Build fails with “Command failed with a nonzero ex

Question

When I try to build my app with Xcode, an error interrupts the build process:

Command CompileStoryboard failed with a nonzero exit code

Sometimes, it shows this error instead:

Command CompileSwift failed with a nonzero exit code

I have New Build System turned on.

What can I do to fix this?

Answer 1

If you are facing an error like that on new MacOS version.

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

It means that you need to install XCode command line, open a Terminal and run this command:

$ xcode-select --install

In my case it was renaming a file to an existing file in other folder(Group) by mistake, just rename it to what it was then the error disappeared

Answer 3

This error happened to me when I forgot to change entity Properties before creating NSManagedObject subclass. Solved by:

1. delete Entity+CoreDataClass.swift and Entity+CoreDataProperties.swift.
2. under "class" of the entity model inspector, change "module" to Current Product Module and "codegen" to Manual/None.
3. recreate the NSManagedObject.

Answer 4

I had the JSONwebtoken pod installed and that was causing issues. I needed to delete the CommonCrypto folder that is in the JSONWebtoken pod folder. Here is a ->link<- explaining the issue. This started happening in Xcode 10.

Answer 5

I tried a lot of the options discussed here.

• Delete and reinstall pods
• Clean Build Folder
• Delete Derived Data
• Add SWIFT_ENABLE_BATCH_MODE and set its value to NO
• Restarting Xcode and Recompiling
• Restarting iMac and Recompiling
• set Compilation Mode to Incremental
• Changed build settings: SWIFT_COMPILATION_MODE = singlefile and SWIFT_OPTIMIZATION_LEVEL = "-O"

Nothing worked. I'm using Xcode Version 11.0 beta (11M336w).

Finally I downloaded a fresh copy and replaced the one I had previously installed. It was the same exact version. That did the trick.

I have faced similar problem. I have done

• clean project - didn't work
• Remove Derived Data Folder - didn't work
• Change build system to Legacy Build Settings - didn't work
• Restart XCode - didn't work
• Comment some of my code, a typedef NS_ENUM in .h file and enums related works. Build the system and build success shown. Next un-comment the code and build again - Magically works
