After updating to iOS 18, many iPhone users find that apps refuse to update — the App Store shows a spinning circle that never finishes, or the “Update” button simply does nothing. This is a known iOS 18 issue with several reliable fixes.
Why Apps Won’t Update on iPhone After iOS 18
- App Store cache conflict with the new iOS 18 file system
- Apple ID authentication token expired after the update
- Insufficient storage space (iOS 18 needs extra space during updates)
- App Store sync issue with iCloud account
- Background App Refresh disabled for the App Store
Fix 1: Force Restart Your iPhone (30 Seconds)
A force restart clears the iOS 18 memory without affecting any data:
- iPhone 8 and later: Press Volume Up → Volume Down → hold Side button until Apple logo appears
- iPhone 7: Hold Volume Down + Side button simultaneously for 10 seconds
After the restart, open the App Store and try updating again.
Fix 2: Sign Out of Apple ID, Then Sign Back In
iOS 18 sometimes invalidates the App Store authentication token during the update process:
- Open Settings → [Your Name]
- Scroll down and tap Sign Out
- Choose to keep a copy of your data when prompted
- Wait 30 seconds
- Go back to Settings and tap Sign in to your iPhone
- Enter your Apple ID and password
- Open App Store and try updating
Fix 3: Clear App Store Cache
This is a hidden trick most users don’t know about:
- Open the App Store
- Tap any of the bottom tab icons (Today, Games, Apps, etc.) 10 times quickly
- The screen will briefly flicker — this clears the App Store cache
- Go to your profile → Updates and try again
Fix 4: Free Up iPhone Storage
iOS 18 requires temporary double the space of the app being updated. If your storage is nearly full, updates will silently fail:
- Go to Settings → General → iPhone Storage
- Check available space at the top
- Delete unused apps or use the “Offload Unused Apps” recommendation
- You need at least 1–2 GB free for updates to proceed
Fix 5: Check Your Internet Connection
iOS 18 enforces stricter SSL certificate checks when downloading updates. Public Wi-Fi networks that require login pages (hotels, airports) can block App Store downloads entirely. Use your home Wi-Fi or cellular data instead.
Fix 6: Delete the Stuck Update and Redownload
If one specific app is stuck updating:
- Find the app on your home screen (it will have a progress bar)
- Long-press the app icon
- Tap Cancel Download
- Open App Store → Search for the app → tap Update again
Fix 7: Reset Network Settings
This fixes SSL and certificate issues that block App Store communication in iOS 18:
- Go to Settings → General → Transfer or Reset iPhone
- Tap Reset → Reset Network Settings
- Enter your passcode and confirm
- Reconnect to Wi-Fi and try updating again
Note: This will forget saved Wi-Fi passwords. Have your passwords ready before doing this.
Fix 8: Update Through iTunes or Finder on Mac/PC
If the App Store is completely broken on your iPhone, you can sync and update apps through your computer:
- Connect iPhone to Mac (Finder) or PC (iTunes)
- Trust the computer if prompted
- In Finder or iTunes, click your device
- Click Check for Update

Frequently Asked Questions
Why does the App Store spin forever and never download on iOS 18?
The most common cause is an expired Apple ID token or a full storage issue. Sign out and back into your Apple ID first — this resolves the spinning issue in over 60% of cases.
Will I lose app data if I delete and reinstall an app?
If the app stores data in iCloud (most modern apps do), you won’t lose anything. Apps like WhatsApp, Instagram, and banking apps store your data on their servers. However, some games store progress locally — check if the game has iCloud sync before deleting.
How much free storage does iOS 18 need for app updates?
iOS 18 typically needs about twice the size of the app being updated as temporary working space. For large apps (1 GB+), you may need 2+ GB free. Always keep at least 2 GB free on your iPhone for smooth operation.
