Device.swiftpm

Device is a value-type replacement for device information on all supported platforms (very similar to DeviceKit but designed to be easier to maintain). Device definitions include clear initializers so anyone can add new devices and contribute to the project even on an iPad using Swift Playgrounds rather than requiring Xcode. No need to memorize mapping schema or use additional build tools.

The primary goals are to be easily maintainable by multiple individuals, employ a consistent API that can be used across all platforms, and to be maintainable using Swift Playgrounds on iPad and macOS. APIs are typically present even on platforms that don't support all features so that availability checks do not have to be performed in external code, and where irrelevant, code can simply return optionals.

This is actively maintained so if there is a feature request or change, we will strive to address within a week.

Requirements

• iOS 11+ (15.2+ minimum required for Swift Playgrounds support)
• macOS 10.5+ (UI only supported on macOS 12.0+)
• macCatalyst 13.0+ (first version available)
• tvOS 11.0+ (UI only supported on tvOS 15.0+, 17+ required for most SwiftUI features)
• watchOS 4.0+ (UI only supported on watchOS 8.0+)
• visionOS 1.0+
• Theoretically should work with Linux, Windows, and Vapor, but haven't tested. If you would like to help, please let us know.

Known Issues

Built for macOS "Designed for iPad" returns an iPad profile instead of actual hardware profile. Custom Symbols likely won't work in macOS < 13 or watchOS < 7. LowPowerMode checks unavailable in macOS < 12. See CHANGELOG.md for more known issues and roadmap

Installation

Install by adding this as a package dependency to your code. This can be done in Xcode or Swift Playgrounds!

Swift Package Manager

Swift 5+

You can try these examples in a Swift Playground by adding package: https://github.com/kudit/Device

If the repository is private, use the following link to import: https://<your-PAT-string>@github.com/kudit/Device.git

Or you can manually enter the following in the Package.swift file:

dependencies: [
    .package(url: "https://github.com/kudit/Device.git", from: "2.0.0"),
]

Usage

First make sure to import the framework:

import Device

Here are some usage examples.

Get the version of Device that is imported.

let version = Device.version

Get the device You're Running On

let device = await Device.current // await required if not on the main thread (@MainActor isolated)

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

if device.has(.force3dTouch) {
    // do something that needs force-touch.
} else {
    // fallback for devices that do not support this.
}

if device.is(.plus) || device.is(.max) {
    // do something only available for "Plus" model devices.
}

if device.has(.battery) && device.has(.lidar) && device.has(.headphoneJack) {
    // do something only if there is a battery, lidar, and a headphoneJack
}

Get the full list of flags that can be queried for under the enum Capability in Hardware.swift.

Get the device idiom

let device = Device.current
if device.idiom == .pad {
  // iPad
} else if device.idiom == .phone {
  // iPhone
} else if device.idiom == .vision {
  // Apple Vision device
}

Check if running in a Simulator

if Device.isSimulator {
  // Running on one of the simulators
  // Skip doing something irrelevant for Simulator
} 

Check if running in a Preview

if Device.isPreview {
  // Running in an XCode #Preview
} 

Check if running in a Playground

if Device.isPlayground {
  // Running in an XCode #Preview
} 

Check if running on a physical device

if Device.isRealDevice {
  // Running on physical hardware and not a simulator
} 

Get the Current Battery State

Note:

When getting the current battery state, battery monitoring enabled will be temporarily set to true and then restored to whatever it was beforehand, so no need to manage monitoring separately. If you need to be notified when the battery state or level changes, you can add a monitor that will call your code whenever the level changes. However, typically this can just be dropped in as the DeviceBattery is an ObservableObject.

if let battery = Device.current.battery {
    // do things that need the battery
    if battery.currentState == .full || (battery.currentState == .charging && battery.currentLevel >= 75) {
        print("Your battery is happy! 😊")
    }
    
    // get the current battery level
    if battery.currentLevel >= 50 {
        install_iOS()
    } else {
        showLowBatteryWarning()
    }

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

    // add monitor to do something whenever battery level changes (like updating UI)
    battery.addMonitor {
        localBatteryLevel = battery.currentLevel
        localBatteryState = battery.currentState
    }
} else {
    // handle behaviour on devices without a battery
}

Get the Current Battery Level

if let level = Device.current.battery?.currentLevel, level >= 50 {
  install_iOS()
} else {
  showError()
}

Check if a Guided Access session is currently active

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

Get Screen Brightness

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

Get Available Disk Space

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

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

Disabling the Idle Timer

Device.current.isIdleTimerDisabled = true // must be run on the main actor AFTER most of the UI is loaded (so do on a view onAppear and NOT during the app init)

// Disable automatically when plugged in.  Only call this once (This would be appropriate to call during init).
Device.current.disableIdleTimerWhenPluggedIn()

Displaying a BatteryView

// BatteryView() will default to a view with a live updating battery indicator.
BatteryView()
// you can have a larger one by changing the font size
BatteryView(fontSize: 80)

All these tests can be demonstrated using previews or by running the app executable that is bundled in the Development folder of the module.
