我确切地说几天相同的问题，

I had the exactly same issue for couple of days,

试试这个解决了我的问题，确保有一个值

Try this its solved my problem, make sure that there is a value

（应用程序名称为字符串）在info.plist>Bundle display name中。

(Application name as string) in your info.plist > "Bundle display name".

在我的情况下它是空的，因为它不起作用。

In my case it was empty and because of that it didn't work.

让我知道它是否对你有帮助。

let me know if it helped you.
