Swift Playgrounds app

Hello, I recently created an application on Swift Playgrounds 4 and I would like me and my friends only could use it. To be able to install it, I exported it as .ipa file with a program I found on Github (here is the link: https://gist.github.com/rikestut/5b3ede1cfeaba47cea9e6c1c8c114e4e) Then I went to https://installonair.com to create a link by important my .IPA file and when I press the link I'm asked if I want to install the application, I confirm, and I find it in my app Library. But when I try to open it there is an alert that appears: "This app can not be installed because its integrity could not be checked". Would there be a way so that we can use my application?

Every distribution method which Apple does not guarantee would cause any sort of troubles and you should not rely on them. If you are a member of paid Developer Program, you can add your friends as external testers on TestFlight.
