How can I get mime type from NSData object. I want to detect zip file. Please help ASAP.

@darko55555

Hey, I've made an optimization for Swift where it uses optional in a bit cleaner way. You can check it out on my fork, or just replace it with:

internal func MimeType(ext: String?) -> String {
    if let ext = ext?.lowercased(), let mimeType = mimeTypes[ext] {
        return mimeType
    }else{
        return DEFAULT_MIME_TYPE
    }
}
