Query on NSLog

Sai_Kanduri · June 27, 2016, 11:37am

Hi All,

Currently NSLog has only one internal function NSLog() which can be used only by Foundation classes.Can this be made available as a public API ?

Thanks & Regards,

Hi Sai,

Out of curiosity, why NSLog instead of Swift’s print function?

I added NSLog for NSKeyedArchiver so the output formatting would more closely match Darwin, but I punted whether to make it public.

Frankly, I think I just forgot to put a stub for it when we put out the first set of APIs.

The Darwin overlay contains:

https://github.com/apple/swift/blob/master/stdlib/public/SDK/Foundation/Foundation.swift#L918
:
public func NSLog(_ format: String, _ args: CVarArg...) {
withVaList(args) { NSLogv(format, $0) }
}

So for consistency it would make sense to expose it on other platforms as
well.

OK, we should fix the function signature to make it identical then (currently it does not take an argument list), and perhaps define NSLogv() as well.

Agreed - being consistent is key. The Foundation Reference currently
documents the Swift API for NSLogv() as:

https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Miscellaneous/Foundation_Functions/#//apple_ref/c/func/NSLogv
func NSLogv(_ format: String, _ args: CVaListPointer)

If that's still correct, then I guess that's what we should be adding
