Cannot install via carthage / Xcode 8.3.1 into Swift 3 Project

[tobhae-dev]

I added github "velikanov/SwiftPasscodeLock" to my cartfile
then I ran: carthage update SwiftPasscodeLock --platform iOS

I get:

The following build commands failed:
	Check dependencies
(1 failure)
** BUILD FAILED **c

In log file it says:

“Swift Language Version” (SWIFT_VERSION) is required to be configured correctly for targets which use Swift. Use the [Edit > Convert > To Current Swift Syntax…] menu to choose a Swift version or use the Build Settings editor to configure the build setting directly.

I think you must specify the SWIFT_VERSION in your Projects Targets to Swift 3 in Build Settings Tab.
Could you do that?

I just checked the SWIFT_VERSION in Projects Target and it was "Swift 3" already. I am not using Carthage so I can't really help here. Maybe @velikanov can check this

I have this exact same issue.

Xcode 8.3.1
Swift 3.1 (Can this be the problem?)
