How to make my app alive to make the second queue finish its job? What I want
is:
- start program- start an external process from a thread (asynchronously)-
start another thread after 5 seconds to terminate the process from the other
thread- end program
That's all.

It looks like you aren't keeping your app alive to allow the secondary
queue to reliably execute the closures you queue with it. It isn't really
clear what you want to attempt so it hard to suggest the correct way to do
things.

Hi all,
I'm currently still learning Swift 3. Now I'm playing around with GCD (grand
central dispatch). I'd like to start an external process using Process from an
asynced thread, and create another thread to stop that external process after
some times. Here's what I do…
import Foundationimport
What is your real question?
Obviously the doc says that this is fine, so what are you asking? what is your
problem?

Rien

I am having trouble using this C API due to use of some build defines, but I
could be doing it wrong.
Current trying to compile a test it on macOS with the following modules.map:
module CFuseLinux [system] {
header "/usr/include/fuse.h"
link "fuse"
export *
}
module COSXFuse [system
Yes, it does seem to work. I just wondered if there was a better way to do it.
Perhaps by writing the method in a base class (but I couldn't get that to work)
instead of using an extension. Then I could just inherit from that base class
rather than needing to write:
extension Event: DDRCoreData
Hello,
Is getResourceValue a method or URL or only on NSURL?
After migrating a project to Swift 3 I have code like
var file:URL
file.getResourceValue(...) // compiles!

TIA,

Hello,
It looks that you have what you wanted because Event.Entity is an alias of
Event.

Hi All.
I think this is a case of ambiguity that the compiler is not catching at the
call site. Consider this example:
private class DefaultValues {
// If this method exists, it compiles and it called.
// If this method does not exist, the code in the test says, "Ambiguous use
of '

I simplified your example package and posted a bug report here:

I wonder why the description method of collections use the debugDescription
method to print their elements, and not the description method.
Dmitri Gribenko gave this reason in December 2015 [1]:
Array's description shouldn't be presented to the user in raw form,
ever, so the use case here is

Hi Jens —
BinaryFloatingPoint is very deliberately limited to the arithmetic operations
required by IEEE 754. This is the minimal set of operations that a binary
floating point type should provide, but it's already a really large
implementation burden for someone who wants to implement their ow
Is there a way to make a static or class method specify the return type be the
actual class it is called with?
The example code below using protocols/extensions mostly works (the type is
[Event.Entity] not [Event] but it seems to work.
If I try to make DDRCoreData a base class and Event subclas
I wonder why the description method of collections use the debugDescription
method to print their elements, and not the description method. Example:
let s = "a\"b"
print(s) // a"b
print(s.debugDescription) // "a\"b"
let x = 1.1
print(x) // 1.1
print(x.debugDescription) //
The code below doesn't compile since there is no exponential function (exp)
that works on all FloatingPoint or BinaryFloatingPoint types, also no
protocol seems to define the power function or the constant e, although
they do define for example: basic arithmetic operators, squareRoot() and pi.
ext
Exactly.
I would only add that renaming might not be the correct solution in some cases
as, then, instances of the subclass would still be able to invoke the
superclass method and that might not always be acceptable.

I think there is a clear case for a warning here, in that the introduction of a
default parameter value in such cases is in effect an empty promise and just
introduces unreachable code. Indeed 'unreachable code' should perhaps be the
warning.
This is because as soon as there is a foo() method,
