same issue. Works on simulator, but not on the real device.

[petethepig]

Disabling bitcode worked for me

[khoango]

I face with same issue. Xcode version 8.3.3, golang 1.9.
Old version compile with golang 1.8 is ok

I set Bitcode same @petethepig but still error

--> update

I down to go 1.8.3, reinit gomobile, build and it work.

[remirobert]

@khoango I managed to fixed that for go 1.8, but I have the same issue for the 1.9

[dzwicker]

Hi, the setting for bitcode is gone in xcode 9!

[eliasnaur]

Is this a problem still? I regularly run gomobile bind apps from Xcode 9.2. The bitcode setting is not gone.

[solua]

It's ok with golang 9.4 and latest gomobile version

[eliasnaur]

Thank you.
