FormulaStyleDate

Formula-style NSDate calculation framework for Swift.

Code Examples

import Foundation
import FormulaStyleDate

let now = NSDate()
let before = now.dateByAddingTimeInterval(-60.0)
let after = now.dateByAddingTimeInterval(60.0)

now + 60.0 == after  // => true
60.0 + now == after  // => true

now - 60.0 == before // => true
now - before == 60.0 // => true

now < before // => false
now < after // => true

now > before // => true
now > after // => false

now <= before // => false
now <= now // => true
now <= after // => true

now >= before // => true
now >= now // => true
now >= after // => false

Please refer to the code for the test case, too.

Requirements

• Swift 1.2 (Xcode 6.3 or later)
• iOS 8 or later (by Carthage) / iOS 7 (by coping the source files directly)

Installation

There are two options.

Using Carthage (iOS 8 or later)

Using Carthage, it's easy to add FormulaStyleDate to the project.

• Add github "fhisa/FormulaStyleDate" to your Cartfile.
• Run carthage update
• Add FormulaStyleDate.framework in Carthage/Build/iOS to your Xcode project.

Copying source files directly (iOS 7)

• Add this repository as a git submodule:

$ git submodule add https://github.com/fhisa/FormulaStyleDate.git PATH_TO_SUBMODULE
// or
$ carthage update --use-submodules

• Then just add references of FormulaStyleDate/*.swift to your Xcode project.

TODO

• CocoaPods support
