Minimum deployment target issue on 10.12? about swiftshell HOT 5 CLOSED

Hi, I haven't upgraded yet myself but I'm installing 10.12 in a virtual machine now to test this. Which version of Xcode are you using? And which version of swift on the commandline?

from swiftshell.

XCode 8, XCode 8 command-line tools, Swift version 3.0 (swiftlang-800.0.46.2 clang-800.0.38)

I'm actually running the first or second version of the GM of Sierra, build 16A319 - this is a lower build number than the final release, but it won't pull any updates - I don't think this detail should matter.

I did make sure the Swift 3 branch was checked out before compiling.

@bryan3000000 Setting the minimum deployment target to 10.9 fixed the problem. I have no idea why.

Can you try the latest commit and see if it works on 10.12 as well?

That commit does appear to have fixed the issue on 10.12. I second your confusion, and would not have thought to do that. In fact, I had forgotten to add that the import was working just fine as long as you were running swiftshell directly from the command line (as REPL) rather than in a script.

The only difference I can see is that the compile size is slightly larger with the deployment target set to 10.9. I assume this difference would be explained by the extra plumbing needed by 10.9 to run Swift. Maybe there's an issue in Swift 3 that the 10.9 compatibility works around.

It seems like a bug, but I have not been able to find much information on it. I also got the same problem on macOS 10.11.
