Hi I am currently creating an app specifically for my family trip. I was wondering how I can get my finished xcode app onto their phones. I do not want to use testflight because it will expire in a set amount of days. Is there anyway to get my finished app onto their phones without expiring?
Distributing apps for private use without them expiring
Apple has detailed instructions on how to distribute internal apps available here. You need to make a special provisioning profile discussed in the link above.
