YouTube Links

iOS 9 tries to open YouTube links within the YouTube app, but only if your app is configured correctly.

The Issue

If your document contains links they will open up in a webpage like other links. This changes when the YouTube app is installed. Then iOS tries to open the YouTube app, but fails with a "No handler found for" alert. Additionally you will see the following log message:

-canOpenURL: failed for URL: "youtube://" - error: "This app is not allowed to query for scheme youtube"

The Solution

In order for your app to be allowed to query for the youtube scheme you need to add a LSApplicationQueriesSchemes key to your Info.plist containing the scheme you want to allow:

After that you can tap on a YouTube link and an alert will appear, asking if you want to open the link in the YouTube app or not.
