[swift-users] Help with swiftc target

Hello all,

I’ve been trying to use the ‘swiftc’ command from the version I built from
the source (build-script, swift-2.2-branch), and I am having problems with
the targets.

For example, I am able to use the command below just fine (which I believe
uses the swiftc I got with Xcode - version 2.1.1)

*$ xcrun -sdk iphoneos swiftc -target armv7-apple-ios8.0 *.swift*

But when I try to use it with my swiftc (version 2.2-dev), I receive an
error saying that it was unable to load a standard library for the target.
I also tried with the other targets at the end of the email.

*$ xcrun -sdk iphoneos
…/build/Ninja-DebugAssert/swift-macosx-x86_64/bin/swiftc -target
armv7-apple-ios8.0 *.swift*

*error: **unable to load standard library for target 'armv7-apple-ios8.0’*

It seems it is just working if I use the macosx sdk, but I wish to use the -sdk
iphoneos  or -sdk iphonesimulator to be able to import UIKit inside the
.swift file.

Do I have to build in a different way in order to use those targets? Or am
I doing something wrong? Maybe it has something to do with the contents of
the */Ninja-DebugAssert/swift-macosx-x86_64/* folder?



The build-script log showed multiple targets.
