Any help is appreciated

\"cannot use optional chaining on non-optional valu

Answer 1

You get that error as your context variable is not optional so the ? is useless.

Also swift 2 introduced the do-catch construct to allow advanced error handling as you would do in other languages with try-catch, so functions with an error parameter such as save() of NSManagedObjectContext changed and have lost the error parameter and report errors as exceptions; so you should do

do {
    try context.save()
} catch let error {
    // Handle error stored in *error* here
}

If you don't want to handle the error you can do

do {
    try context.save()
} catch {}
