#Semantic Versioning Twitter: @ajax64 Platform Platform License Travis

Semantic Versioning implementation in Swift! Use the struct Version to represent a version according to the Semantic Versioning Specification 2.0.0.

✔️ Fully Unit tested

✔️ 100% Swift

##Getting Started

Requirements

  • iOS 8.0+ / Mac OS X 10.9+
  • Xcode 7.0+
  • Swift 2.0

###Installation The easiest way to use SemanticVersion in your project is using the CocaPods package manager.

###CocoaPods See installation instructions for CocoaPods if not already installed

To integrate the library into your Xcode project specify the pod dependency to your Podfile:

platform :ios, '8.0'
use_frameworks!

pod 'SemanticVersioning'

run pod install

pod install

##Usage

Create version 2.0.0

let version = Version(major: 2)

Create version 1.2.3

let version = Version(major: 1, minor: 2, patch: 3) 

Create version 1.0.0-alpha.2

let version = Version(major: 1, preReleaseIdentifier: ["alpha", "2"])

Create version from a String

let version: Version = "1.3.10-rc"

Create a list of versions from a Array of Strings

let versions: [Version] = ["1.0.0-alpha", "1.0.0-alpha.1"] 

Check if is prerelease version or not

if version.isPrerelease { ... } 

Access the prerelease identifier via the preReleaseIdentifier Array

for identifier in version.preReleaseIdentifier
{
    // ...
}

Access the build metadata identifier via the buildMetadataIdentifier Array

for identifier in version.buildMetadataIdentifier
{
    // ...
} 

Conforms to Printable so you can simply get a String representation by accessing the description property

println(version)
// OR
let stringRepresentation = version.description

mutability / immutability

Comparsion

The default operators for comparsion are implemented < , <= , > ,>= ,== , != This will comapre major, minor, patch and the prerelease identifiers according to the Semantic Versioning Sepcification 2.0.0

##Parser

The implementation includes a full-fledged component ot parse String representation of a version. Please have a look at the tests and the soruce of SemanticVersioningParser for now 😉

##Tests

The libary includes a suite of tests showing how to use the different initialiser and the Parser

Travis CI is currently not running as Xcode 6.3 is still in beta. 😕

Extensions

There are some build in extensions to make your live easier.

NSOperatingSystemVersion

NSOperatingSystemVersion conforms to SemanticVersion so it can be compared with all other structs / objects that conform to the same protocol (e.g. Version).

So you can check the current system Version like this (on iOS 8+):

let systemVersion = NSProcessInfo.processInfo().operatingSystemVersion
if systemVersion < Version(major: 8)
{
    // ...
}

NSBundle

You can get the version as struct Version of a NSBundle if set in the bunlde info.plist like:

let bundle = NSBundle(forClass: self.dynamicType)
if let version = bundle.version
{
	// ...
}

UIDevice

You can get the operating system version from a UIDevice object by using operatingSystemVersion which returns a Version representation of systemVersion.

let systemVersion = UIDevice.currentDevice().operatingSystemVersion
if systemVersion < Version(major: 8)
{
    // ...
}

IntegerLiteralConvertible

Converts an Integer to a Version struct. You can use this only to represent major versions.

let systemVersion = NSProcessInfo.processInfo().operatingSystemVersion
if systemVersion < 8
{
    // ...
}

Reducing the version's minor and major value to a Float is also possible. Use this with ⚠️caution⚠️ as the Float representation could lead to accuracy loss of the minor value (that is represented as fractional digits). I would not reccommend to compare with == but < , <= , > ,>= should be useful.

let systemVersion = NSProcessInfo.processInfo().operatingSystemVersion
if systemVersion.floatValue() < 8.1
{
    // ...
}

Custom extensions

Create your own extensions or Version representations by creating struct / object that conforms to SemanticVersioning. Have a look at the extensions or the Version implementation for mor information.
