I am finishing my first IOS app, and would like to add some instructions, hints and help for users. Would like to show hint when users hover over a button, provide instructions for first time users, and help for users who appear stuck. Would appreciate a link to a comprehensive tutorial for doing this. Thanks.

When loading an app into TestFlight, there is a required input for a Beta Testing License Agreement. Are we supposed to provide our own agreements, or can we provide the link to Apple's "TestFlight Terms of Service" which covers Apple, the App Provider, and the tester? Thanks https://www.apple.com/legal/internet-services/itunes/testflight/sren/terms.html

Started having problems with Xcode 13 after installing Xcode 14 Beta 2 days ago. Xcode would quit every time I click on "main (storyboard)". Also, simulator was missing. So I deleted both Xcode and the Beta, emptied the trash can and reinstalled Xcode. Simulator was still missing. Checked the forum for possible solutions and deleted the 'developer' folder under library, and then reinstalled Xcode 13. This time it asked if I wanted to install additional components. I clicked install and Xcode quit. Now each time I try to open Xcode, it asks if I want to install additional components, but doesn't wait for me to click 'install'. It just quits! Would greatly appreciate any insights into resolving this issue. Thanks!
