How to use Spotlight searches in Swift (basic example)

QueryExample.swift

let query = MDQueryCreate(kCFAllocatorDefault, "kMDItemContentType = com.apple.application-bundle" as CFString, nil, nil)
MDQueryExecute(query, CFOptionFlags(kMDQuerySynchronous.rawValue))

let count = MDQueryGetResultCount(query);
for i in 0 ..< count {
	let rawPtr = MDQueryGetResultAtIndex(query, i)
	let item = Unmanaged<MDItem>.fromOpaque(rawPtr!).takeUnretainedValue()
	if let path = MDItemCopyAttribute(item, kMDItemPath) as? String {
		print(path)
	}
}

// let query = MDQueryCreate(kCFAllocatorDefault, "kMDItemFSLabel = 6" as CFString, nil, nil)
// let query = MDQueryCreate(kCFAllocatorDefault, "kMDItemContentType = com.apple.application-bundle" as CFString, nil, nil)
// let query = MDQueryCreate(kCFAllocatorDefault, "kMDItemUserTags == 'cat' && kMDItemUserTags == 'dog'" as CFString, nil, nil)
