String Shown as Unicode - Swift

Question

When I print a String array to the log most of the Strings show up like they're suppose to, but sometimes the show like this:

\U200e\U05d3\U05d5\U05e8\U05d9\U05ea \U05dc\U05d5\U05d9\U200e

What is causing this problem?

but why some of the string show like this "Hello" and some in unicode? — Omer, Jul 17 '15 at 14:42
That's how Cocoa logging works. "Hello" is ASCII. Hebrew characters are not. — matt, Jul 17 '15 at 14:42

When you log an array with NSLog, or when you log an NSArray with print, you are relying on Cocoa's logging. It's very old so it represents a non-ASCII string by showing its codepoints.

If you don't like that, log with Swift's print and make sure you are logging a Swift Array, not an NSArray.

let s = "\u{200e}\u{05d3}\u{05d5}\u{05e8}\u{05d9}\u{05ea}"
NSLog("%@",[s])       // Cocoa is logging
print([s] as NSArray) // Cocoa is logging
print([s])            // Swift is logging
