This is a problem from Beta 1, but since there is no fix yet in Beta 3, I'd like to raise it. The app is built with macCatalyst, and we have pretty simple tab bar controller setup: viewController = UITabBarController() viewController.tabBar.tintColor = .buttonForegroundColor importWorkflow = ModelImportWorkflow( userInterfaceIdiom: userInterfaceIdiom, workspace: workspace) mergeWorkflow = ModelMergeWorkflow(userInterfaceIdiom: userInterfaceIdiom, workspace: workspace) listWorkflow = ModelListWorkflow(workspace: workspace, userInterfaceIdiom: userInterfaceIdiom) viewController.viewControllers = [ listWorkflow.viewControllable, importWorkflow.viewControllable, mergeWorkflow.viewControllable, ] viewController.modalPresentationStyle = .formSheet We don't do any customizations on the tab bar and in Beta 3 (26.2), there is no way to found the tab bar (attached a user reported image). Please advise what's the course of action. Thanks.

Hi, developers, I maintain a shipped app that uses string concatenation to construct Metal shader and compile on-device. Beta 4 seems disabled __asm keyword, resulting the compilation failure. The error is: v2/GEMMKernel.cpp:229: error: program_source:23:9: error: illegal string literal in 'asm' __asm("air.simdgroup_async_copy_1d.p3i8.p1i8"); The relevant code is available at https://github.com/liuliu/ccv/blob/unstable/lib/nnc/mfa/v2/GEMMHeaders.cpp#L30 although any __asm will trip this. Please give us guidance on whether this is a regression or this will be something enforced in 26 release. Personally, I would consider this as a bug given it won't impact anything "compiled" shaders. Thanks for your patience reading this!
