It works with Xcode 26.2 Beta! And the simulator on iOS 26.2 as well. It was indeed a version issue, because it also works on Xcode 26.1.1 with a Mac run destination. I just hadn’t tested that before. Thank you very much!

Tahoe 26.2 beta 1, Xcode 26.1.1, iPhone Air simulator 26.1 This might be the issue. Could you try updating your Xcode to 26.2 such that your Mac OS and Xcode version match? The simulator for iPhone Air 26.1 is actually running the model on your Mac (26.2) so that version mismatch could be causing this error. Kindly let us know if that makes any difference!

@Etresoft The goal is to use older Asset Catalog based app icons for pre-26, and new Icon Composer based app icons for 26+. With Xcode 26.0, you could make it work using the --enable-icon-stack-fallback-generation=disabled setting. But as of Xcode 26.1, that setting is now being ignored and when the app is run, the Icon Composer based app icon is used for all versions, pre and post 26. While this thread is about macOS, it equally applies to iOS apps. I'm sticking with Xcode 26.0 because I want my old app icons for iOS 18 and older. Xcode 26.1 is now preventing this from being possible.

I encountered the same issue, which occurs only on iOS 26.1 when building the app with Xcode 16.4 Here is the test project: https://github.com/rezo0L/animation-issue-demo Any kind of support is appreciated

Hi Eduardo, If you're comfortable doing so, can you send the exact code you're using to run inference, either here or in a Feedback Assistant report to Foundation Models? I tried replicating the behavior from your YouTube video (very helpful by the way, thanks!) but I was not able to see this behavior in my Xcode and Instruments, running the same prompt as in your video. Incidentally, I noticed my tokenizer returns just 52 input tokens for the input: let instructions = You are a teacher. Today you talk about New Work City in USA. You must only answer questions about New York. let prompt= Talk about the statue of liberty ...which is significantly less than the 163 tokens in your video. Additionally, both with streaming and non-streaming, I see the input tokens are 52 and never change. This makes me suspect there might be something in your code that's triggering additional tokenization, but without seeing your inference code, I can't diagnose further. Thanks! - MB Researcher

I ran your program and didn’t see anything weird, at least on the local network privacy front. Specifically: I open the project with Xcode 26.1. In Signing & Capabilities I chose my individual test team. I tweaked the default IP address and port to match a server on my local network. I built the project. And copied the resulting app to a VM running macOS 26.1. Its network interface is in bridged mode, so it’s effectively on my local network. In the VM, I moved the app to Applications. And launched it from the Finder. I clicked Test Connection. It prompted for local network access, which I allowed. It was able to connect. I clicked Test Connection again, just to make sure it’s still working. I restarted the VM. I launched the app and clicked Test Connection. It continued to work. I see various possibilities here: It’s possible that something is borked on your specific test machine. I recommend that you re-test on a VM, as described above. (As mentioned in TN3179, VMs are a good way to test this st

Your answer is helpful. My previous question was strange because I didn't consider posting it in HTML. As a result, I wasn't able to properly communicate what I wanted to say. The symptoms I'm experiencing are as follows: With the following settings, the signing certificate status in Xcode shows as failed. IOPCIPrimaryMatch 0x00001916&0x0000FFFF The error message is as follows: doesn't include the com.apple.developer.driverkit.allow-any-userclient-access entitlement and doesn't match the entitlements file's value for the com.apple.developer.driverkit.transport.pci entitlement. With the following settings, the signing certificate status error in Xcode disappears, and building and driver installation succeed. However, the driver cannot be assigned to the device. IOPCIPrimaryMatch 0x00001916&0x0000FFFF To check for any minor errors in my work, I reverted to a sign to run locally environment and tried the following values. All errors disappeared, and my drivers and software worked correc

[quote='807223021, JimmyKwak, /thread/807223, /profile/JimmyKwak'] I’m developing a macOS application signed with a Developer ID [/quote] I recommend that you use Apple Development signing for day-to-day development. That’s true in general — see The Care and Feeding of Developer ID — but it’s especially important for NE sysexen because of the issue discussed in Exporting a Developer ID Network Extension.

This is an array. The values for that array are documented here. Apply these values as follows: For an appex, add the value corresponding to its provider type.

What version of Xcode are you using? What version of iOS/macOS/other OS are you building for? I tried it in Xcode 26.1.1 on macOS 15.7.2, targeting iOS 26.1 and it works fine, no errors. Here's a reduced version (that also works): var dateComponent = DateComponents() dateComponent.day = Int(200 / 80) let newDate: Date = Calendar.current.date(byAdding: dateComponent, to: Date.now)! print(newDate)
