CoreEvents
Small Swift events kit that provides some base types of events:
FutureEvent
Simple event. Provides classic behaviour.
Description
This is classic event (like C# event) that can contain many listeners and multicast each new message for this listeners. This event emits only new messages. It means if you add a new listener to existed event then last will not emit previous messages to the new listener.
Types
FutureEvent: Event
Example
var event = FutureEvent<Int>()
event += { value in
print("Awesome int: \(value)")
}
event.invoke(with: 42)
will print Awesome int: 42
PresentEvent
Description
This event provides all Future logic, but additionally provides emiting last emited value for a new listener. It means if your event already emits value and you add a new listener then your listener handles previous emited value in the same time.
Types
PresentEvent: Event
Example
var event = PresentEvent<Int>()
event += { value in
print("Awesome int: \(value)")
}
event.invoke(with: 42)
event += {
print("Old awesome int: \(value)")
}
will print:
Awesome int: 42
Old awesome int: 42
PastEvent
Description
This event is like the Present, but emits all previous messages for a new listener
Types
PastEvent: Event
Example
var event = PastEvent<Int>()
event.invoke(with: 0)
event.invoke(with: 1)
event += { value in
print("Awesome int: \(value)")
}
event.invoke(with: 2)
Will print:
Awesome int: 0
Awesome int: 1
Awesome int: 2

pod 'CoreEvents', '~> 2.0.1'
We also support SPM:
.package(url: "https://github.com/surfstudio/CoreEvents", .exact("2.0.2"))
Warning
In one file you can not use just add, you should specify a key - add(key: String, _ listener: Closure)
Versioning
Version format is x.y.z where
- x is major version number. Bumped only in major updates (implementaion changes, adding new functionality)
- y is minor version number. Bumped only in minor updates (interface changes)
- z is minor version number. Bumped in case of bug fixes and e.t.c.
