Syntax sugar for unwrapping while throwing error for nil

With this syntax sugar you can unwrap variables while throwing error for nil. It’s useful in closures/functions with throw.

func unwrap<T: UnwrapProtocol>(object: T, _ error: ErrorType = default) throws -> T.Wrapped

let foo: Int = 3
let bar: Int? = 3

try unwrap(foo) // Compile error
try unwrap(bar) // OK

{ [weak self] in
    let _self = try unwrap(self)
}

operation
    .doOnNext { [weak self] i
        let _self = try unwrap(self)
        _self.value = "abc"
    }

Unwrap is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "Unwrap"
