Mac OS Swift:将崩溃日志写入文本文件

import Foundation

func uncaughtExceptionHandler(exception: NSException) {
    let dateFormatter = DateFormatter()
    dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
    let dateString = dateFormatter.string(from: Date())
    
    let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]
    let filePath = documentsPath.appending("/crashlog.txt")
    
    let exceptionInfo = """
    Exception name: \(exception.name.rawValue)
    Exception reason: \(exception.reason ?? "")
    Exception call stack: \(exception.callStackSymbols.joined(separator: "\n"))
    Date: \(dateString)
    """
    
    do {
        try exceptionInfo.write(toFile: filePath, atomically: true, encoding: .utf8)
        print("Crash log written to: \(filePath)")
    } catch {
        print("Failed to write crash log: \(error)")
    }
}

// 设置未捕获异常处理器
NSSetUncaughtExceptionHandler { exception in
    uncaughtExceptionHandler(exception: exception)
}

// 人为制造一个崩溃
let array = [1, 2, 3]
let element = array[4]
