Call can throw, but errors cannot be thrown out of a property initializer

Question

After updated to Swift 2.0, when NSFielManager is called, it has caused the following error. Could you tell me what is the problem?

let cachesDirectoryURL = NSFileManager().URLForDirectory(.CachesDirectory, inDomain: .UserDomainMask, appropriateForURL: nil, create: true)

Error:

"Call can throw, but errors cannot be thrown out of a property initializer"

Answer 1

Which means we have to catch the error that might be thrown, should problem occurs:

do
{
    let cachesDirectoryURL = try NSFileManager().URLForDirectory(.CachesDirectory, inDomain: .UserDomainMask, appropriateForURL: nil, create: true)
}
catch let error as NSError
{
    print(error.localizedDescription)
}
