Same issue here The error message is [UIPickerView setFrame:]: invalid size {320, 216} pinned to {320, 216} Environment: Version 14.2 (14C18) iPhone 13 Pro Max iOS 16.2

Just use @EnvironmentObject instead of @ObservableObject That should fix it.

Copy usdpython from /Applications to ~/Developer as follows - $ cp -R /Applications/usdpython ~/Developer/ Then add the following to your .bash_profile export PATH=$PATH:$HOME/Developer/usdpython/USD export PATH=$PATH:$HOME/Developer/usdpython/USD/lib/ export PATH=$PATH:$HOME/Developer/usdpython/usdzconvert
