This framework is inspired by [Moment.js](http://momentjs.com). Its

objectives are the following:



- Simplify the manipulation and readability of date and interval values.

- Provide help when parsing dates from various string representations.

- Simplifying the formatting of date information into strings.

- Streamlining getting date components (day, month, etc.) from dates and

  time intervals.



Important: This framework supports iOS 9+, macOS 10.11+, tvOS 9+, watchOS 2+, Xcode 8 and Swift 3.



## Installation



SwiftMoment is compatible with

[Carthage](http://github.com/Carthage/Carthage) and

[CocoaPods](http://cocoapods.org/). With CocoaPods, just add this to

your Podfile:



```ruby

pod 'SwiftMoment'

```



SwiftMoment can also be used via the [Swift Package Manager](https://swift.org/package-manager/). 

Just add it to the dependencies in your Package.swift file:



```Swift

let package = Package(

    name: "MyPackage",

    dependencies: [

        ...

        .package(url: "https://github.com/akosma/SwiftMoment.git", from: "0.7.1"),

    ],

    ...

)

```



## Mac OS X Notes



- Drag the created .framework file into the Xcode Project, be sure to tick 'Copy Files to Directory'

- In the containing applications target, add a new 'Copy File Build Phase'

- Set the 'Destination' to 'Frameworks'

- Drag in the created .framework



## Examples



To use this library, just `import SwiftMoment` in your application.



To create new moment instances:



```Swift

let now = moment()

let yesterday = moment("2015-01-19")

```



By default, moments are initialized with the current date and time. You

can create moments for any... moment in the future or the past; you can

do that by passing strings in different formats:



```Swift

let yesterday = moment("2015-01-19")

```



You can also do it by directly specifying the components manually:



```Swift

let today = moment([2015, 01, 19, 20, 45, 34])

```



You can also use a dictionary with the following keys:



```Swift

let obj = moment(["year": 2015,

                    "second": 34,

                    "month": 01,

                    "minute": 45,

                    "hour": 20,

                    "day": 19

                ])

```



When using a `[String: Int]` dictionary, the order of the keys does not

matter. Moreover, only the keys above are taken into account, and any

other information is ignored.



There is also an extension to the `Int` type in Swift, used to create

`Duration` values directly from an integer value:



```Swift

let duration = 5.hours + 56.minutes

```



## Architecture



The two most important components of this library are the `Moment` and

`Duration` structures. `Moment` wraps an `NSDate` instance, while

`Duration` wraps an `NSTimeInterval` value.



Both `Moment` and `Duration` comply with the `Comparable` protocols, and

include all the required operators. In addition, `Moment` instances can

be subtracted from one another (which yields a `Duration`) and

`Duration` instances can be added to `Moments` to create new moments.



`Moments` and `Durations` are made as immutable as possible.



## Tests



Swift Moment includes a suite of tests showing how to use the different

functions of the framework.



To run the Linux tests in a macOS environment, please use the included Dockerfile:



```

docker build --tag swiftmoment .

docker run --rm swiftmoment

```



## Playground



A playground is included in the project to learn how to use the library.



## Differences with [Moment.js](http://momentjs.com)



- Format strings `DD` and `dd` do not yield the same results.
