在Swift中启动终端编辑器，如vi或nano

import Foundation

let process = Process()

process.launchPath = "/usr/bin/vi"

process.arguments = ["path/to/file"]

let pipe = Pipe()
process.standardOutput = pipe

process.launch()
process.waitUntilExit()

let data = pipe.fileHandleForReading.readDataToEndOfFile()
if let output = String(data: data, encoding: .utf8) {
    print(output)
}
