Hello everyone,

I’m running into an issue where a partial sheet repeatedly presents and dismisses in a loop.

Setup

The main screen is presented using fullScreenCover
From that screen, a button triggers a standard partial-height sheet
The sheet is presented using .sheet(item:)

Expected Behavior

Tapping the button should present the sheet once and allow it to be dismissed normally.

Actual Behavior

After the sheet is triggered, it continuously presents and dismisses.

What I’ve Verified

The bound item is not being reassigned in either the parent or the presented view
There is no .task, .onAppear, or .onChange that sets the item again
The loop appears to happen without any explicit state updates

Additional Context

I encountered a very similar issue when iOS 26.0 was first released
- At that time, moving the .sheet modifier to a higher parent level resolved the issue
The problem has now returned on iOS 26.4 beta
I’m currently unable to reproduce this in a minimal sample project, which makes it unclear whether:
- this is a framework regression, or
- I’m missing a new presentation requirement

Environment

iOS: 26.4 beta
Xcode: 26.4 beta

I’ve attached a screen recording of the behavior.

Has anyone else experienced this with a fullScreenCover → sheet flow on iOS 26.4?

Any guidance or confirmation would be greatly appreciated.

Thank you!

Hi, did you find a solution to this problem? I am experiencing a similar issue in my app on 26.4.

I present a sheet from a fullScreenCover and the sheet just gets instantly dismissed. On 26.3 it works.

Regards,
