File download not working in Xcode 26.0 RC

Hello Apple Developer Community,

I'm experiencing an issue with file download functionality in the iOS Simulator after updating to Xcode 26 RC (Build 17A321).

Issue Description:

When attempting to download files in the iOS Simulator via Safari, the download prompt appears correctly, but after tapping the 'Download' button, files are not being saved to the Files app. The download appears to do nothing with no error message, no indication of failure, but the file simply doesn't appear in Downloads or anywhere in the Files app.

Environment:

  • Xcode Version: 26.0 RC (17A321)
  • iOS Simulator Version: 26.0 RC (23A339)
  • Device Simulated: iPhone Air

Steps to Reproduce:

  1. Open Safari in the iOS Simulator
  2. Navigate to a downloadable file (PDF, ZIP, etc.)
  3. Tap to initiate download
  4. Download prompt appears as expected
  5. Tap the 'Download' button
  6. Check the Files app → Downloads folder (empty)

Expected Behavior:

Files should download normally as they do on physical devices and as they did in previous Xcode versions.

Actual Behavior:

The download prompt dismisses after tapping 'Download', but no file appears in the Files app. No error message is shown, and there's no indication that the download failed, it simply appears as if nothing happened.

Additional Information:

  • Downloads work correctly on physical device (iOS 26 RC 23A340)
  • This functionality worked properly in previous Xcode versions

I have created a bug report to Feedback assistant: FB20190927

Thanks in advance for any assistance.

Thank you for taking the time to file FB20190927. One thing that would be helpful is if you could update that report with a sysdiagnose from the simulator after you reproduce this — you can trigger that with the xcrun simctl diagnose commands.

Here's another thread from a different forums account also reporting the same thing, just to help everyone find the different discussions about this.

Thanks for your reply, I've just attached a sysdiagnose file (simctl_diagnose_2025_09_12.08-17-25+0300.tar.gz) collected after I reproduced this behavior to the FB bug.
