 Comment 0: I saw this error yesterday too when I tried to use Carthage to install SQLite.swift as a dependency of my project.

I was able to get SQLite.swift to build if I installed manually and used Command-B to initiate the build.

 Comment 1: did it's work, can you tell me you step ?

 Comment 2: Can you retry with the latest instructions? 
 Comment 3: I am using Xcode 8.0.

I changed my Cartfile line from what was in the old SQLite.swift readme

    github "stephencelis/SQLite.swift" ~> 0.10.1

to what is now in the new SQLite.swift readme

    github "stephencelis/SQLite.swift" ~> 0.11.0

and then the build initiated by `carthage update` did succeed.

I did see a screenful of warnings at the end of the build that were like

    <module-includes>:1:1: warning: umbrella header for module 'SQLite' does not include header 'sqlite3.h'

After following the Carthage instructions for [Adding frameworks to an application](https://github.com/Carthage/Carthage#adding-frameworks-to-an-application),  I can now `import SQLite` in my `AppDelegate` file and building my project succeeds.
 Comment 4: Closing

 Comment 5: I have my project written in Swift 2.3 and I cannot use 
`github "stephencelis/SQLite.swift" ~> 0.11.0 `

When I use 
`github "stephencelis/SQLite.swift" ~> 0.10.1`

I get the same above error.
