@PedrinhoDS, Can you share a video recording of it ?
@desusai7 sure, this build is from Xcode 16, but I also faced the same issue when I ran from Xcode 15.4
https://github.com/user-attachments/assets/1ef1b885-aff8-49ab-8762-10eb991d7963
@PedrinhoDS, were you facing this issue on a real device as well ?
We had also observed minor ui inconsistency issues happening only on simulator.
And were you using any new options in safari like hide distracting items ?
So, I just tested it on a physical device (iPhone 14 Pro Max), and it worked as expected. I think it may be happening only on simulators.
Regarding the new options in Safari, I'm using a fresh simulator; I didn't change any configuration there
I see, can you check if this issue is happening for you on simulator when using SFSafariViewController as the user agent ?
You can follow the steps here on how to configure SFSafariViewController as the user agent.
Just got this crash and it may have something that may be helpful for you.

@PedrinhoDS, Can you share the steps to reproduce this crash, and did this crash happen on simulator ?
So, I just built the app with this configuration and opened the web auth dialog, as soon the dialog loads, I get the crash
_ = try? await Auth0
.webAuth()
.provider(WebAuthentication.safariProvider())
.audience("audienceurl")
.useHTTPS()
.start()
And the crash happens only on the simulator
Do you have associated domains configured and was this issue happening for you on real device as well ?
Yes, I do have associated domains configured, and no, its only happening on simulators
The issue seems to be something related to simulators running on iOS 18, we will investigate this, thank you for reporting this and sharing all the information swiftly.
Hi, I have the same issue on iOS 18 simulator with the Flutter package. Everything is fine on the same simulator device, iOS 17.5.
Hello,
I'm having a similar issue on the iOS 18 simulator with the React Native Package. Everything is fine on a real device and/or an older iOS version. Once a webauth session is initiated, this is the login screen...
After some time, the actual Macbook reports that the SafariViewService has exited.
Thanks.
Happy to provide more information if that would be helpful!
I too am running across this issue. The only work around is to disable my local VPN. This is happening when I am on Xcode 16, not 15.1.
Hi, I am also having the same issue. How can we solve it?
Hello, I am having the same issue, I have 2 projects, one using the react-native-auth0 package, Same issue on both of them.
@desusai7 Is there an update to this issue?
We noticed that emulators are now working on iOS 18 with Xcode 16 running. No updates to the Swift SDK have been made (running v2.9.0), and no tenant updates performed.
Anyone else also seeing this fixed?
Bug on - iOS 18, Xcode - 16.
I am using Auth0 - 2.0.0 SwiftUI Native iOS application.
I am not even getting SSO alert to login
getting error -
Attempting to load the view of a view controller while it is deallocating is not allowed and may result in undefined behavior (<SFAuthenticationViewController: 0x7fa958926a00>)
Then i remove .useHTTPS() after that i am getting blank page and app become unresponsive on iOS simulator, but running fine on physical device.
Hi everyone,
The iOS simulator issue seems to be fixed on the 18.2 simulator:
https://github.com/user-attachments/assets/4d1d685e-7947-443e-8cf2-1a084d9aa2a9
Whereas it is present on the 18.1 simulator:
https://github.com/user-attachments/assets/94c5ef57-ab2a-40cf-9628-24855d69aca3
Closing as it's a simulator issue that's now been fixed.
