I tried several method to get file size, but always get zero.
let path = NSBundle.mainBundle().pathForResource("movie", ofType: "mov")
let attr = NSFileManager.defaultManager().attributesOfFileSystemForPath(path!, error: nil)
if let attr = attr {
let size: AnyObject? = attr[NSFileSize]
println("File size = \(size)")
}
I get in log: File size = nil
Use attributesOfItemAtPath
instead of attributesOfFileSystemForPath
+ call .fileSize() on your attr.
var filePath: NSString = "your path here"
var fileSize : UInt64
var attr:NSDictionary? = NSFileManager.defaultManager().attributesOfItemAtPath(filePath, error: nil)
if let _attr = attr {
fileSize = _attr.fileSize();
}
In Swift 2.0, we use do try catch pattern, like this:
let filePath = "your path here"
var fileSize : UInt64 = 0
do {
let attr : NSDictionary? = try NSFileManager.defaultManager().attributesOfItemAtPath(filePath)
if let _attr = attr {
fileSize = _attr.fileSize();
}
} catch {
print("Error: \(error)")
}
In Swift 3.x/4.0:
let filePath = "your path here"
var fileSize : UInt64
do {
//return [FileAttributeKey : Any]
let attr = try FileManager.default.attributesOfItem(atPath: filePath)
fileSize = attr[FileAttributeKey.size] as! UInt64
//if you convert to NSDictionary, you can get file size old way as well.
let dict = attr as NSDictionary
fileSize = dict.fileSize()
} catch {
print("Error: \(error)")
}
Swift4: URL extension to easily access file attributes
Extension:
extension URL {
var attributes: [FileAttributeKey : Any]? {
do {
return try FileManager.default.attributesOfItem(atPath: path)
} catch let error as NSError {
print("FileAttribute error: \(error)")
}
return nil
}
var fileSize: UInt64 {
return attributes?[.size] as? UInt64 ?? UInt64(0)
}
var fileSizeString: String {
return ByteCountFormatter.string(fromByteCount: Int64(fileSize), countStyle: .file)
}
var creationDate: Date? {
return attributes?[.creationDate] as? Date
}
}
Usage:
let fileUrl: URL
print("file size = \(fileUrl.fileSize), \(fileUrl.fileSizeString)")
