Your go version says amd64 but your output says arm64
Please clarify whether you set GOOS and GOARCH

Also is there a reason you are not using golang.org/x/mobile ?

Thank you so much！
I'll try it.

already fixed

[jaroslavas]

So how have you fixed it?

[wuhan005]

So how have you fixed it?

I switch my Go version from go1.16.x to go1.14. Then it works.

That's not working for M1 MacBooks tho - any suggestion on how to fix it?

go version go1.16.5 darwin/arm64

I know it's been almost a year ago but.. :)
have you managed to fix it?

ping same-zeezes

Getting this here too.

Adding -tags=ios to go build causes the unresolved linker errors to go away but then there's a crash on startup.

If anyone gets any insight into this, please post -- thanks.

[drew-512]

I figured out the issue was I was using GOOS=darwin rather than the more recent GOOS=ios (since go 1.16?)
