我的自定义键盘应用程序扩展在我的真实设备上表现不同，但在我的 iOS 模拟器上表现良好。
我在真实设备上收到以下错误

我正在使用标准 Alamofire 代码：
Alamofire.request("https://httpbin.org/get").response { response in
print("Request: \(response.request)")
print("Response: \(response.response)")
print("Error: \(response.error)")
if let data = response.data, let utf8Text = String(data: data, …我很久以来就遇到了错误,接下来,我正在学习,我想我不明白这个错误.
droid.cpp: In function ‘std::ostream& operator<<(std::ostream&, const Droid&)’:
droid.cpp:94:30: error: passing ‘const Droid’ as ‘this’ argument of ‘std::string
Droid::getId()’ discards qualifiers
[-fpermissive]
第94行:
std::ostream& operator<<(std::ostream &os, Droid const & a)
os << "Droid '" << a.getId() << "', " << *a.getStatus() << ", " << a.getEnergy() << std::endl;
和听众:
std::string getId();
我对"operator <<",a.getId,a.getStatus,a.getEnergy中的3个调用有相同的错误.
有人可以向我解释一下编译器在说什么吗？
