<body><div>I assume that a lot of this stuff is coming. However, based on the current state of things, I'm actually really surprised we don't have a Package.lock file (or equivalent). Being able to reproduce the exact build on multiple machines or at multiple points in time is really important. I may specify that I want version 1.x of a package but everyone who checks out my project and builds it should get the exact same version (e.g. 1.0.2) of the dependency, even if there's a newer compatible version.<br></div>

<div>It seems currently there is no way to update a dependency to a compatible version unless we remove the cloned dependency folder from Packages manually.<br></div>
<div> </div>
<div>Take example, consider the Package.swift file as follows:<br></div>
<div> </div>
<div><div>let package = Package(<br></div>
<div> name: "Dealer",<br></div>
<div> dependencies: [<br></div>
<div> .Package(url: "<a href="https://github.com/apple/example-package-deckofplayingcards.git">https://github.com/apple/example-package-deckofplayingcards.git</a>", majorVersion: 1),<br></div>
<div> ]<br></div>
<div>)<br></div>
</div>
<div> </div>
<div>It will clone and build the latest 1.x.y (currently 1.0.2, <a href="https://github.com/apple/example-package-deckofplayingcards/releases">https://github.com/apple/example-package-deckofplayingcards/releases</a>) for me. Let’s assume later a new compatible version 1.0.3 is released. However, even I run `swift build` again, it seems the package manager will not update this dependency, since the existing version is already match the requirement. ( <a href="https://github.com/apple/swift-package-manager/blob/master/Sources/dep/get.swift#L260-L270">https://github.com/apple/swift-package-manager/blob/master/Sources/dep/get.swift#L260-L270</a> ).<br></div>
<div> </div>
<div>Even I run a `swift build -k` before building the package, the dependency wouldn’t get updated. The only way to update to a most recent compatible version seems to be a `rm -rf Packages` before build.<br></div>
<div> </div>
<div>As I specified the major version should be 1, IMO, it means I may want the latest version before 2.0.0. Is current behavior expected, or is there any plan to provide a better way to upgrade the dependencies? Maybe we need some options like `swift build —clean_all` or `swift build upgrade`?<br></div>
