// Note that despite the SwiftConfig options for a given package (which should be
// very rare in practice), we still need to know the name of the swift module
// that this package relates to to properly understand import boundaries between
// projects/frameworks/modules.
//
// We do this by defining a file called "swiftmodule" that contains JUST the
// name of the Swift module at the root of your VDL packages. For example,
// if you have the VDL files for your Xcode project/target called UberForCats
// at /Users/aaron/uberforcats/vdl, then create
// /Users/aaron/uberforcats/vdl/com.uberforcats/swiftmodule and have it just contain
// "UberForCats". We then will treat any VDL files contained in that directory and
// any subdirectories as part of the UberForCats Swift module, ultimately letting
// the compiler and will automatically do the right thing if others import your package.
// If you don't do this then nobody will be able to import your VDL types in Swift,
// and you might end up with extra long class/pkg names (ComuberforcatsServicesProfit
// instead of ServicesProfit for $VDLROOT/com.uberforcats/services/profit).
//
// If you are creating multiple Swift modules for a given $VDLROOT then just place
// swiftmodule files at the logical boundaries. For eample, we do this for v.io/v23
// to be exported to the VanadiumCore framework, but everything under v.io/v23/services
// lives in the VanadiumServices framework.

	// WireToNativeTypes are meant for scenarios where there is an idiomatic Swift

var __VDLInitCalled bool

// __VDLInit performs vdl initialization.  It is safe to call multiple times.
// If you have an init ordering issue, just insert the following line verbatim
// into your source files in this package, right after the "package foo" clause:
//
//    var _ = __VDLInit()
//
// The purpose of this function is to ensure that vdl initialization occurs in
// the right order, and very early in the init sequence.  In particular, vdl
// registration and package variable initialization needs to occur before
// functions like vdl.TypeOf will work properly.
//
// This function returns a dummy value, so that it can be used to initialize the
// first var in the file, to take advantage of Go's defined init order.
