In the upcoming MBS Xojo Plugins in version 22.5, we add new classes to show a ProgressView. Check out what you can do with ProgressHUDMBS class:

As you see, we support determinate and indeterminate (value set to negative) with two labels below. Feel free to test in your Xojo iOS app with the current 22.5pr4 pre-release. The look can be switched between round or bar for showing progress, indeterminate circle animation and colors can be adjusted.
