WWDC week starts Monday and the pace will be fast — Apple typically seeds the first betas within hours of the keynote. Developers planning to test against the next major iOS release should have a spare device ready and watch for the beta profile drop through the Developer app. The announcement lands while 26.6 betas are already circulating, which is a slightly compressed overlap this year. Expect session content on the new APIs to go live in the developer portal shortly after the keynote ends.
