WARN: WARNING ITMS-90737: "Invalid Document Configuration. Document Based Apps should support either the Document Browser (UISupportsDocumentBrowser = YES) or implement Open In Place (LSSupportsOpeningDocumentsInPlace = YES/NO). Visit https://developer.apple.com/document-based-apps/ for more information."
如果你的app中有用到UIDocumentInteractionController来打开文件，需要在info.plist中设置UISupportsDocumentBrowser为YES
UISupportsDocumentBrowser官方解释
UISupportsDocumentBrowser (Boolean - iOS) Specifies that the app is a document-based app and uses the UIDocumentBrowserViewController class.
If this key is set to YES, the user can set the document browser’s default save location in Settings. Additionally, the local file provider grants access to all the documents in the app’s Documents directory. These documents appear in the Files app, and in a Document Browser. Users can open and edit these document in place.
This key is supported in iOS 11 and later.
