show when run

I have something like this drawing in an MTKView (see at bottom). I am finding it difficult to figure out when can the Swift-land resources used in making the MTLBuffer(s) be released? Below, for example, is it ok if args goes out of scope (or is otherwise deallocated) at point 1, 2, or 3? Or perhaps even earlier, as soon as argsBuffer has been created? I have been reading through various articles such as Setting resource storage modes Choosing a resource storage mode for Apple GPUs Copying data to a private resource but it's a lot to absorb and I haven't been really able to find an authoritative description of the required lifetime of the resources in CPU land. I should mention that this is Metal 4 code. In previous versions of Metal, the MTLCommandBuffer had the ability to add a completion handler to be called by the GPU after it has finished running the commands in the buffer but in Metal 4 there is no such thing (it it were even needed for the purpose I am interested in). Any advice and/or pointe

Hi there, ever since I updated to Xcode 26.1, I have been seeing Record UI Button that is showing up on the left hand side which I believe is a new feature. Is there a way to hide this button ? I am using Vim bind with relative line numbers, and now I can't see which line number I am in when writing test cases...

When using CBPeripheralManager in the peripheral role on iPhone 17 series devices (iPhone 17 Air, iPhone 17 Pro) running iOS 26.1 and above, the delegate method peripheralManager:central:didSubscribeToCharacteristic: is never called when a third-party BLE central device attempts to connect and subscribe to a characteristic. This functionality works correctly on all previous iPhone models and iOS versions. (This worked previously for the same iPhone 17 Air/Pro when running iOS 26.0.1.)

Hello! I have read most of the Background Tasks Resources here https://developer.apple.com/forums/thread/707503 - but still have a few questions that I need clarified. To provide our context, our usecase is that our user wants to upload files to our servers. This is an active decision by the user to initiate the upload, but we also want make sure the files are uploaded, even if the user chooses to background our app. If we use a URLSession.backgroundto initiate the uploadTask, I understand that we are passing it of to the urlsession deamon to handle the upload. Which is great, if the user chooses to background our app. But, what if they just stay with the app in the foreground? Will it start uploading immediately? Can we expect the same latency that a standard URLSession will provide? And the potential delay will only occur if they actually background our app. Also, what happens if a background upload is in-progress and the user enters our app again? Will it gain priority, and run with similar latenc

I haven’t been able to get this to work at any level! I’m running into multiple issues, any light shed on any of these would be nice: I can’t implement a bloom filter that produces the same output as can be found in the SimpleURLFilter sample project, after following the textual description of it that’s available in the documentation. No clue what my implementation is doing wrong, and because of the nature of hashing, there is no way to know. Specifically: The web is full of implementations of FNV-1a and MurmurHash3, and they all produce different hashes for the same input. Can we get the proper hashes for some sample strings, so we know which is the “correct” one? Similarly, different implementations use different encodings for the strings to hash. Which should we use here? The formulas for numberOfBits and numberOfHashes give Doubles and assign them to Ints. It seems we should do this conversing by rounding them, is this correct? Can we get a sample correct value for the combined hash, so we can ve

I am using XCode (Version 26.0.1 (17A400)) -> Archive -> Distribute App (or Validate App) to upload my iOS app into App Store Connect. However I am always getting this error: Uploading SPI errors: Validation failed (409) The app contains one or more corrupted binaries. Rebuild the app and resubmit. NSUnderlyingError : Validation failed (-19241) The app contains one or more corrupted binaries. Rebuild the app and resubmit. code : STATE_ERROR.VALIDATION_ERROR I tried exporting the app as an IPA and uploading with Transporter, but I see the same error. I couldn't find any other useful logs or error messages. More info: I have created the app in App Store Connect and this is my first time uploading. The app can build and run on my physical phone and emulator without any problem. Would be great to get some help! Thanks!
