B9MulticastDelegate

Multicast delegate is a delegate that can have more than one element in its invocation list.

Installation

Use Swift Package Manager or import manually.

你也可以使用 gitee 镜像。

Features

• NSHashTable free. It brings better performance and support for Linux.
• MulticastDelegate confirms Sequence, which means that lots of sequence features are available.
• Thread safe.
• Other delightful details, eg: error handling optimization, debug log optimization.

Background

I'm a big fan of the multicast delegate. I have "invented" and used it since 2014.

As Swift’s ABI is stabilized, it's time to move a Swift implementation.

But I cannot find a satisfied implementation everywhere. So I write one.

Alternatives

• jonasman/MulticastDelegate - Use NSHashTable. Operator overloading is not a good idea, in my opinion. It is not intuitive and reduces readability. API does not meet design guidelines (Omit needless words).
• elano50/MulticastDelegateKit - Use NSHashTable.
• Kevin Lundberg's - Generic type should not be AnyObject. API does not meet design guidelines (Omit needless words).
• Greg Read's - Missing duplicate check when adding. API does not meet design guidelines (Omit needless words). I dislike removing when invoking.
• Ivan's - Missing duplicate check when adding. It is odd to use an equatable weak wrapper to check duplicates.
