I guess some of the tasks of the many going are doing something wrong. I cannot say anything more under the currently shown info. Can you show all the code of the tasks going on? As you have background fetch, it might be a problem of multithreading, which is hard to reproduce.

Thanks for trying. But I do not see what you do to load the adress saved in the file. Adding images (you may need to use Your Answer instead of comments) would help.

Can you try to explain the Shortcuts? If we have no need to download, that would be better.

Can you explain what is the problem of your current code? Does it not compile? Or crashes on runtime? Or the result is unexpected?

It looks as if UTF-8 bytes shown as ISO-8859-1. Can you show the details of your Shortcuts?

You should better check News and Updates. (Link shown below every page of the developer site.) App Store submissions now open for iOS 15 & iPadOS 15 Starting April 2022, all iOS and iPadOS apps submitted to the App Store must be built with Xcode 13 and the iOS 15 SDK. Unless the detailed date is announced, you should better take it as the first day of April 2022.

Please show as much info of the crash, all the message shown in the debug console, stack traces and your code. Generally Leaks is a tool to find memory leaks, not for finding the reason of crashes.

I guess you mean the new Swift Playgrounds which can develop iPhone/iPad apps on iPad. It usually is referred to as Swift Playgrounds 4. You should visit this old thread first. Even for now that the first version of iPadOS 15 is released, Swift Playgrounds is marked with two stars in the iPadOS 15 page, which means ** Available late 2021. I'm not sure if it would be included in the future version of iPadOS 15, or released as a separate app in the App Store, but I do expect that the beta version of it would be available on the Apple Developer site when ready. so i want to know when the swift playground 5 came out and how can i update it Apple rarely reveals their future plans except on events such as WWDC. You should better wait on the Developer site watching the official announcements.

I am curious to know why Xcode 13 is not available for download on the official site? In recent years, new Xcode had been available to be installed through Mac App Store first, and it was put in the More Downloads pages hours or days later. on my organization system App Store is not accessible for security concerns. So using the official website is the only option to download the latest Xcode - 13. Then you may need to wait for days. As far as I remember, you would not have to wait months. Or another option, make your organization change the security rule, if downloading the new Xcode is an urgent task for your organization.

@sykste, as I wrote, binary floating point number like Double cannot represent values like 5.02 nor .06 precisely. You may need to use Decimal or find a more suitable way of rounding for your purpose. Better start your own thread with detailed description (including your code) showing your purpose.

I tried your code a few tens of times with 100 millions elements in contacts. It never crashed. So the number of String comparison does not matter. I guess it is a problem of multithreading, as it may be revealed only when huge number of elements involved. Anyway, you should better concentrate on the first thread of yours and respond to eskimo.

Whether the issue is caused by any of the changes of iOS or not, you should better find a better place to ask about ReactNative. ReactNative is not a framework of Apple's and it is the responsibility of the author of the framework to adapt to the changes of the supported OS.

It depends on what sort of graphics library you want to use. What do you want to use?

Why are they called Cancellables I'm not sure what would satisfy your curiosity, Cancellable is a very common naming when you can cancel on it. what is the advantage of using combine bindings over computed properties in SwiftUI. Have you watched the WWDC session video when Combine was introduced? Introducing Combine So across the Cocoa SDK you'll find plenty of asynchronous interfaces. Some you saw here like Target/Action, but there's a lot more, including NotificationCenter and lots of ad-hoc callbacks. These are API's that take a closure or completion block. All of these things have important and different use cases. But sometimes when you need to compose them together, it can be a little bit challenging. Using Combine, you can handle all the asynchronous data/event sources in a unified manner. That can be a big advantage for developers struggling to compose such different kinds of asynchronous sources. If you do not feel it an advantage, it may be better for you to stay on the ways like computed property.
