What certificate does Xcode cloud use when distribute apps to App Store? Since cloud managed certs can't be downloaded, how to get its public key for the f..king recordation in China?

只能在string catalog里面添加语言，不能删除语言？？这是什么设计？ 在Project里面删除语言，并不能删除Localizable中的语言。但是如果这个语言没有任何国际化，是可以的。 也就是说，删不了曾经做过国际化的语言。 我应用还没发布，还在开发呢，为什么不让我删除语言？？？？？？？？？？？？？？？？？？？？？？？？？？、

I have a Localizable file under Assets. I can add a language by click the + button. But I can't remove it then??!! Remove a localization in project -> info does not work. If the localization contains some translation, it still remains in the catalog (works if not translated at all). As a result, your app will not show the default localization at all.

Is there a way to make other apps' window pinned to float mode? Is Accessibility API able to do this?
