I had the error Command LinkStoryboards failed with a nonzero exit code  and found that I was using a reference to a non-existent storyboard  I had recently changed the name of a storyboard file  so changing the reference from the  old  name to the  new  name solved it for me  You may not have exactly the same error as me  but an easy way to find a more detailed explanation of the error is to    Show the issue navigator  while the build time error is showing  Click the error   Then  you should see more about your error      I hope this helps  Please  I am aware that I am answering from experience of a different error than this question was asked about  but I believe this advice should help you conquer similar problems

I encountered this error when I was upgrading my project from Swift 4 to 5  I first updated all my pods to their latest versions  When I built  some pods showed this error   The following steps resolved this issue for me    Removed all pods from Podfile Executed pod install to remove all installed pods Executed pod deintegrate to remove support for CocoaPods Deleted Podfile lock and  xcworkspace from my project so no CocoaPods anymore Now my project is a pure Xcode project Opened my project from the regular  xcodeproj file Changed Swift Version of my project to Swift 5 Cleaned the project  cmd shift K  Quitted Xcode Restored all pods to my Podfile Executed pod install to reintegrate CocoaPods and add my pods Opened the project from the  xcworkspace file Cleaned and rebuilt Some old pods that were still using Swift 4 0   SlideMenuControllerSwift in my case  were set to Swift 5 0  caused  many build errors in their code  I corrected it back to Swift 4 0  by opening the Pods project and selecting its target  Cleaned again  rebuilt    Now I have only errors in my own project code related with difference in Swift version I made  My job now is to fix them

Since this issue looks to have dozens of possible solutions and the root cause could be very vague  I ll throw my situation into the ring  Half of my pods were failing with some sort of CompileSwiftSource failure  but only on archive  I was still able to build for device and simulator just fine  I tried a lot  if not all  of the solutions suggested here with no luck  One of the pods had a slightly different error before the CompileSwiftSource error so I went to updating and trying to fix that single pod  It was the Cache library for iOS which hadn t been updated in a while  There was a fork that resolved the issue with updating to Xcode 10 2 that I was able to update to and after that  all of the other issues took care of themselves  So look for a single outlier in your pods if you re getting a bunch of them erroring out and start there

This is a known issue with Swift 4 2 and Xcode 10   I found an article here that fixed it for me  https   github com Yummypets YPImagePicker issues 236  In short  go to your projects build settings  and add a user defined setting named SWIFT ENABLE BATCH MODE and set its value to NO   Previously  I tried each of the methods suggested here  rebuild  exit Xcode  clean and rebuild  purge Derived Data files    None of them worked   Once I added the user define build setting per the article  Swift then told me the true error   In my case  it was a missing    but it could be any number of problems

I got the same error when linking separate storyboards  The error   Command CompileSwiftSources failed with a nonzero exit code   is shown because I simply forgot to set the view controller inside the second storyboard that I am linking as  an initial view controller

User · Answer

Command CompileSwift failed with a nonzero exit code  This error happens when you are migrating your code from Xcode 9 to Xcode 10    It due to any class name is conflicting with existing apple classes  For Example  State  Event etc    So first change the class structure name if any existing in your code like  State  to  StateDetail  If Info plist is added in target  remove tick mark from it so it will not copy app bundle  Latest Xcode10 security reason     Select Info plist file and uncheck under  Target Membership  in right side Identity inspector    And build code again

For me this was to do with a constraint that I was removing at build time  Unticking Remove at build time fixed the issue  and I suspect the compiler had an issue determining the layout without it  The error code will mention which Storyboard is causing the issue
