It seems like the only way is upgrading to Ubuntu 16.04 for now?

Thanks for the detailed info. I was able to reproduce this. There seems
to be some problem with importing modules without their swiftdoc in
Ubuntu 14.04. I've filed https
tall the Swift toolchain?
Also, can you post the output of:
$ swift build -v
Thanks!

Hi, everyone.
Installing swift on linux is not that easy. Following
https://swift.org/getting-started/#using-the-package-manager instruction,
but `swift build` failed:
```
error: manifest parse error(s):

hello all!
I'm wondering if somebody can explain following snippet to me.
protocol P {
associatedtype Element
func next() -> Element
}
protocol Q {
associatedtype T : P
func makeT() -> T
}
extension Q where Self.T == Self {
func makeT

How does Swift choose *rules* as you said?
Swfit encourage to override the property observer. But when we change
the own property in Child class's `didSet` observer, that would cause
infinite loop:
class Base {
t;base didset" and "child didset"
In Swift, as or as! won't change the instance's dynamic type. So it
does nothing. `type(of:base)` is still `Child`.

Hi all
It sounds convenient to monitor change in property's value using property
observer.
But TSPL(The Swift Programming Language) talk little about property
observer. There
are some questions abouts property observer.
1) when `didSet` observer will call?
I assume it's fine that changing
I am confused by the code snippet following:
func foo(_ value: Int?) {
// do nothing
}
let a: Int = 2
foo(a) // it works!
Why swift don't warn the type mismatch? I am woking on Xcode Version 7.3.1.
