Overview

Hello, I am working on a cross-platform application where IPC between a LaunchDaemon and a LaunchAgent is implemented via Unix domain sockets. On macOS, the socket path length is restricted to 104 characters. What is the Apple-recommended directory for these sockets to ensure the path remains under the limit while allowing a non-sandboxed agent to communicate with a root daemon? Standard paths like $TMPDIR are often too long for this purpose. Thank you in advance!

I'm converting my game from SceneKit to RealityKit. It has a SpriteKit overlay that according to Explore advanced rendering with RealityKit 2 I can add with the code below. The code runs fine if the SKScene only contains a SKSpriteNode (see the commented out line), but when I add a SKShapeNode with a fillColor instead, the app crashes with this error: -[MTLDebugRenderCommandEncoder validateCommonDrawErrors:]:5970: failed assertion `Draw Errors Validation MTLDepthStencilDescriptor uses frontFaceStencil but MTLRenderPassDescriptor has a nil stencilAttachment texture MTLDepthStencilDescriptor uses backFaceStencil but MTLRenderPassDescriptor has a nil stencilAttachment texture ' I don't know enough about low-level graphics and stencils yet to figure out a quick solution, so I would appreciate if anyone could share an easy fix or explanation of what's wrong. Thanks! class ViewController: NSViewController { var device: MTLDevice! var renderer: SKRenderer! override func loadView() { let arView = ARView(frame: NSScreen.main!.frame) view = arView arView.renderCallbacks.prepareWithDevice = { [weak self] device in guard let self = self else { return } self.device = device renderer = SKRenderer(device: MTLCreateSystemDefaultDevice()!) let scene = SKScene() let shape = SKShapeNode(rectOf: CGSize(width: 10, height: 10)) shape.fillColor = .red scene.addChild(shape) // scene.addChild(SKSpriteNode(color: .red, size: CGSize(width: 10, height: 10))) renderer.scene = scene } arView.renderCallbacks.postProcess = { [weak self] context in guard let self = self else { return } let encoder = context.commandBuffer.makeBlitCommandEncoder() encoder?.copy(from: context.sourceColorTexture, to: context.targetColorTexture) encoder?.endEncoding() renderer.update(atTime: context.time) let descriptor = MTLRenderPassDescriptor() descriptor.colorAttachments[0].loadAction = .load descriptor.colorAttachments[0].storeAction = .store descriptor.colorAttachments[0].texture = context.targetColorTexture renderer.render(withViewport: CGRect(x: 0, y: 0, width: context.targetColorTexture.width, height: context.targetColorTexture.height), commandBuffer: context.commandBuffer, renderPassDescriptor: descriptor) } } }

Hi, we were recently approved for the com.apple.developer.web-browser.public-key-credential entitlement and have added it to our app. It initially worked as expected for a couple of days, but then it stopped working. We're now seeing the same error as before adding the entitlement: Told not to present authorization sheet: Error Domain=com.apple.AuthenticationServicesCore.AuthorizationError Code=1 "(null)" ASAuthorizationController credential request failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 "(null)" Do you have any insights into what might be causing this issue? Thank you!

I am testing my app in iOS 26.4 beta and emojis are rendering as squares with ? in the middle . I tested a very simple Text("👾") and I get the same results. It is working fine in 26.3.

I haven’t come across any official documentation regarding the limit on the number of Network Extensions macOS can run. However, I did see some discussions suggesting that Apple might restrict this to 5 extensions in macOS Tahoe. Is there any official confirmation on this?

Have tried to join the developer programme and says its still pending after 3 days. Anyone any idea how long the procedure takes??

Hi, My app wich ID is 6749690414 is waiting for review since Feb 10, is this normal? We have few critical changes to be sent and our business has come to stand still. I'm not trying to bother anyone here, just need to make sure that all is fine and the app will be "reviewed" sooner or later! if there is any place that I can submit a ticket or ask more properly please let me know. Kindest regards Vinesh

Hello, I have a question regarding how prorated refunds are reflected when a user upgrades a subscription. From my understanding, when a user upgrades to a higher-tier subscription, the remaining value of the current subscription is refunded as a prorated amount, typically represented as REFUND_PRORATED or PRORATED_CREDIT. However, when reviewing the available transaction history and refund-related data (including the App Store Server API and transaction history endpoints), I cannot find any field or record that clearly indicates: the actual prorated refund amount, or the credit applied when upgrading to another subscription In other words, while the concept of REFUND_PRORATED seems to exist conceptually, I cannot identify where the actual prorated value or credit applied to the upgrade is exposed in the transaction or refund history. My questions are: Is there any way to retrieve the actual prorated refund or credit amount when a user upgrades a subscription? Is this information available through the App Store Server API (e.g., Get Transaction History) or any other API endpoint? If not, is there any recommended method to determine how much of the previous subscription was credited toward the upgraded subscription? Any clarification would be greatly appreciated. Thank you for your help.

