Several app developers are struggling with the inability to provide a separate app icons that looks nice on older macOS versions while at the same time provide Icon Composer icons that look great on macOS Tahoe 26. An ability to provide separate icons is super important to those who have app icons that follow the curvature of the default icon borders (as the corner rounding radius is different for Sequia and Tahoe). Take a look at this for example: https://github.com/ghostty-org/ghostty/issues/7564#issuecomment-3042061547 Question: Is there a definitive/recommended way to address this issue? How can a developer add a glass icon variant that looks good on Tahoe and provide a bitmap icon for older macOS versions? Some background info: Prior to Xcode 26 beta 4, one could add an App Icon to Assets to be used as app icon for legacy macOS versions (Sequia and older) and use a new Icon Composer icon (placed in the project root) for macOS Tahoe 26. Enabling Include all app icon assets under target settings e

After Xcode 26.1 was updated and installing the OS 26.1 simulators, my app started crashing related to transformable properties. When I checked my schema, I noticed that properties with array collection types are suddenly set with an option transformable with Optional(NSSecureUnarchiveFromData)], even though I do not use any transformable types. I verified the macros, no transformable was specified. This is causing ModelCoders to encode/decode my properties incorrectly. This is not an issue when I switch back to OS 26.0 simulators.

I have an iOS app with ExtensionFoundation. It runs well on my local device, but when I upload on the AppStore it gets rejected with: Validation failed Invalid Info.plist value. The value of the EXExtensionPointIdentifier key, AsheKube.app.a-Shell.localWebServer, in the Info.plist of “a-Shell.app/Extensions/localWebServer.appex” is invalid. Please refer to the App Extension Programming Guide at https://developer.apple.com/library/content/documentation/General/Conceptual/ExtensibilityPG/Action.html#/apple_ref/doc/uid/TP40014214-CH13-SW1. (ID: ae8dd1dd-8caf-4a48-9651-7a225faed4eb) The Info.plist in my Extension is: EXAppExtensionAttributes EXExtensionPointIdentifier com.example.example-extension so the Info.plist that causes the issue has been automatically generated by Xcode. I can access it as well, and it says: { BuildMachineOSBuild => 25A354 CFBundleDevelopmentRegion => en CFBundleDisplayName => localWebServerExtension CFBundleExecutable => localWebServer CFBundleIdentifier =>

Hi everyone, I’m currently facing a blocking issue during App Review, and I’d really appreciate some help from anyone who has experienced something similar. My app was rejected under Guideline 2.1 – App Completeness with the following message: “An error message appeared after trying to Sign in with Apple. Device: iPad Air (5th generation), iPadOS 26.1.” The problem is: I cannot reproduce this bug at all, even when testing under the same conditions. ✔ What I tested: Physical iPad Air M2 on iPadOS 26.1 Physical iPhone devices iOS/iPadOS simulators (latest Xcode) TestFlight build (clean install) Debug build installed via Xcode (device connected) In every case, Sign in with Apple works correctly: Authentication sheet displays properly Callback returns the credential User is created/logged in without error No crash, no rejected promise, no empty credential ✔ Environment Using ASAuthorizationAppleIDProvider + ASAuthorizationController Default Apple Sign In button No custom nonce/redirect modificat

I am trying to move over from AppCode/Intellij to Xcode. I am however having a hard time with the version control tools. I know that you can choose side-by-side when you activate code review and select single files. However, if you go into changes and view the list of files that have changed, i can only get inline-view to work. This is really frustrating to me, is there any way to get side-by-side also when you select a file from the changes list? Cheers
