SwiftUI List performance

MacOS system settings allow the user to select one of a number of number formats. My app behaves differently depending on the format (taken from the system Locale), so I need to test every combination. Thus far I have been successful at creating Locale objects with various identifiers that map to the different formats, like: let westEuropeanLocale = Locale(identifier: en_DE) However, I can't find a locale that maps to using . as a decimal point, and space as a thousands separator, even though it's a standard option (3rd in this list): Any suggestions on how to create a test for this number format?

After upgrading to a new iPhone and restoring from an iCloud backup using the same Apple ID, I noticed an issue with Health app permissions. ■ What is happening On my previous iPhone, an app had permission to read step count data. After restoring to the new iPhone, the app still appears in the Health app under Sources. However, when I tap the app, the usual data type permission toggles (such as Steps) are not displayed at all. As a result, the app is unable to read step count data. ■ Additional details The app itself seems to be recognized as a Health data source. However, the data type permission screen is empty. No ON/OFF switches are shown. The backup was created on iOS 18, and the restore was performed on iOS 26. I have not yet confirmed whether this also happens with other iOS version combinations. ■ Questions Is it expected behavior that Health app permissions (per data type) are not restored via iCloud backup? Has anyone experienced a similar situation where the app appears under Sources but t

The scenario is, in a macOS app (primarly), main thread needs to wait for some time for a certain 'event'. When that event occurs, the main thread is signaled, it gets unblocked and moves on. An example is, during shutdown, a special thread known as shutdown thread waits for all other worker threads to return (thread join operation). When all threads have returned, the shutdown thread signals the main thread, which was waiting on a timer, to continue with the shutdown flow. If shutdown thread signals the main thread before the later's timer expires, it means all threads have returned. If main thread's timer expires first, it means some threads have failed to join (probably stuck in infinite loop due to bug, disk I/O etc.). This post is to understand how main thread can wait for some time for the shutdown thread. There are two ways: a) dispatch_semaphore_t b) pthread conditional variable (pthread_cond_t) and mutex (pthread_mutex_t). Expanding a bit on option (b) using conditional variable and mutex: // This me

Hello everyone, I am looking for technical clarification regarding potential rate limits when automating frequent iOS device resets. In my workflow, I need to reset test devices multiple times per day using the EraseDevice MDM command, often combined with the ReturnToService flag for automated setup. I understand that after a full reset, the device undertakes several critical steps to become operational again, including device activation, system app installation, MDM re-enrollment, and subsequent validation of developer certificates for internally distributed apps. Based on Apple’s documentation and my own observations, I am aware of the following domains being involved in these processes: Device Activation: albert.apple.com, gs.apple.com, captive.apple.com, humb.apple.com, static.ips.apple.com, sq-device.apple.com, tbsc.apple.com, time*.apple.com System App Installation: *.itunes.apple.com, *.apps.apple.com, *.mzstatic.com MDM Enrollment: Communication with Apple ADE servers followed by the MDM server.

Hello everyone, I am seeking advice regarding a persistent Guideline 4.2 (Minimum Functionality) rejection for my app, Naxçıvan Avto. My app is a specialized automotive marketplace designed specifically for the Nakhchivan region. The Issue: The App Review team has stated that the app's usefulness is limited by minimal functionality and lacks sufficient app-like features. However, the app is built strictly around the services provided by our company and the specific requirements of our local automotive industry. Current Functionality: • Dynamic Regional Marketplace: Real-time car and license plate listings with detailed technical data (VIN codes, mileage, engine specs). • Localized Financial Tools: Filters and categorization for Cash (Nağd), Credit, and Barter options, which are essential for our regional business model. • Real-time Push Ecosystem: Integration with Supabase Edge Functions to notify users about new listings and approval statuses. • Native Tooling: Includes a financial calculat
