Hi everyone, I’m testing my Catalyst SwiftUI project on iOS 26 / iPadOS 26 / macOS 26. I started with a NavigationSplitView (triple-column) inside a WindowGroup. On iPad it looks great: the toolbar items merge into the navigation bar, with the three traffic lights. But on Mac Catalyst, the app always reserves a blank safe area below the traffic lights, and places the toolbar on a separate line beneath the title bar. That leaves wasted vertical space I don’t want. What I expect (based on Apple’s WWDC session “Elevate the design of your iPad app”): The toolbar should merge into the title bar with the traffic lights, no separate row. Content should extend into the full height of the window. What I get on Mac Catalyst: Title bar + traffic lights at the top. Then a completely separate toolbar row below it. Safe area inset prevents my content from reaching the top of the window. What I’ve tried: .toolbarRole(.automatic), .editor, .browser → no effect. Hiding the title bar via titlebar?.titleVisibility = .h

Hey everyone, I’ve noticed a big drop in my keyword rankings lately, and it seems linked to Apple’s recent ASO update that’s been trending on Twitter. Has anyone figured out what changed? It looks like app titles may now have less impact on rankings.

Hello, I’m developing an app for both iOS and macOS using Mac Catalyst. On the iOS target, the DeclaredAgeRange framework works fine: I enabled the capability, set the entitlement, and can call the APIs successfully. However, when I build the Mac Catalyst target, I get compile-time errors because DeclaredAgeRange cannot be imported. Environment Xcode 26.0.1 Deployment Target (iOS): 13.0 Mac Catalyst target enabled (same bundle ID, same source code base as iOS version) iOS build works well with DeclaredAgeRange What I tried Added the Declared Age Range capability in Signing & Capabilities for iOS target → works fine. Tried setting Mac Catalyst Deployment Target to macOS 15.0+ and rebuilding → still failed to import. Because it didn’t help, I reverted and removed the separate macOS target setting. On Catalyst, the module simply isn’t available (import DeclaredAgeRange fails). From Apple’s documentation, my understanding is that DeclaredAgeRange should also be supported on Mac Catalyst (SDK 26+). Bu

Beta two keeps hanging during the download process and says connect to wifi (which I am) or after hours it may download the beta 1.4gb file only to have to freeze in next processing step. I have tried all the resets, reinstalling both the watch and the phone running OS26.1 Beta 2 etc. The impact is the watch and the current software implementation is only getting a couple hours of battery usages before going dead

Dear Apple engineers, We have developed a DriverKit (DEXT) driver for an HBA RAID controller. The RAID controller is connected to hosts through Thunderbolt (PCIe port of the Thunderbolt controller). We do plug/unplug tests to verify the developed driver. The test always fails in about 100 cycles with a MacOS crash (panic). The panic contains “LLC Bus error (Unavailable) from cpu0: FAR=0xa40100008 LLC_ERR_STS/ADR/INF=0x80/0x300480a40100008/0x1400000005 addr=0xa40100008 cmd=0x18(ACC_CIFL2C_CMD_RD_LD: request for load miss in E or S state)” At first we assumed that the issue is with hardware. But we did this test on different hosts (MacMini M3 and M4) with different units of our device. The error points to the same physical address FAR=0xa40100008 even if the hosts are different. The 2 full panic logs are attached (one for M4, another one for M3 host). Could you share your understanding of the crash and give any hints on how we can fix it? Please let us know if you need any additional data. Thank you M3

Hi all, I've encountered a potential issue with how the winding order of geometry is handled when their transformations involve negative scaling. I created a simple test asset, a single triangle, to demonstrate this. The triangle's vertices are defined in a counter-clockwise (right-handed) winding order, and its transform has a negative scale on the X-axis. According to the OpenUSD specification, this negative determinant in the transformation matrix should effectively reverse the winding order of the geometry: However, any given gprim's local-to-world transformation can flip its effective orientation, when it contains an odd number of negative scales. This condition can be reliably detected using the (Jacobian) determinant of the local-to-world transform: if the determinant is less than zero, then the gprim's orientation has been flipped, and therefore one must apply the opposite handedness rule when computing its surface normals (or just flip the computed normals) for the purposes of hidden surface detectio

In working with Apple's foundation models, we often want to provide as much context as possible. However, since the model has a context size limit of 4096 tokens, is there a way to estimate the number of tokens beforehand?

hello i am new to apple ecosystem and development i have some coding experience with c# now i like to develop my game for iphone 16 and up(due to ability to run ai models) but i am having hard time figuring out what to use there is a lot of resources for scene-kit but on its doc page it says its deprecated so i look at the reality-kit docs and tutorials and its strictly tells how to develop for visionos and i am really confused about this since there is no tutorials that shows how to develop a game for ios with reality-kit that does not focus visionos. i just want to develop for iphone 16 and up but i cant find resources focuses at that.

Hey everyone. I have a macOS app written in SwiftUI. I have multiple SwiftUI Scenes and Views, but needed to write one specific window in AppKit (an NSPanel, to be specific). The problem I'm facing is- I'm not sure how to incorporate this NSPanel with the rest of my SwiftUI/Observable code. I'm relying on the SwiftUI app cycle. For example, I have a boolean in my view model (observation tracked). I'd like to use this boolean to hide/unhide my NSPanel. Any way to cleanly hook into the viewmodel, or onto some specific observable variables would be very very helpful. Thank you everyone.
