x/mobile: load of a Go static library in iOS project result in swift api behavior change

[Gaal123]

What version of Go are you using (go version)?

$ go version
1.21

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

go env Output

$ go env
GOARCH=arm64
GOOS=ios

What did you do?

I was add capacitor support to my mobile SDK, while testing on iOS the application stop working, searching around bring me to this issue where they even create a complete example. In the end the analysis result in this comment where they report that loading a static GO library will result in standard swift behavior change:

without the GO dependencies this will print the path as reported by Apple documentation

let fileUrl = URL(fileURLWithPath: "")
print("fileUrl:'(fileUrl.absoluteString)'")
fileUrl:'file:///'

If a go library is loaded this snippet will print:
fileUrl:'file:///private/var/containers/Bundle/Application/[guid value]/testApp.app/'

Note capacitor is not needed for this behavior change, I've tested with a native swift app and I was able to reproduce the same behavior

What did you expect to see?

The print should always be the same

What did you see instead?

The print change

It seems that it's not an issue of golang but an issue of Foundation according to the comment mentioned aboved.

Hello @MakDon, the comment you posted also say "Presumably the initialisation of the Go runtime has this as side effect". I would like to exclude the possibility that the GO runtime do something that can be done differently that provoke this behavior change.

Hello, does someone have any update on this?
