NSURLConnection finished with error - code -1002 when trying to encode URL in iOS

I was trying to encode a URL. The code works fine when I encode files in my bundle. But when I tried to encode the files written to Documents and Cache, the program fails to encode.

Here is my encoder:

private class func EncodeURL(_ url:URL,encoding:UInt) ->String {
    do{
        return try NSString(contentsOf: url, encoding: encoding) as String
    }catch{}

    return ""
}

I'm using the following three:

content = EncodeURL(url, encoding: String.Encoding.utf8.rawValue)
content = EncodeURL(url, encoding: 0x80000632)
content = EncodeURL(url, encoding: 0x80000631)

And none of them work.

Here is the code I use to generate files. I'm putting them in the Documents Folder.

func writeFile(fileName:String,data:NSData)->Bool{

    guard let filePath = createFilePath(fileName: fileName) else{
        return false
    }
    return data.write(toFile:filePath,atomically:true)
}

func createFilePath(fileName:String)->String?{
    let dir = getCachePath() 
    if(!dirExists(dir: dir) && !createDir(dir: dir)){
        return nil
    }
    let filePath = dir + fileName
    if(fileExists(path: filePath)){
        do{
            try getFileManager().removeItem(atPath: filePath)
        }catch{
            return nil
        }
    }
    return filePath
}

func getCachePath()->String{
    var cacheDir = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, .userDomainMask, true).first!
    if(!cacheDir.hasSuffix("/")){
        cacheDir += "/"
    }
    cacheDir += CACHEPATH + "/" //CACHEPATH is just NSHomeDirectory()
    return cacheDir
}

writeFile(fileName: String(timeInterval)+"_"+somestring+".txt", data: data! as NSData)

Above is how I generate the files.

And how I passed URL is:

url = URL(string:getCachePath()+bookname+".txt")

passing this to

EncodeURL(url:URL,encoding:UInt)

My URL is:

/Users/houki/Library/Developer/CoreSimulator/Devices/67C921C8-18A3-4A3F-81FF-C3AF04E88049/data/Containers/Data/Application/85633861-90E6-4DB8-95B0-86C359C74C6B/Documents//Users/houki/Library/Developer/CoreSimulator/Devices/67C921C8-18A3-4A3F-81FF-C3AF04E88049/data/Containers/Data/Application/85633861-90E6-4DB8-95B0-86C359C74C6B/1511757881.83107_bigbrother.txt

Does this look weird? I'm testing it on a simulator though.

But actually this worked just fine when I tried to read files through the path. The following code is working.

let contentsofPath = try FileManager.default.contentsOfDirectory(atPath: getCachePath())

For anyone still looking for a solution on Objective-C,

If you are trying to access the bundle file, to create NSURL you'll have to use

fileURLWithPath

instead

URLWithString

. Usually, -1002 error suggests, the URI is invalid.

For Objective-C, below can be the code -

NSURL *url = [NSURL fileURLWithPath:resourceURL];

later, you can utilize this URI in your code.

This worked for me. A simple Single view app running on iphone 6s simulator gave error 1022 until I added Allow Arbitrary loads. my url was not local to Iphone, but to an external url though. Thanks info.plist snapshot

It could also be because your url is not https

Add this in your plist

<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>

or get the secure version of http url

You are not creating your URL correctly. You are passing a path to the string argument. You need to use the URL(fileURLWithPath:) initializer.

let url = URL(fileURLWithPath: path)

Only use the URL(string:) initializer if the string you pass is a valid URL beginning with a URL scheme.
