Re: [swift-users] Localization in Swift.

Hello everyone. Thanks to you all for replies in this thread. I am currently working on a Xcode Extension for this purpose. I would like to bring it to github in this week. This will be my first Xcode extension, also my first github open sourced project. Zhaoxin On Thu, Nov 3, 2016 at 6:14 AM,

Re: [swift-users] Element vs. Iterator.Element

I don’t remember the details, but IIRC ‘Iterator’ is an inferred associated type on Array, so it cannot appear in the ‘where’ clause of an extension. This is a known limitation of the name lookup code — presently it cannot recur into associated type inference due to circularity. We plan on addre

The only real way to do this today is to have two layers of protocol: protocol SpecialControllerBase { var currentValueBase: SpecialValue? { get } } protocol SpecialController: SpecialControllerBase { associatedtype SpecialValueType : SpecialValue var currentValue: SpecialValueType? { get }

Hi, In the following code, I want to test if x is a `SpecialController`. If it is, I want to get the `currentValue` as a `SpecialValue`. How do you do this? If not with a cast, then some other technique. I understand the error, and that SpecialController by itself is not a simple type to cast

So there are issues we have in swift-corelibs that suffer(leak) because we don't have ARPs on Linux. It would be super nice to have a retain until scope end concept for swift core libs where autorelease would be an accessor in unmanaged that would retain the object until the arp ends scope. Sen
