in iOS26.4, after installing the app for the first time, opening the app and clicking on the UITextField input box will trigger the system to pop up the network permission application interface.
This issue did not exist before iOS 26.3, only in iOS 26.4. This is a fatal bug where the network permission request box should not pop up when the developer has not called the network related API.
I reported it as FB22333352
Thanks. That’s definitely the right path forward for this.
IMPORTANT I noticed that you didn’t attach a sysdiagnose log to your bug report. Even though this problem is easy to reproduce, a sysdiagnose will help with the routing of your issue internally. So please reproduce the problem, trigger a sysdiagnose log, and then attach it to this bug.
For more information about sysdiagnose logs, see Bug Reporting > Profiles and Logs.
For context, that alert says:
允许 “testNetwork”使用无线
数据？
关闭无线数据时，部分功能可能无法
使用。
[无线局域网与蜂窝网络]
[仅限无线局域网]
[[不允许]]
A machine translation is:
Allow "testNetwork" to use wireless data?
When wireless data is turned off, some functions may not be available.
[Wireless LAN and Cellular Network]
[Wireless LAN only]
[[Now Allowed]]
This alert only shows up if the iPhone was bought in China, where iOS gives the user the option to control an app’s access to Wi-Fi (normally the user only gets the option to control access to WWAN). See this post for a little more detail about this difference in behaviour.
Still, this is definitely annoying and certainly not caused by your code, and hence your bug report makes sense.
Share and Enjoy
