Swift 版本号判断比较更新APP

    func compareVersions(newVersion: String) {
        let currentVersion = Bundle.main.infoDictionary!["CFBundleShortVersionString"] as! String
        let currentVersions = currentVersion.split(separator: ".").compactMap { Int($0) }
        let newVersions = newVersion.split(separator: ".").compactMap { Int($0) }

        guard currentVersions.count == 3, newVersions.count == 3 else {
            print("Invalid version format")
            return
        }

        if newVersions[0] > currentVersions[0] ||
           (newVersions[0] == currentVersions[0] && newVersions[1] > currentVersions[1]) ||
           (newVersions[0] == currentVersions[0] && newVersions[1] == currentVersions[1] && newVersions[2] > currentVersions[2]) {
            print("需要更新到新版本 \(newVersion)")
            // 执行更新操作
        } else if newVersion == currentVersion {
            print("版本相同，无需更新")
        } else {
            print("当前版本大于新版本，无需更新")
        }
