This is incorrect. swift-lang.org is a completely unrelated language that happens to be called Swift. The official site for Apple’s Swift is swift.org. --  Paul Schifferer Sent with Airmail On March 18, 2016 at 10:53:48, Ramakrishna Mallireddy via swift-users (swift-users@swift.org) wrote: swi

Re: [swift-users] Swift on a cluster?

swift-lang.org is official website for Apple Swift Language. C, ObjC , C++[need to write C/ObjC wrapper] libraries can be used with swift code. The swift compiler currently works on mac & linux. On Fri, Mar 18, 2016 at 10:42 PM, Graymalk Meow via swift-users < swift-users@swift.org> wrote: > Hi

Hi Jon, You are right that this is a limitation of the current implementation in Swift 2.2. I may have fixed this recently in master: https://github.com/apple/swift/commit/3aacf5d805768527b59d24e6da2a03911b3dd5b0

Re: [swift-users] Installing Package manager

The swift in /usr/bin does not know about the swift toolchain you have installed. You need to add the swift from the /usr/bin in your toolchain to the PATH first. Once Xcode 7.3 lands you’ll be able to set TOOLCHAINS=swift as an environment variable and then you won’t need to set the PATH. >
