UIDeviceFamily UIDeviceFamily (Number or Array - iOS) Specifies the underlying hardware type on which this app is designed to run. Important: Do not insert this key manually into your Info.plist files. Xcode inserts it automatically based on the value in the Targeted Device Family build setting. You should use that build setting to change the value of the key. The value of this key is usually an integer but it can also be an array of integers. Table 4 lists the possible integer values you can use and the corresponding devices. Table 4 Values for the UIDeviceFamily key Value Description 1 (Default) The app runs on iPhone and iPod touch devices. 2 The app runs on iPad devices. This key is supported in iOS 3.2 and later. This is written inside officuial doc. Can we update these values using command line tool without using xcode? Like I want to update this using fastlane. Suggest which key I can use and also suggest the values I need modify??
