After updating to Xcode 9.3 I am not able to compile my project. Where as compiling the same code on earlier version of xcode it works.

After lot of investigation i found that there are few functions like in below error -

1.  Running pass 'Function Pass Manager' on module '/Users/ankitnigam/Library/Developer/Xcode/DerivedData/Milq-cywzubaffxgpwaeipfxgtfswiuxo/Build/Intermediates.noindex/Milq.build/Debug-iphoneos/BN Beta.build/Objects-normal/arm64/AnswerViewController.o'.
2.  Running pass 'Prologue/Epilogue Insertion & Frame Finalization' on function '@_T04Milq20AnswerViewControllerC28didTapOverFlowMenuOpenrationyAA0ghI10OperationsO13menuOperation_tF

func didTapOverFlowMenuOpenration ()

once i make change to this function in the class error pointed to, code compiles but same function in other class does not give any compilation error.

tried all solution from this - Already asked question

Have you tried a clean build? Also, what exactly is the error? – Palle Apr 04 '18 at 18:49
What is the entire crash log? – staticVoidMan Apr 04 '18 at 19:02
@staticVoidMan too long to put here. – the monk Apr 04 '18 at 19:54
@Palle Yes i cleaned the derived data many times. There is no specific error in code, but while compiling the code in the error log i get above stated 1 and 2 point listed. – the monk Apr 04 '18 at 19:56
Try to strip down a copy of your project to a minimal reproducible example and then post the code here. – Palle Apr 04 '18 at 20:53

I was able to compile my code with Xcode 9.3 if I change the Swift Compiler Optimization level to [-O] (Optimize for speed), But not sure why it worked and Why it didn't if Optimization level was [-Onone] – the monk May 23 '18 at 07:11
Updating to Xcode 9.4 fixed it. – the monk Jun 28 '18 at 18:42
