[Swift] Convert Bytes to Kilobytes to Megabytes to Gigabytes

Units.swift

public struct Units {
  
  public let bytes: Int64
  
  public var kilobytes: Double {
    return Double(bytes) / 1_024
  }
  
  public var megabytes: Double {
    return kilobytes / 1_024
  }
  
  public var gigabytes: Double {
    return megabytes / 1_024
  }
  
  public init(bytes: Int64) {
    self.bytes = bytes
  }
  
  public func getReadableUnit() -> String {
    
    switch bytes {
    case 0..<1_024:
      return "\(bytes) bytes"
    case 1_024..<(1_024 * 1_024):
      return "\(String(format: "%.2f", kilobytes)) kb"
    case 1_024..<(1_024 * 1_024 * 1_024):
      return "\(String(format: "%.2f", megabytes)) mb"
    case (1_024 * 1_024 * 1_024)...Int64.max:
      return "\(String(format: "%.2f", gigabytes)) gb"
    default:
      return "\(bytes) bytes"
    }
  }
}

print(Units(bytes: 546546546).getReadableUnit())

Thats a very good script. Thank you.

Thanks mate!

Nice! But have you checked out ByteCountFormatter?

License?

Awesome! thanks!

Thanks

let formatted = ByteCountFormatter.string(fromByteCount: (1024 * 1024 * 8), countStyle: .file)

prints 8.4 MB
