'Failed to import bridging header'

[ewing21@2017-01-02]

Hi, I've been doing a lot of work to get Swift usable in a cross-platform way (Mac, iOS, Linux, Android, Raspberry Pi). I heard about this Windows port so I thought I would give it a try.

Using the prebuilt Visual Studio 2015 binaries for the command line swift and swiftc executables provided by the Swift for Windows page, I am able to build and run a trivial Swift program (e.g. print("Hello World").

So my next step is to use a bridging header. The way I'm approaching cross-platform is that I have a bunch of already cross-platform C libraries (e.g. SDL) which I bind to Swift. Then you can write cross-platform Swift code. But for this to work, I need a bridging header.

When I try specifying a bridging header, I get the error "failed to import bridging header".

Any ideas on how to get this working?

Thanks

Multithreading and Grand Central Dispatch supported?

Are there any differences compared to the mac compiler where multithreading is handled by GCD?

In other words: will all CPU cores be used for heavy-duty tasks or do you need to handle it yourself?

Can I use import?

Ex: "import Foundation"

Cannot make wx.Frame border fixed

Thank you for Swift for Windows! 😄

I was going through the source of SwiftForWindows and cannot make the window border fixed. I don't want it to be resizable. This line

var frame = wx.Frame(nil, wx.ID_ANY, "Swift for Windows 1.9", size: wx.Size(1000, 600), style: wx.DEFAULT_FRAME_STYLE & ~wx.RESIZE_BORDER)

has

style: wx.DEFAULT_FRAME_STYLE & ~wx.RESIZE_BORDER

but this is being ignored and the border is still resizable.

I have consulted this documentation page and cannot find any other way to fix this. Is this a problem with SwiftForWindows?

Cant compile the program

Whenever I compile the program there is an error occurred:the system can't find specified path "link" is not recognized as internal or external command.

DLL Missing problem

Hey, I have some DLL Missing problem after install SwiftForWindows which impeded me to open it.
The Missing DLL are as follows :

Each message alarm for one times, and do not have any Error Code.
Could you tell me what to do, Thanks! 👍

Unable to compile a simple Win32 application

I copy the winapi headers from tinycc and change typedef wchar_t WCHAR; into typedef __WCHAR_T__ WCHAR; in winnt.h.
Those codes are able to run directly but not able to be compiled into executable binary.

easiest way to get libswiftcore.dll

I have Swift For Windows 1.6 installed. I created a swift file with one line of code to test.
