Dear all,
I have written a screensaver , but unfortunately, I didn't have the time to

I’m writing a coreData helper which will rely on Generics.
Could I get some input?
I have synthesized the problem down to this somewhat nonsensical code.
From Playground:
func intFor(s:String) -> Int {
return Int(s)!
}
func genericIntFor(s:String) -> T {

Oops… I should have called it genericTfor etc as in:

I'm finding it a bit cumbersome to use CGFloat in graphics code in Swift,
because the compiler won't let me pass a floating-point literal to a parameter
that takes a CGFloat. I have to wrap them all in CGFloat().
This seems really, well, cumbersome. Why does the language impose this burden?

Don’t use Scripting Bridge for this. Since 10.9 there’s MLMediaLibrary and
related classes which provide access to various media, including iPhoto and
Photos content.

Sorry, it’s been a long day :-)
I am really trying to understand this. So….. given this… and I think this will
make sense now,

Also weird, I only have to cast the last two arguments, not the second.

The problem in this case is that M_PI is a Double variable in Swift, not a
compile time constant like in Obj-C. You will unfortunately have to wrap it in
CGFloat(), then the constants should work fine

At compile time there is no way of determining if T has an initializer that
takes a string. You could do something like this

Point taken.
This was just a “trivial” … well it seems not that trivial…example to deepen my
understanding of Generics. So, I thank you, and will repost with a more
specific example if and whe

No, it’s a numeric literal, so it has no numeric type. However your ‘addArc’
function requires CGFloat parameters. Literal 0.0 is convertible to CGFloat,
but Double M_PI isn’t convertible automatically.

That’s bridged, not converted. :)
The Swift compiler has built-in knowledge of what can be bridged, and does a
typecast or value conversion according to context.

I’m guessing this is only a problem when building 32-bit? Because in 64-bit,
CGFloat is equivalent to Double, so there shouldn’t

Slightly off topic; I would love to see some form of what Scala calls
implicits in swift. For exactly this reason.
