This still happens on iOS 12.

But, It seems that this doesn't happen on iOS 13.

Open Radar FB7543829: Specific crash since iOS 13.2

Easy steps to reproduce: 
1) Open keyboard settings and enable predictive text and auto-correction features. It’s necessary for reproducing the crash. 2) Run Bumble app and open any chat with another user. 3) Type something till the moment when text replacement variants appear, and the text you entered becomes selected. 4) Switch to the application launcher and kill the Bumble application as fast as possible.

The crash happens whilst the application is terminating.

Open Radar 32830264: Enable eGPU Device Support in Boot Camp

Having one machine to handle everything would be fantastic. eGPU support in Boot Camp is important to working in a lot of CAD/engineering software in Windows due to needing to use a certified graphics card. Ideally some of this software would have macOS versions, but that seems unlikely. Having eGPU support would at least allow us to use one computer to run all macOS software as well as all Windows software.

Open Radar FB761103: Downcasting filters created using `CIFilter.perspectiveCorrection()` from `CIFilter` to `CIPerspectiveCorrection` fails

I am not too sure about the #available macro-looking thing resolves, but more relevantly, CIPerspectiveCorrection is an obj-c protocol, not a class.

Open Radar 7358804: Phone number suggestions don't work

I made a small investigation with Hopper and found interesting stuff. Within [UIPredictionViewController isVisibleForInputDelegate:inputViews:] call there is check against the bitmask 0b100100110000. Each bit in this mask corresponds to a value of UIKeyboardType. Thus predictions are disabled for the following types: UIKeyboardTypeNumberPad UIKeyboardTypePhonePad UIKeyboardTypeDecimalPad UIKeyboardTypeASCIICapableNumberPad Obviously, predictions were disabled for all numerical keyboards and I guess phone pad was added accidentally too. Everything works fine when I swizzle initial function to return "true" in case of phone keyboard, as expected I'm having my phone suggested above the keyboard.

Open Radar 4999496467480576: iOS 11.2 sometimes AASA file is not updated after app installation/reinstallation

Open Radar 7111585: Xcode/Command Line Tools: /usr/bin/python3 cannot find default SSL trust store, resulting in CERTIFICATE_VERIFY_FAILED for all HTTPS requests

Won’t fix

According to Apple it’s a “Won’t fix”. From

So the solution is to use Requests instead.

Open Radar 20673920: Error -10000 getting class of Xcode source document via AppleScript

Apple says the feature has been removed, but it hasn’t been, at least in Xcode 11.3.1. On the bright side, it works again in 11.3.1.

Open Radar FB7577994: Unable to use dynamic frameworks on iOS 13.3.1 with free account

This has been reported before I believe: FB7562472

There is a "workaround":

  • Use a non-Personal Team provisioning profile.
  • Run on the 13.3.1 simulator.
  • Test on a real iOS device running 13.3 or lower.

Open Radar 32830264: Enable eGPU Device Support in Boot Camp

This is the only reason why I still have a PC at home. Once Apple starts supporting eGPU on boot camp I can get rid of my PC.

Open Radar 7103187: CNContactPickerViewController cannot be represented in SwiftUI


You can workaround this bug by using an extra UIViewController wrapper that just presents the CNContactsPickerViewController.
