stringByAppendingPathComponent is unavailable

It looks like the method stringByAppendingPathComponent is removed in Swift 2.0, so what the error message suggests is to use:

let writePath = NSURL(fileURLWithPath: NSTemporaryDirectory()).URLByAppendingPathComponent("instagram.igo")

Update:

URLByAppendingPathComponent() has been replaced by appendingPathComponent() so instead do:

let writePath = NSURL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent("instagram.igo")

It is working for NSString so you can use it like this:

extension String {    func stringByAppendingPathComponent(path: String) -> String {        let nsSt = self as NSString        return nsSt.stringByAppendingPathComponent(path)    }}

Now you can use this extension which will convert your String to NSString first and then perform operation.

And your code will be:

let writePath = NSTemporaryDirectory().stringByAppendingPathComponent("instagram.igo")

Here is some another methods for use:

extension String {      var lastPathComponent: String {          return (self as NSString).lastPathComponent      }      var pathExtension: String {          return (self as NSString).pathExtension      }      var stringByDeletingLastPathComponent: String {          return (self as NSString).stringByDeletingLastPathComponent      }      var stringByDeletingPathExtension: String {          return (self as NSString).stringByDeletingPathExtension      }      var pathComponents: [String] {          return (self as NSString).pathComponents      }      func stringByAppendingPathComponent(path: String) -> String {          let nsSt = self as NSString          return nsSt.stringByAppendingPathComponent(path)      }      func stringByAppendingPathExtension(ext: String) -> String? {          let nsSt = self as NSString          return nsSt.stringByAppendingPathExtension(ext)      }  }

Reference from HERE.

For swift 3.0:

extension String {    func stringByAppendingPathComponent1(path: String) -> String {        let nsSt = self as NSString        return nsSt.appendingPathComponent(path)    }}let writePath = NSTemporaryDirectory().stringByAppendingPathComponent(path: "instagram.igo")extension String {    var lastPathComponent: String {        return (self as NSString).lastPathComponent    }    var pathExtension: String {        return (self as NSString).pathExtension    }    var stringByDeletingLastPathComponent: String {        return (self as NSString).deletingLastPathComponent    }    var stringByDeletingPathExtension: String {        return (self as NSString).deletingPathExtension    }    var pathComponents: [String] {        return (self as NSString).pathComponents    }    func stringByAppendingPathComponent(path: String) -> String {        let nsSt = self as NSString        return nsSt.appendingPathComponent(path)    }    func stringByAppendingPathExtension(ext: String) -> String? {        let nsSt = self as NSString        return nsSt.appendingPathExtension(ext)    }}

Simply wrap your string as NSString.

let writePath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent("instagram.igo")
