LXSemVer

LXSemVer aims to provide a simple yet specification compliant implementation of Semantic Versioning 2.0.0 (SemVer) in Swift 4.x.

Features

• Parsing version string into Version instances.
• DotSeparatedValues (DSV) class to represent prerelease and/or build metadata.
• DotSeparatedValues and Version instances support next(), which provides a list of logical next DSVs and/or versions.
• DotSeparatedValues and Version instances follows SemVer's precedence rule.

Requirements

• Mac OS X 10.10+ / iOS 8.0+
• Xcode 9.0+

Installation

CocoaPods

pod "LXSemVer", "~> 3.0"

Carthage

github "trifia/LXSemVer" ~> 3.0

Usage

Parsing a Version String

import LXSemVer

if let version = Version(string: "1.0.0") {
	print(version)
}

From String Literal and Getting Next Verions

import LXSemVer

let version: Version = "1.0.1-alpha.1"
print(version.next())

Compatibility

LXSemVer 3.0 uses Swift 4.

For projects using Swift 3, please use LXSemVer 2.0.

For projects using Swift 2.2 or older, please use LXSemVer 1.2.

Concept

Version Graph

LXSemVer unique point is its concept of version graph. SemVer precedence rule (SemVer Specification 11) allow for logical digraph of versioning.

At any specific version, there are multiple logical paths leading to the next versions and these versions have logical ordering between them as well.

LXSemVer extends on SemVer by recognizing alpha, beta and rc as the first prerelease identifiers.

Together, they make LXSemVer an excellent choice for versioning management.
