DeviceKit is a value-type replacement of UIDevice.

Features

  • Equatable
  • Device identification
  • Device family detection
  • Device group detection
  • Simulator detection
  • Battery state
  • Battery level
  • Various device metrics (e.g. screen size, screen ratio, PPI)
  • Low Power Mode detection
  • Guided Access Session detection
  • Screen brightness
  • Display Zoom detection
  • Detect available sensors (Touch ID, Face ID)
  • Detect available disk space

Requirements

  • iOS 8.0+ / tvOS 9.0+ (linking against iOS 9.3 and tvOS 9.2 required)
  • Xcode 8.0+

Installation

DeviceKit can be installed in various ways.

CocoaPods

Swift 4.0 - Swift 4.2

pod 'DeviceKit', '~> 1.3'

Swift 3

pod 'DeviceKit', '~> 1.2.3'

Swift 2.3 (Unsupported)

pod 'DeviceKit', :git => 'https://github.com/dennisweissmann/DeviceKit.git', :branch => 'swift-2.3-unsupported'

Carthage

Swift 4.0 - Swift 4.2

github "dennisweissmann/DeviceKit" ~> 1.3

Swift 3

github "dennisweissmann/DeviceKit" ~> 1.2.3

Swift 2.3 (Unsupported)

github "dennisweissmann/DeviceKit" "swift-2.3-unsupported"

Manually

To install it manually, drag the DeviceKit project into your app project in Xcode. Or add it as a git submodule by running:

$ git submodule add https://github.com/dennisweissmann/DeviceKit.git

Usage

First make sure to import the framework:

import DeviceKit

Here are some usage examples. All devices are also available as simulators:

.iPhone6 => .simulator(.iPhone6)
.iPhone6s => .simulator(.iPhone6s)

You can try these examples in Playground.

Note:

To try DeviceKit in the playground, open the DeviceKit.xcworkspace and build DeviceKit.framework for any simulator first by selecting "DeviceKit" as your current scheme.

Get the Device You're Running On

let device = Device()

print(device)     // prints, for example, "iPhone 6 Plus"

if device == .iPhone6Plus {
  // Do something
} else {
  // Do something else
}

Get the Device Family

let device = Device()
if device.isPod {
  // iPods (real or simulator)
} else if device.isPhone {
  // iPhone (real or simulator)
} else if device.isPad {
  // iPad (real or simulator)
}

Check If Running on Simulator

let device = Device()
if device.isSimulator {
  // Running on one of the simulators(iPod/iPhone/iPad)
  // Skip doing something irrelevant for Simulator
} 

Get the Simulator Device

let device = Device()
switch device {
case .simulator(.iPhone6s): break // You're running on the iPhone 6s simulator
case .simulator(.iPadAir2): break // You're running on the iPad Air 2 simulator
default: break
}

Make Sure the Device Is Contained in a Preconfigured Group

let groupOfAllowedDevices: [Device] = [.iPhone6, .iPhone6Plus, .iPhone6s, .iPhone6sPlus, .simulator(.iPhone6), .simulator(.iPhone6Plus), .simulator(.iPhone6s), .simulator(.iPhone6sPlus)]
let device = Device()
 
if device.isOneOf(groupOfAllowedDevices) {
  // Do your action
}

Get the Current Battery State

Note:

To get the current battery state we need to set UIDevice.current.isBatteryMonitoringEnabled to true. To avoid any issues with your code, we read the current setting and reset it to what it was before when we're done.

if device.batteryState == .full || device.batteryState >= .charging(75) {
  print("Your battery is happy! 😊")
}

Get the Current Battery Level

if device.batteryLevel >= 50 {
  install_iOS()
} else {
  showError()
}

Get Low Power mode status

if device.batteryState.lowPowerMode {
  print("Low Power mode is enabled! 🔋")
} else {
  print("Low Power mode is disabled! 😊")
}

Check if a Guided Access session is currently active

if device.isGuidedAccessSessionActive {
  print("Guided Access session is currently active")
} else {
  print("No Guided Access session is currently active")
}

Get Screen Brightness

if device.screenBrightness > 50 {
  print("Take care of your eyes!")
}

Get Available Disk Space

if Device.volumeAvailableCapacityForOpportunisticUsage ?? 0 > Int64(1_000_000) {
  // download that nice-to-have huge file
}

if Device.volumeAvailableCapacityForImportantUsage ?? 0 > Int64(1_000) {
  // download that file you really need
}

Source of Information

All model identifiers are taken from the following website: https://www.theiphonewiki.com/wiki/Models or extracted from the simulator app bundled with Xcode.
