Command ... swiftc failed with exit code 1

I have been stuck with this error for a while and none of the solutions I have found seem to work (at least in my case). Here is the complete error log:

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1

What I have tried:

  • Clean up the project

  • Comment on my recent changes

  • Create a new project and submit the code

When I create a new project, this error goes away, but I get another one saying there is an implicit entry point in main

. Searched the whole project for the main function but nothing came up. All my code is here if used.

Try using it xcodebuild -project ***.xcodeproj -scheme ***

, it will give you more details about the error.



For me it was added [unowned self]

to a block within a block.

In my case, this code throws an error:

processBtn.setTitleColor(.whiteColor(), forState: .Normal)

But if I add a UIColor, everything is fine:



processBtn.setTitleColor(UIColor.whiteColor(), forState: .Normal)

Perhaps you have similar errors in your code.

For other people who have this problem now. Please return previously deleted files to the system.

Your project may still reference this file somewhere in your project.
