OSInfo

Cross-platform Swift Package to report the operating system name and version on which the app is running

Key Aspects:

• a cross-platform API that works for iOS, iPadOS, watchOS, tvOS, macOS, Mac Catalyst, Linux and Windows
• a universal API so that you don’t need to worry about the various underlying APIs (UIDevice vs. WKInterfaceDevice vs. ProcessInfo)
• Dealing with the fact that iOS Apps on Mac and Mac Catalyst deal with two versions, the macOS version the app is running on (or targeting) and the iOS (support) version that macOS version corresponds with.
  • The package default behavior is to obtain the underlying macOS version while still having the option to get the “iOS support version” if desired.

import OSInfo

// Example for running on iPhone
print(OS.current.name) // "iOS"
print(OS.current.version) // OperatingSystemVersion(majorVersion:16, minorVersion:1,patchVersion:0)
print(OS.current.version.description) // "16.1"
print(OS.current.displayVersion) // "Version 16.1 (Build 20B72)"

// Example for running on iPad
print(OS.current.name) // "iPadOS"
print(OS.current.version.description) // "16.1"
print(OS.current.displayVersion) // "Version 16.1 (Build 20B72)"
print(OS.iOSFamily) // true

// Example for running on Apple Watch
print(OS.current.name) // "watchOS"
print(OS.current.version.description) // "9.1"
print(OS.current.displayVersion) // "Version 9.1 (Build 20S75)"

// Example for running on Mac
print(OS.current.name) // "macOS"
print(OS.current.version.description) // "13.0.1"
print(OS.current.displayVersion) // "Version 13.0.1 (Build 22A400)"
print(OS.appleFamily) // true

// Example for running as Mac Catalyst (or unmodified iOS app) on Mac
print(OS.current.name) // "macOS"
print(OS.current.version.description) // "13.0.1"
// -- alternative
print(OS(underlyingMacOS: false).name) // "iPadOS"
print(OS(underlyingMacOS: false).version.description) // "16.1"

print(OS.current.displayVersion) // "Version 13.0.1 (Build 22A400)"

// Example for running on Linux
print(OS.current.name) // Linux
print(OS.current.version) // 5.15
print(OS.current.displayVersion) // Ubuntu 22.04.1 LTS
print(OS.appleFamily) // false

Note:

• OS.current is equivalent to OS(underlyingMacOS: true)
• OS() is equivalent to OS(underlyingMacOS: false)
