Developers of iOS apps are now able to provide their creations to more people for testing, after the limits for
TestFlight were increased. An
announcement on Apple's developer portal revealed the previous limit of 1,000 external beta testers has doubled to 2,000, allowing developers to increase their testing pool for iPhone, iPad, iPod touch, and Apple TV apps, with app creators likely to receive more feedback ahead of their app or update's release.
The number of participants in a beta is not the only TestFlight alteration to take place. The expiration time for TestFlight beta builds has also doubled in length, upgraded from 30 days to 60. While external testing has received some changes, internal testing remains the same, with a maximum of 25 team members assigned Technical or Admin roles in iTunes Connect able to try the app out on up to ten devices each.
New external testers can be invited to a TestFlight beta via an invitation email, which prompts the installation of the free TestFlight app. Users are notified via the app whenever a new build is available, with developers also able to provide instructions for what areas of the app to focus on when giving feedback.
