Open Radar 31154770: Instruments 8.3 beta: false positive leak reported

Post by me, August 14th 2019, 6:21 PM

I don’t believe the issue is solved. It’s hard to tell because, in Xcode 11 beta 5, I can’t get the app to launch from Instruments. See attached video. However, the memory graph debugger is reporting the same leak as before.

Attached files also posted here for posterity: Sample project updated for Xcode 11 beta 5: Video recording of reproduction of issue:

Open Radar 6912686: calculator: some unary ops in programmer RPN mode broken

In the Calculator app, in RPN mode, in Programmer mode, the outcome of some, but not all, unary operations is 0 instead of the expected value when the operation is repeated.

steps to reproduce: - start Calculator - hit cmd-3 for programmer mode - hit cmd-r for RPN mode (if not enabled already) - enter "1" - hit "<<", the unary shift left operator - result is "2". Ok. - hit "<<" again. - result is "4". Ok. - hit "RoL", the unary rotate left operator - result is "0". Not ok. Expected "8". - enter "1" - hit "RoL" - result "2". Ok. - hit "RoL" - result "0". Not ok. Expected "4".

The "RoR", "2's complement", and "1's complement", "byte flip", and "word flip" unary operators are similarly broken.

The ">>" unary operator is ok, like "<<".

Also, perhaps related (also an unexpected "0" outcome): - enter "1" - hit "enter" - a "0" is pushed onto the stack, where in Basic and Scientific mode a duplicate of the top-of-stack is pushed ("1" in this case)

Open Radar 35451006: Cannot create AVDisplayCriteria

Please refer to:

UIAppSupportsHDR specifies whether the app supports HDR mode on Apple TV 4K. If the key's value is NO and Apple TV 4K is in HDR mode, Apple TV switches to SDR mode before launching the app, and it switches back to HDR mode when the app resigns. If the key is not present or its value is YES, the device remains in HDR mode when the app launches. HDR mode on Apple TV 4K uses the GPU to compose the content that appears on the screen. GPU bound apps, such as games, can access more of the GPU by opting out of HDR support, that is, setting UIAppSupportsHDR to NO. However, switching between HDR and SDR modes may cause color flashing to appear on the screen. Apps should only opt out when absolutely necessary. This key is supported in tvOS 11.2 and later.

As a recommendation, perhaps the keyboard shortcut could be the same Control–Option–Command-T keyboard shortcut that is available in Setup Assistant to open Terminal.
