JustSignals

JustSignals is a type-safe alternative to NotificationCenter and delegates. Use it if you don't need binding and rx magic in your project, and just want to replace NotificationCenter with something more strict and safe. Otherwise take a look at RxSwift, ReactiveCocoa and Bond.

# Podfile
use_frameworks!

target 'YOUR_TARGET_NAME' do
    pod 'JustSignals'
end

Replace YOUR_TARGET_NAME and then, in the Podfile directory, type:

$ pod install

Add this to Cartfile

github "devandsev/JustSignals"

In the Cartfile directory, type:

$ carthage update

Signal without any data:

let signal = Signal<Void>()
signal.subscribe(with: self) {
    print("pong")
}

signal.fire(())

Signal with data:

let signal = Signal<Int>()
signal.subscribe(with: self) { data in
    print(data)
}

signal.fire(36)

If you need to pass multiple values:

let signal = Signal<(Int, Float, String, Bool)>()
signal.subscribe(with: self) { data in
    print(data)
}

signal.fire((3, 2.2, "test", false))

Subscription cancels automatically if the object that has been subscribed to the signal is deallocated, but if you need to unsubscribe early, use this:

signal.unsubscribe(self)
