From Apple’s developer blog:

Now it’s easier to discover and share information presented in WWDC videos with our recent search update. You can search a keyword and find all the instances of it mentioned in the videos. Go straight to the time the keyword was mentioned in the video or easily share a link to it.

Not only does Apple now allow you to search the WWDC session transcripts – which ASCIIwwdc has been doing for a while – you can tap on a result (like this) and be taken to the relevant point in the video from your web browser. There are also filters to select returns from specific WWDCs and you can filter by platform, too.

Extremely useful, and I wish I had this when I was writing my iOS 9 review this summer.
