Try to change accuracy. I read there were recent improvement to QRCode, to read smaller images. In any case, you should file a bug report.

Do you mean you stop the program on simulator ? That's not a normal stop of the app, so its logical to get an error exit. Which version of Xcode ? And why is it a problem to have such an exit ?

Could you clarify the use case ? your app is closed you squeeze the iPhone that opens your app. But how could it open your app specifically ? You can detect a shake gesture in your app, but that supposes your app is already active. In iOS 14, you can add external buttons (with external hardware) to perform some actions (accessibility settings). But I did not see something close to what you look for.

The Swift programming language 5.3 refers to Xcode 12. So I assume they take it into consideration…

I tried and could not reproduce the crash. I created a project for iOS (not multiplatform) UIKit Storyboard I tested with 2 date pickers style: on automatic one as wheels Mode is set to Date Xcode 12.4 Tested on simulator iPhone 11 ProMax 14.4. I scrolled to 1996. No crash. Could you describe your exact set up ?

I looked at video and did the test with the same DatePicker configuration. No crash. I tested with 12Pro simulator. No crash. Could you post the complete crash log, it is not possible to read on the video. I am also using 12.4 (12D4e) Tested on Catalina 10.15.7 (19H114) What is your MacOS version ? Maybe you have an Xcode installation issue ?

Thanks for feedback. I'm sorry not to know better option. Maybe you could ask the question to support ? Or if really important use a DTS ticket ? And don't forget to close the thread. Have a good day.

Could you show the complete func in which you set the color ? And tell where exactly you do it (in which controller).

I haven't found anything in the Apple documentation, but I'm assuming attributed text is not supported in localization or accessibility. What do you mean exactly ? Can you show how you call the NSAttributed text to display ?

some SFSymbols is not properly centred Could you give examples of some OK and some not OK ? When not OK, it it a few pixels offset or much more ?

I looked at the icons themselves (importing both function and gear in a UIImage). It appears they have a very different aspect ration: func is wide: like 70 * 44 gear is square : like 44 * 44 Hence, when drawing, they scale to fit ; and the height of function icon is reduced. Maybe a solution is to create your own icon and make it square (entered in the square you want). Update I did it, creating a 40*40 icon and it works quite well. I had a series of steps to get there : - screenshot the iconpasted in drawing in openOffice - screenshot a square around it (it has white background)pasted again in open office - with Tools > Color replacer, change white color to transparentselected the object and copied - in Preview, create from pasteboardresize to 40 * 40 and name "f of x" - then copied in Xcode project 10. - and used it as the image. Note: at step 8, you may fine tune the values (changing resolution, changing a little bit the size, but keep it square).

creating my own image just didn't feel right What is not OK with an image ? The test I did is not so bad. If you want to post an email address for a short moment (edit your post then within the next hour to avoid leaving your email), I will send you copy of test app I created for this. why the imageInsets do not work on UIImages that are initialized with an SFSymbol but do work when I use an image which is in an Assets folder. Yes, that's surprising. I assume the reason is that SF is not exactly an image, or is not handled as such. It may be closer to an emoji. In anycase, that is worth a bug report.

How much RAM ? Did you look in Activity Monitor to find what is using most resources ?

That means that each time you type a character, there is some processing of the whole String. And probably the time grows linearly. So if it takes 10 ms (unnoticeable) for a 1K string, it will take 4s for 400K String. You should file a bug request, at least against doc to inform about it. Note: 400K is more than a sizeable String…

The forum is not the place to call at Apple. Either file a bug report or call support. upgrading my family yesterday 5th February 2021 to IOS 14.4 all of my devices that are Apple What did you upgrade ? Several devices ? Did you do it in a single operation ? Could you describe the sequence of actions for this family upgrade, and when you first noticed the problem. I would try to unregister a device from the wifi network (forget the network) and register again.
