOS/iPadOS 17 RC. Expected: It shows "テスト 太郎". Actually: It shows "太郎テスト". I made some feedback but they are still ignored. FB6102121 FB8890556 FB8927408

I disable 4 or 5 Finger Gestures on Settings.app > Multi-tasking and Gestures. But in the third-party apps, 4-5 finger touches are sometimes immediately cancelled. Especially, 4-5 finger swipe gesture. I filed this issue to FB19226717. I develop Piano instrument app. 4 or 5 finger touches are required for that kind of apps. Please fix this, Apple.
