[swift-users] Swift Package Manager (SPM) Deployment Target

Thanks for all the help so far everyone. I’ve now been able to successfully compile an example command line tool with Alamofire using `--xcconfig-overrides` flag and an .xcconfig file. However, I’ve run into one issue and have an additional question.

The issue I’m hitting is that the project still has the `MACOSX_DEPLOYMENT_TARGET` manually set (it’s bold) to `10.10` even though the xcconfig is loaded and has overridden it. If I delete the manual setting, the deployment target is set to 10.11 which is coming from the xcconfig file. While this is certainly nice, it may throw some people off at first when using this approach.

The second question I have is whether this type of override is planned for `swift build` or just for creating an Xcode project? My apologies if this has been answered in other threads, but I haven’t been able to track this down yet.

>> There isn't yet a builtin way to manage this. When generating an Xcode project, you can use the undocumented `--xcconfig-overrides` option to pass a path to an extra .xcconfig file you wish to include in the project and have build settings read from. You could then override the deployment target there.

From what I can tell, it is not currently possible to override it based on the source code itself. In the pbxproj().swift <https://github.com/apple/swift-package-manager/blob/master/Sources/Xcodeproj/pbxproj().swift#L73-L78> file, the MACOSX_DEPLOYMENT_TARGET is hardcoded to 10.10 with a FIXME saying it needs to be configurable.
