What? The docs say that substringToIndex is declared like this:
func substringToIndex(_ to: Int) -> String
So, why can't I call that here:
extension
NSURL
{
func
normalizedURLByAppendingPathComponent(var inComponent : String)
-> NSURL
{
var s = self.absoluteString;
if s.hasSuffix("/")
{
s = s.substringToIndex(s.characters.count - 1)
}
if inComponent.hasPrefix("/")
{
inComponent = inComponent.substringFromIndex(1);
}
s = s.stringByAppendingString("/");
s = s.stringByAppendingString(inComponent);
let u = NSURL(string: s);
return u;
}
}
