Procedure

Swift 4, SPM

Simple wrapper around NSOperation to allow operation chaining.

Usage

Procedure<Void, Bool>(executeOn: queue, { (_, fullfill) in
            Thread.sleep(forTimeInterval: 0.3)
            fullfill(true)
        }).then(Procedure<Bool, Int>(executeOn: queue, { (op1Result, fullfill) in
            Thread.sleep(forTimeInterval: 0.3)
            fullfill(op1Result ? 1 : 0)
        })).finally { (result) in
            // Do something with the result from previous procedure
        }

TODO:

• improve chaining performance when there are a lot of operations in queue
• iOS xcodeproj
• add sugar and improve interface and comman usages
• travis
