Swift開發調試日志框架：XCGLogger

XCGLogger是一個debug日志框架，用于Swift項目中。允許您記錄詳細信息到控制臺（還有一個可選的文件）。就像你用NSLog或println，但還有其他額處信息，如日期，函數名，文件名和行號。

import XCGLogger

let log = XCGLogger.defaultInstance()

log.verbose("A verbose message, usually useful when working on a specific problem")
log.debug("A debug message")
log.info("An info message, probably useful to power users looking in console.app")
log.error("An error occurred, but it's recoverable, just info about what happened")
log.severe("A severe error occurred, we are likely about to crash now")
