How to tell which device I'm on in Xcode UI Testing?

Question

While an Xcode UI Test is running, I want to know which device/environment is being used (e.g. iPad Air 2, iOS 9.0, Simulator).

How can I get this information?

Answer 1

Using Swift 3 (change .pad to .phone as necessary):

if UIDevice.current.userInterfaceIdiom == .pad {
    // Ipad specific checks
}

Using older versions of Swift:

UIDevice.currentDevice().userInterfaceIdiom

Answer 2

Unfortunately there is no direct way of querying the current device. However you can work around by querying the size classes of the device:

private func isIpad(app: XCUIApplication) -> Bool {
    return app.windows.elementBoundByIndex(0).horizontalSizeClass == .Regular && app.windows.elementBoundByIndex(0).verticalSizeClass == .Regular
}

As you can see in the Apple Description of size classes, only iPad devices (currently) have both vertical and horizontal size class "Regular".

Answer 3

You can check using the windows element frame XCUIApplication().windows.element(boundBy: 0).frame and check the device type.

You can also set an extension for XCUIDevice with a currentDevice property:

/// Device types
public enum Devices: CGFloat {

    /// iPhone
    case iPhone4 = 480
    case iPhone5 = 568
    case iPhone7 = 667
    case iPhone7Plus = 736

    /// iPad - Portraite
    case iPad = 1024
    case iPadPro = 1366

    /// iPad - Landscape
    case iPad_Landscape = 768
    case iPadPro_Landscape = 0
}

/// Check current device
extension XCUIDevice {
    public static var currentDevice:Devices {
        get {
            let orientation = XCUIDevice.shared().orientation

            let frame = XCUIApplication().windows.element(boundBy: 0).frame

            switch orientation {
            case .landscapeLeft, .landscapeRight:
                return frame.width == 1024 ? .iPadPro_Landscape : Devices(rawValue: frame.width)!
            default:
                return Devices(rawValue: frame.height)!
            }
        }
    }
}

Usage

let currentDevice = XCUIDevice.currentDevice

Maybe someone would be come in handy the same for XCTest on Objective C:

// Check if the device is iPhone
if ( ([[app windows] elementBoundByIndex:0].horizontalSizeClass != XCUIUserInterfaceSizeClassRegular) || ([[app windows] elementBoundByIndex:0].verticalSizeClass != XCUIUserInterfaceSizeClassRegular) ) {
    // do something for iPhone
}
else {
    // do something for iPad
}
