I've written an html page with the Apple meta to link at my app in the App Store:
<meta name="apple-itunes-app" content="app-id=MY_APP_ID" app-argument="myschema:http://example.com">
The documentation
(https://developer.apple.com/library/content/documentation/AppleApplications/Reference/SafariWebContent/PromotingAppswithAppBanners/PromotingAppswithAppBanners.html)
says that with "app-argument" the app fires application:openURL:sourceApplication:annotation: method and pass as url the app-argument.
The method doesn't been called.
The documentation of the methods say to use new method application:openURL:options:, nothing change.
I read in other answer that this meta works only with the release app version (so isn't debuggable), so I put an hidden file log in the app and log at first line of method to be sure that the problem isn't my code in the method.
I tried in with ios11 and ios11.1
Any suggestion?
The documentation link you included specifically shows "app-argument" should be part of the value given to the content attribute and not an attribute itself. Notice where the quotation marks are:
<meta name="apple-itunes-app" content="app-id=myAppStoreID, affiliate-data=myAffiliateData, app-argument=myURL">
