使用文件内容初始化字符串(Swift)

import Foundation

func initializeStringFromFile(filePath: String) -> String? {
    do {
        let fileManager = FileManager.default
        if fileManager.fileExists(atPath: filePath) {
            if let fileData = fileManager.contents(atPath: filePath) {
                let stringEncoding = String.Encoding.utf8
                if let fileString = String(data: fileData, encoding: stringEncoding) {
                    return fileString
                }
            }
        }
    } catch {
        // 处理可能的错误
        print("Error: \(error)")
    }
    return nil
}

// 使用示例
if let filePath = Bundle.main.path(forResource: "example", ofType: "txt") {
    if let fileString = initializeStringFromFile(filePath: filePath) {
        print("Initialized string from file: \(fileString)")
    }
}
