Hi, kzei,
Thank you for visiting the Apple Support Communities.
You can delete apps from your iPhone following the below guidance, which is taken from the Apple Support article on deleting apps, Delete apps on your iPhone, iPad, and iPod touch - Apple Support:
How to delete an app
1. Touch and hold the app.
2. Tap Remove App .
3. Tap Delete App, then tap Delete to confirm.
Keep in mind that some built-in Apple apps can't be deleted from your device, so you might not see the option to delete an app. Here’s a list of built-in Apple apps you can delete from your device. If you can't delete an app that's not made by Apple, disable parental controls, then try deleting the app again.
If you touch and hold an app from the Home Screen and the apps start to jiggle:
1. Tap the Remove icon in the upper-left corner of the app.
2. Tap Delete App, then tap Delete to confirm.
3. Tap Done.
We would also encourage you to update the iOS software to iOS 16.2 if you have not already. Updating not only installs new features and other enhancements, but also resolutions to previously found issues within the iOS functionality. If the inability to delete is one such issue, updating should resolve it: Update your iPhone or iPad - Apple Support
If you're still not able to delete apps in iOS 16.2 after verifying they are not a built-in app that cannot be deleted and that parental controls are not enabled, don't hesitate to respond back.
Best!