Environment: Hardware: Mac M4 OS: macOS Sequoia 15.7.4 TensorFlow-macOS Version: 2.16.2 TensorFlow-metal Version: 1.2.0 Description: When using the tensorflow-metal plug-in for GPU acceleration on M4, the ReLU activation function (both as a layer and as an activation argument) fails to correctly clip negative values to zero. The same code works correctly when forced to run on the CPU. Reproduction Script: import os import numpy as np import tensorflow as tf # weights and biases = -1 weights = [np.ones((10, 5)) * -1, np.ones(5) * -1] # input = 1 data = np.ones((1, 10)) # comment this line => GPU => get negative values # uncomment this line => CPU => no negative values # tf.config.set_visible_devices([], 'GPU') # create model model = tf.keras.Sequential([ tf.keras.layers.Input(shape=(10,)), tf.keras.layers.Dense(5, activation='relu') ]) # set weights model.layers[0].set_weights(weights) # get output output = model.predict(data) # check if negative is present print(f"min value: {output.min()}") print(f"is negative present? {np.any(output < 0)}")

Dears, Please take a look at case: FB21940123 (Wallet Extension unable to add card) Thanks

Hello, I’m experiencing a situation with my app Waspp that I’m trying to understand. The app was approved by App Review on Feb 24, 2026 and is currently available on the App Store in the United States. However, distribution in the European Union (Belgium and France) is blocked due to the Digital Services Act (DSA) trader verification, which still shows “In Review” in App Store Connect. Some details: App Review completed: Feb 24 DSA compliance submitted: Feb 25 Status: Still “In Review” after more than two weeks Documents requested by Apple Support have already been uploaded via their secure link App availability shows “Cannot Sell” for Belgium and France The app is live and downloadable in the US Because of this, the launch of the app in the EU is currently blocked even though the app itself has been approved. My questions: Is it normal for the DSA trader verification to take this long? Has anyone experienced a similar delay with EU distribution? Is there anything else that can be done from the developer side to unblock the verification? Any feedback or similar experiences would be greatly appreciated. Thanks!

I am working on an e-commerce app (retail/marketplace) that allows users to place orders for both free and paid products. After receiving a DeclaredAgeRange API response — retrieved via the Family Controls / Screen Time framework — indicating that a user is a minor, I want to understand the recommended approach for handling payment flows. Specifically, is it necessary to block payments for users identified as minors via DeclaredAgeRange, even though our app uses server-side encrypted card processing rather than Apple In-App Purchases (StoreKit)? Any guidance on best practices or App Store policy requirements for this scenario would be greatly appreciated.

Hello, My Apple Developer account is currently stuck in an Individual to Organization migration state. The organization verification was declined earlier, but the migration flag is still active on my account. Because of this, my membership benefits are temporarily disabled and I cannot submit new app builds for review. I already contacted Apple Developer Program Support and opened a case. Case ID: 102826815891 However, I have not received a response yet and my account is still locked in the migration state. Has anyone experienced this issue before or know how it can be resolved? Thank you.

Hello, I recently paid for the Apple Developer Program membership, but I am still being prompted to complete payment as if my subscription has not been processed. I have already been charged, and the payment appears to have gone through on my end. However, my account still shows an unpaid or inactive status, and I continue to receive payment prompts. Could you please investigate this issue and confirm that my membership is active? If there is a duplicate charge or a processing error, I would appreciate your assistance in resolving it. Thank you for your help.

We get two error message in Xcode debug. apple.model.catalog we get 1 time at startup, and the nw_protocol_instance_set_output_handler Not calling remove_input_handler on 0x152ac3c00:udp we get on sartup and some time during running of the app. I have tested cutoff repos WS eg.

I don't know if these forums are any good for rumors or plans, but does anybody know whether or not Apple plans to release a library for training reinforcement learning? It would be handy, implementing games in Swift, for example, to be able to train the computer players on the same code.
