But when I compile the swift file. I get this error: :0: error: unable to load standard library for target 'x86_64-unknown-windows-msvc'
Also, I'm able to fire Swift REPL but I when I declare a variable. I get this error:

@AbhimanyuAryan I would recommend that you carefully read over the instructions. I suspect that you are not using the toolchain correctly and missing flags. What is your exact invocation for the compiler?
I would expect something like this:
set SDKROOT=%SystemDrive%/Library/Developer/Platforms/Windows.platform/Developer/SDKs/Windows.sdk
%SystemDrive%/Library/Developer/Toolchains/unknown-Asserts-development.xctoolchain/usr/bin/swiftc.exe -sdk %SDKROOT% -I %SDKROOT%\usr\lib\swift -L %SDKROOT%\usr\lib\swift\windows ...
I'd like to be able to remove the extra -I and -L flags but unfortunately, I've been busy with other work.
The REPL requires additional flags to work. You should invoke it as:
I uninstall python 2.7 from control panel & now conda took over my system python with 3.7.5
I tried running swift command in terminal & it doesn't even fire REPL
Yes, lldb requires Python3.7 (which is part of Visual Studio), but should already be there I believe.
The errors are due to missing flags :). You must provide the SDK path (and currently an additional include and library search path which I hope to be able to remove, I think I have some ideas on that). In general, long term, your invocation should be something like:
That said, the integrated repl is not very well tested, I would recommend that you use the LLDB REPL (which requires that you pass in additional flags as I mentioned earlier).
The compilation errors you have not shared nor have you shared the compiler invocation so it is difficult to advise you on that.
It says %SDK_ROOT% system can't find it...I have already copy pasted this set SDKROOT=%SystemDrive%/Library/Developer/Platforms/Windows.platform/Developer/SDKs/Windows.sdk
Should i go in environment variable and create this manually ??
If you create the environment variable from the Settings panel, it will be persistent, if you set it from the console using set, it will be ephemeral.
%SDK_ROOT% is the wrong variable .. the variable was %SDKROOT% without the underscore. I would recommend that you ensure that the paths are correct, because it sounds like something is missing if those paths are not found.
@compnerd this is creating me the output file but how do I run this file? And this worked...I also want to use REPL like feature? Can you also paste command for that? you mentioned LLDB REPL...what command can fire that?
