I can't believe that Xcode requires Catalina starting with 11.4. Are you guys at Apple living under a rock? To enumerate the problems Catalina has would take hours. I can't imagine any technical reasons for forcing Catalina on Xcode, this appears to be pure arbitrariness.   Just FYI: I'm not a Facebook engineer, I don't have 10 development… (Show more)

I want to store 2D and 3D array in core data. I looked everywhere but I could not find anything about it. It would be great if there would any help in this regard

I've not seen this one covered elsewhere, and whilst I've already tried the Feedback Assistant to get it to Apple, I'm not sure if it's being picked up or looked at there...   The problem I've encountered is that whenever I use Disk Utility to create an APFS encrypted volume within a container, it works, but only until I reboot.  When I reboot,… (Show more)

I'm sorry if this isn't in the right place in the forums.   How could my macOS application expose an API for other macOS applications to use? I want other applications to be able to send data to my application, and my application will take care of storing that data. During development, I also want to be able to manually interact with my… (Show more)

I am currently porting an OpenGL rendering backend to Metal (on macOS). 100% repro: 1. Press run App in Xcode. 2. Press frame capture button. 3. A correct looking view appears. [immediately] 4. The mouse pointer turns into the rainbow ball. [immediately] 5. The mouse pointer disappears. [after 5-15 seconds] 6. The external screen shuts off.… (Show more)

I am beginning to pull out my hair: I am trying to create a subview programmatically that would adjust its size automatically when the user resizes the window. More details below. I have searched the documentation (e.g., Apple "Auto Layout Guide"), searched the internet (and tried to follow a lot of examples on stackexchange), all to no avail.  … (Show more)

Hi,   It seems that I cannot find Cocoa framework in the Linked Frameworks and Libraries area. I am using xcode version 10.1. Anyone knows the steps to add it? Thanks.   Best regards, Zhi Chen

Hi there,   I had problems with high CPU load of kernel_task for weeks now and decided to clean up my kexts. I deleted the Silabs Usb Driver kext and invalidated the cache via sudo kextcache -invalidate /  This gave the following strange output   Untrusted kexts are not allowed… (Show more)

I'm loading an OBJ model into a MDLMesh using MDLAsset.  I'm trying to access the raw vertex data, indices, and connectivity for the triangles.  So far I've been able to get the vertices from the MDLMesh (using mdlMesh.vertexAttributeData) and the indices (from the MDLSubmeshes).  But I haven't been able to figure out how to access connectivity -… (Show more)

It looks like the obj file specification allows vp lines with arbitrary data associated (1 2 or 3 floats). I don't see how I can do that through Model IO. The circumstance is that I have some old models created by an artist and he attached values required to animate onto the vertices. I have a proprietary format for the data and it is stored in… (Show more)

Since installing Catalina, I've been experiencing kernel panics when I leave the machine idle (2019 MBP 15 with Vega20). I had no such issues under Mojave. There's a thread here documenting many others experiencing similar behaviour: https://discussions.apple.com/thread/250717203?page=77   I'm quite surprised to see there are no similar threads… (Show more)
