This is not an iCloud photos not uploading problem and you may just wait. If you find the iCloud Photo Library stuck uploading from Mac on iPhone XS/SR/X/8/7/6S or iPad, try the fixes below.
1. Check if you have enough space on iCloud
If you have updated to iOS 11/12, the two new formats HEVC and HEIF will cut half the storage of your photos. If you're not an early adopter, you should know that the 12-megapixel photos, live photos and 4K recordings will still take large space - generally the size of a Live photo (HDR) taken from iPhone is in the range of 3-4MB, 1MB larger than still photo.
Specifically, up to 2000 photos will consume iCloud 5GB storage and lead to iCloud storage full error. If your iPhone photos won't upload to iCloud, check Settings > iCloud > Storage.

After I did a good deal of searches on various forums and found a user with photos not uploading to iCloud Photo Library citing that the Apple Support told him to sign out of iCloud and then sign in. And the fix works for many users. Another similar fix is to toggle iCloud Photos on and off, that also helps!

You can either forget this network and rejoin: Settings > Wi-Fi > Choose Home Network> Forget This Network > turn off Wi-Fi from your iPhone > turn it on and rejoin the Wifi network; or reboot your home Wi-Fi. Then try again to see if your iCloud photo uploading is back to normal.

For some users who is uploading their photos to iCloud for freeing up space on their device can hardly have any extra room. But many users don't know that if your device is too crowded, the problem of 'iCloud backup couldn't be completed' also happens.

A user also mentioned that a full deletion of the photos from the device will help fix iCloud photos not syncing to Mac. Specifically, you need to transfer all photos from iPhone to Mac, clear out your camera roll on iPhone and then re-import the pictures you want to upload to iCloud. To do this, you can use Image Capture, iTunes or a third-party iPhone file manager.

It's easy.If you like, you can download tinker tool and add a Quit option to the finder in both your user and root accounts, it makes clean switching easier. Using Mac OS 10.3.8 I can just drop into the shell and do:sudo /System/Library/CoreServices/Finder.app/Contents/MacOS/Finderand away I go!I can do my switching through the command-option-esc force-quit window, and force-quit or relaunch finders as I like as I go.

'My 5000 + photos were uploaded in a couple of days.', 'For me it took 4-5 days to upload about 1700 photos.', 'It took me about 5 days to complete'.. If you're tired of hours and days of babysitting during which you have to make sure the battery is full, the photos app open and the Wi-Fi is connected, and if you simply want to free up more space and keep your photos safe, you can backup them to your computer with a third-party app. The app for me is called MacX MediaTrans.
