apps stuck on loading new iphone

Hi Corndogy,

Thank you for using the Apple Support Communities. We understand that some of the apps on your new iPhone are stuck on loading and we are happy to help! To resolve this problem here are some “Things you can check

• Make sure that you correctly restored your iOS device from iCloud Backup. When you sign in to iCloud, it's not the same as when you restore from iCloud Backup. Learn how to restore from iCloud Backup. 
• Make sure that iCloud Backup includes the kind of information that you’re missing. If you restore an iPad from an iPhone backup or vice versa, some data won’t restore.
• If an app asks for your Apple ID password during the restore process, make sure that you enter it. Some apps and services, like the App Store, need your password before they can restore purchased content. If you purchased content on multiple Apple IDs, enter the password for each Apple ID when prompted.
• If the restore process takes a long time to finish, or if you receive an error message, learn what to do.
• You can also check to see if you have any backups on your computer that may contain the data that’s missing.
• Sometimes the restore process may look complete, but your device is still downloading information in the background. To check this, tap Settings > [your name] > iCloud > iCloud Backup. If your device is still being restored, you see “This [device] is currently being restored and will automatically back up when it is done.”

For additional information check out the Apple Support articles About missing information after you restore your iPhone, iPad, or iPod touch with iCloud Backup and If you can’t download or update apps on your iPhone or iPad. 

We hope this helps.

Take care.
