Re: [swift-users] Simultaneous accesses, but modification requires exclusive access

Thanks a lot Hooman, I understand better now. The part that tripped me was the fact that value types would be copied every time. I didn’t realise I wasn’t making a copy of the value type in my program, the same instance of the value type was getting passed (as Quinn and you had pointed out).

Re: [swift-users] Extending 2D arrays of genetic type

You can do something like this: extension Collection where Element: Collection, Index == Element.Index { subscript(i: Index, j: Index) -> Element.Element { get { return self[i][j] } } } extension MutableCollection where Element: MutableCollection, Index == Element.Index {

Thanks a lot Zhao, using a serial queue works. So both the solutions works, thanks. > On 24 Jul 2017, at 5:39 PM, Zhao Xin via swift-users > wrote: > > You can use serial queue. > > class Car { > var helper = Helper() > lazy private var queue =

[swift-users] Extending 2D arrays of genetic type

I am trying to extend a 2D array, doing something like this: extension Array where Element == Array { } But this doesn't work ! Is there a way to do this ? Thank you ! :) Trevör ___ swift-users mailing list swift-users@swift.org

Re: [swift-users] Constraining the conforming type of a protocol

IMHO, there is a very subtle difference between : protocol Toggling : Equatable { … } extension Toggling { … } … and : protocol Toggling { … } extension Toggling where Self : Equatable { … } The first says that any type that implements Toggling also implements Equatable. The second
