Swift snippet #5 — Generic Typealias

Friday, 2nd December, 2016

In Swift 3 now that we can have generic typealiases, I use the above snippet quite often which declares a closure of a generic type (which could be any object you want) with void return type. We can use it in the following way which make things quite readable and easy to use 🚀:

let intClosure: Closure<Int> = { intValue in
    ...
}
intClosure(10)
