Re: [swift-users] XML parsing on Linux, with Swift 3.1

[Georgios Moschovitis via swift-users]

FWIW, I also prefer snake_case, but camelCase is unfortunately the standard 
convention in Swift so I use that.
Also, I avoid using libraries that don’t follow standard conventions.

Wow!
Need to brush-up my understanding of Swift ‘pointers’

Re: [swift-users] Custom operators from a module

[Howard Lovatt via swift-users]

Thanks Jordan. Turns out I had two problems:

  1. I had used ~> which is used in the library (but Xcode didn't tell me
about the redefinition).
  2. Once Xcode had decided that there was an error it wouldn't clear; but
when I quit Xcode and went back in it went away.

Thanks for your suggestion of logging a bug, reducing the problem to bug
form really helped.

Re: [swift-users] Custom operators from a module

[Howard Lovatt via swift-users]

I have a custom operator defined in a module and in my XCTest I import that 
module. In the tests the compiler says that the operator isn't defined. If I 
define the operator manually in the tests then it works. 

So what is going on?

Re: [swift-users] Custom operators from a module

[Jordan Rose via swift-users]

I just tried it myself with a framework and app target and it worked. Can you 
reproduce what you’re seeing in a simple project and file a bug report at 
https://bugs.swift.org  ?

Sorry for the trouble!

Re: [swift-users] Custom operators from a module

[Jordan Rose via swift-users]

It's actually the other way around: all operator declarations are exported from 
a module, all the time, even if the functions that implement them aren't. This 
is probably a model we should improve, but it's been that way since Swift 1.

Re: [swift-users] Writing a pod catcher for iOS

[Jeff Kelley via swift-users]

Incidentally, the book *iOS 10 SDK Development
* by Chris Adamson
walks you through building a podcast player. If you go to the linked
product page, you can even see some livestream captures on Vimeo for free
that cover a lot of this material.

[swift-users] Custom operators from a module

[Howard Lovatt via swift-users]

Hi All,

I am trying to use a custom operator imported from a module, unfortunately
you can't add public to the operators definition and therefore it isn't
exported from the module.

I can manually redefine the operator in the module where the operator is
used, but that isn't very satisfactory - is there a better way?

Thanks in advance,

  -- Howard.
