error: The dependency graph could not be satisfied (https://github.com/jpsim/Yams.git)

[theladyjaye]

When trying to build with:

swift build -Xswiftc -target -Xswiftc x86_64-apple-macosx10.11

or

swift build -Xswiftc -target -Xswiftc x86_64-apple-macosx10.12

[theladyjaye]

It does download everything with:

.Package(url: "https://github.com/jpsim/Yams.git", Version(0, 2, 0)),

It doesn't compile however (obviously since 0.1.4 is the target dependency I would not expect 0.2.0 would)

Which revision are you using? I probably need to make a new tag. You need to use a commit after 73b018ee462c211bc8e22dcbde5dde73ddc38d96 which should resolve this issue.

same using master. and swift package generate-xcodeproj --xcconfig-overrides settings.xcconfig

Ok I just tried this on an macOS VM I made and replicate it locally now.

What is weird is that my usual dev machine doesn't have this problem. 🤔

SwiftPM AM I RIGHT!? 🤷🏻‍♂️🙋🏻‍♂️

I have the same issue :(

My guess is that you are not using Xcode 8.3 (I'm using Version 8.3 beta 3 (8W132p)).

$ sudo xcode-select -switch /Applications/Xcode-beta.app/Contents/Developer
$ swift package --version
Apple Swift Package Manager - Swift 3.1.0-dev (swiftpm-12078)
$ swift build -Xswiftc -target -Xswiftc x86_64-apple-macosx10.11

I'm going to update the requirements on the README to require Xcode 8.3 beta 3 (8W132p). After Swift 3.1 is released I'll start using branches to provide backward compatibility to older Swift (Xcode) toolchains.

Unfortunately, at the moment this project relies heavily on the latest SwiftPM; hopefully this stabilizes a lot in the future. My apologies for the instability.
