Update to XCode 8.3.1: Apple Mach-O Linker Error Group with Snapkit error

Question

Just updated to Xcode 8.3.1 and build my project get the errors like:

 "__TFE7SnapKitPS_23ConstraintAttributesDSLg6heightCS_14ConstraintItem", referenced from:

  "__TFE7SnapKitPS_23ConstraintAttributesDSLg5widthCS_14ConstraintItem", referenced from:

  "__TFE7SnapKitPS_23ConstraintAttributesDSLg6centerCS_14ConstraintItem", referenced from:

  "__TFE7SnapKitPS_23ConstraintAttributesDSLg7centerXCS_14ConstraintItem", referenced from:

  "__TFE7SnapKitPS_23ConstraintAttributesDSLg6bottomCS_14ConstraintItem", referenced from:

  "__TFE7SnapKitPS_23ConstraintAttributesDSLg7leadingCS_14ConstraintItem", referenced from:

  "__TFE7SnapKitPS_23ConstraintAttributesDSLg7centerYCS_14ConstraintItem", referenced from:

  "__TFE7SnapKitPS_23ConstraintAttributesDSLg8trailingCS_14ConstraintItem", referenced from:

  "__TFE7SnapKitPS_23ConstraintAttributesDSLg3topCS_14ConstraintItem", referenced from:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Seems it's SnapKit issue.

• Tried cmd + shift + k
• Removed pod 'SnapKit' pod install and added it back still not work.

If it's not version issue. How to debug/solve these kind of errors. Thanks.

EDIT Right click the error in project navigator, then choose Reveal in Log show more error information:

Undefined symbols for architecture x86_64:
  "__TFE7SnapKitPS_23ConstraintAttributesDSLg6heightCS_14ConstraintItem", referenced from:
      __TFFC6Auroma22AURAlarmViewController19configureBottomViewFCSo6UIViewT_U2_FC7SnapKit15ConstraintMakerT_ in AlarmViewController.o

I can see AlarmViewController called SnapKit layout methods. But still not clear why the error were there.

EDIT My previous Xcode should be 8.3.

Finally solved by removing ~/Library/Developer/Xcode/DerivedData.
