iOS Question Can I build and install Apps to my iPad only without store provision profile ?

If you have B4I Hosted Builder - You can compile the release version with adhoc profile, and it will install and run on only your device.

Tools -> Build Server -> Build Release App

But I think you still need developer account from apple.

Do you have an Apple developer account?

I have an Apple developer account, but don't register in Apple Developer Program.

You can run your app on the simulator without a developer account.

Running your app on a real device without a developer account is limited. The app will only work for a few days and it must be done from Xcode.
You can take the generated ObjC code and compile it from Xcode, however it will be a waste of time and you will need a developer account at some point anyway.

Thank you for a kindness reply, Erel.
I understood, my Apps work with Swift code on Xcode, but don't work with B4i.
I will register in Apple Developer Program.
