stringByAppendingPathComponent is unavailable

Solution 1:

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URLByAppendingPathComponent() has been replaced by appendingPathComponent() so instead do: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

Solution 2:

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)
    }
}

Solution 3:

Simply wrap your string as NSString.

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

Solution 4:

for Swift 3:

let writePath = URL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(directoryname).path

or better create this extension:

extension String {
    func appendingPathComponent(_ string: String) -> String {
        return URL(fileURLWithPath: self).appendingPathComponent(string).path
    }
}

usage:

 let writePath = NSTemporaryDirectory().appendingPathComponent(directoryname)
