// Since iOS 14, we can use PHPickerViewController to select images from the photo library
//
// The following condition checks if the iOS 14 SDK is available for XCode
// which is true for XCode 12+. It does not check on runtime, if the device is running iOS 14+.
// For that API_AVAILABLE(ios(14)) is used for methods declarations and @available(iOS 14, *) for the code.
// The condition here makes just sure that the code can compile in XCode
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 140000 // Always true on XCode12+

// Import UniformTypeIdentifiers.h for using UTType* things, available since iOS 14,
// which replaces for e.g. kUTTypeImage with UTTypeImage, which must be used in the future instead
// Currently only used for PHPickerViewController

// Import PhotosUI framework for using PHPickerViewController
// PhotosUI is already available since iOS 8, but since we need it currently
// only for the PHPickerViewController, we import it conditionally here
