This was mentioned in his tweet by Sean Lindersey, program manager of the browser Edge. So Apple users can not wait very long.
And more specifically
Sean did not name exact dates, but it was said that the version for the iPad will be tested through Microsoft TestFlight next month and soon after that it will be released. At the moment, the Edge browser has already been ported to iOS and Android, where it has gained some popularity. Especially users were pleased with the high speed of work, although the lack of Russian language and high memory consumption slightly overshadows the picture.
