What did you do?
Use "gomobile bind -target=ios" to build a xcframework library, used in Flutter iOS app.
What did you see happen?
When using Xcode 15.0(15A240d), os.Executable() returns “/var/containers/Bundle/Application/E80602C7-EFFB-4F1B-9FF8-FBA0E7E3DA76/Runner.app/Runner” as normal. All goes fine.
But with Xcode 16.2(16C5032a), os.Executable() panic with err “cannot find executable path”.
What did you expect to see?
os.Executable() should return executable path as before on Xcode 16.

Are you running on an iOS device, or in a simulator?
In the case that it cannot find the path, it should return an error cannot find executable path, but should not panic. Could you check if it actually panics? If so, could you provide a stack trace? Thanks.

@cherrymui I tested on physical iPhone, not simulator.
To be precise, it returns that error, not panic -- as following indicated.
https://go.dev/src/os/executable_darwin.go
The error in return blocks app's function.
Is that a known behavior on Xcode 16? or any workaround?

Timed out in state WaitingForInfo. Closing.
(I am just a bot, though. Please speak up if this is a mistake or you have the requested information.)

I don't know. I don't have a phone at hand to test this easily. Maybe @golang/ios maintainers know?
