class func println<T>(message: T, file: String = __FILE__, method: String = __FUNCTION__, line: Int = __LINE__) {
   #if DEBUG
       print("* ----------------------\n* File: \((file as NSString).lastPathComponent)\n* Line: \(line)\n* Function: \(method)\n* \(message)\n")
   #else
       // save logs
   #endif
}

与上一篇类似,我们的输出依然会额外添加文件名、方法名、行号等信息。

let abc = "def"
println("abc = \(abc)")
println("Some log")

看看输出结果:

* ----------------------
* File: ViewController.swift
* Line: 19
* Function: viewDidLoad()
* abc = def

* ----------------------
* File: ViewController.swift
* Line: 20
* Function: viewDidLoad()
* Some log
