Could not build the precompiled application for the device.

It appears that your application still contains the default signing identifier.
Try replacing 'com.example' with your signing id in Xcode:
  open ios/Runner.xcworkspace

Error launching application on  xx的 iPhone.

I guess this is related to libstd++. Which version of Xcode are you using? Can you show this section of from Build Settings?

[Wuzo]

我想这与libstd ++有关。您使用的是哪个版本的Xcode？你能从Build Settings中显示这一部分吗？

谢谢 确实是这个原因.
