@mikeooye can u follow example? I used the iPhone device, all looks good

[mikeooye]

Sorry，I just saw your email. I missed a condition, you should run the example in release mode.

https://github.com/dart-lang/native/issues/897 I added dummy method to avoid swift optimisation, I verified in profile, it should work from 0.5.0
