Swift：使用strftime和localtime进行NSDate格式化

Question

如何将以下Objective-C代码转换为Swift代码？

#define MAX_SIZE 11
char buffer[MAX_SIZE];
time_t time = [[NSDate date] timeIntervalSince1970];
strftime(buffer, MAX_SIZE, "%-l:%M\u2008%p", localtime(&time));
NSString *dateString = [NSString stringWithUTF8String:buffer];
NSLog(@"dateString: %@", dateString); // dateString: 11:56 PM

我正在格式化date。

    let maxSize: UInt = 11
    var buffer: CChar[] = CChar[](count: Int(maxSize), repeatedValue: 0)
    var time: time_t = Int(NSDate().timeIntervalSince1970)
    var length = strftime(&buffer, maxSize, "%-l:%M\u2008%p", localtime(&time))
    var dateString = NSString(bytes: buffer, length: Int(length), encoding: NSUTF8StringEncoding)
    NSLog("dateString: %@", dateString) // dateString: 11:56 PM
