I am the android developer and almost newbie in the IOS world. the last year, I almost gave up to publish IOS App because of a lot of out-dated-resources and lack of references. but after I subscribed it and purchased your books also especially your blog's posts which well organized with up-to-date syntax posts help me to publish some apps. I appreciate it.

Is there a way to alter the default value from 0 to another number or to change the default bool from false to true?

Nice! It also worked to add an onAppear for the button and put the retrieve from defaults code in there. Would this cause issues?

Does this work if i have a lot of questions in my app, that need short answers?

This tutorial is very clear and very helpful! I'm trying to do a project that I know works in obj-c but I'd like to modernize it in Swift if possible. Do you know how to consume Managed App settings into UserDefaults? I'm not even sure if I'm asking that correctly. I want to send managed settings to my app via MDM and all signs point to UserDefaults to do just that. Here are some of the resources I've been banging my head against the wall with. Any help would be GREATLY appreciated!

Is it possible to trigger a block of code (for example save in UserDefaults) when the user edits the TextField, I have tried out onDisappear and onEditingChange but this doesn't save the last edit in the Textfield if the user closes the app before switching screens or doing something else. I think the option doesn't exist. For a UITextField I would use UITextFieldDelegate / textFieldDidChange
