Then: Installation with Carthage is broken

I’m getting same issue in iOS project. Xcode 9.2 Apple Swift version 4.0.3

github "devxoul/Then"

% carthage update --platform iOS Then
...
*** Downloading Then.framework binary at "2.3.0"
*** Skipped installing Then.framework binary due to the error:
	"Incompatible Swift version - framework was built with 4.0.2 (swiftlang-900.0.69.2 clang-900.0.38) and the local version is 4.0.3 (swiftlang-900.0.74.1 clang-900.0.39.2)."

Hey guys, I made a new release (2.2.1) which supports Xcode 9.1 🎉

Hey guys, I just updated the prebuilt binary of the latest release. Please check it again 😃

Is there any reason to use carthage update with --no-use-binaries option?

Using precompiled version is problematic even with Xcode updates. Xcode 9.1 uses Swift 4.0.2 and importing 4.0 binary is impossible.

Module compiled with Swift 4.0 cannot be imported in Swift 4.0.2

I removed Then.xcodeproj from the repository to manage the project only with Swift Package Manager. If you’d like to use with --no-use-binaries, can you try 2.1.1 instead?

Not to beat the dead horse here, but I just wanted to pop back in because I’ve been working to update some of my open source frameworks for the latest Swift version and consequently, the latest Swift Package Manager.

And O.M.G. … Swift Package Manager is a steaming hot mess.  I can’t even understand how anybody would consider this to be anything but Alpha-quality.  Package(…) arguments that change both in what’s allowed and in types allowed every year, dumb auto-assumptions that have no docs explaining them and no search results (i.e. if you have a .modulemap in your library’s base directory, the library is auto-assumed to be a system package, which is no longer supported), crap backwards-compatibility (many of my libs support Swift 3.0-5.1, but the swiftLanguageVersions: option no longer has an enum case for .v3), and much much more.

Long story short— no matter what you’ve read from who, Swift Package Manager needs a lot of work before it could even remotely be considered as an alternative to Carthage or Cocoapods.  Software maturity takes time & effort, and SPM is a malnourished infant.  My personal advice to every other dev reading this is: Don’t bother with Swift Package Manager.  I stand by what I said before— when Apple has decided that SPM is mature enough to be integrated into Xcode, it may be worth another look, but until SPM isn’t good enough for Apple’s Xcode team it isn’t good enough for me, and it shouldn’t be good enough for you either.

I’d prefer to keep this repository as simple as possible. Carthage requires extra work. (maintaining Xcode projects) It seems that Carthage is going to support SPM-only project from Swift 5 so we better wait for it 😃

That’s for both 2.1.0 and 2.3.0.

swift --version Apple Swift version 4.1.2 (swiftlang-902.0.54 clang-902.0.39.2) Target: x86_64-apple-darwin17.6.0

Xcode Version 9.4.1 (9F2000)

The same issue was on 2.3.0
