Encountering the “This app could not be installed because its integrity could not be verified” error on your iPhone can be frustrating, especially when you are trying to install or update an app. This issue is often related to Apple’s strict app verification process. If the app’s certificate or signature fails to meet Apple’s security standards, iOS will block the installation.
Understanding the “This App Could Not Be Installed Because Its Integrity Could Not Be Verified” Error
When you attempt to install an app on your iPhone, iOS checks the app’s integrity to ensure it’s safe and hasn’t been tampered with. This verification ensures that the app originates from a trusted source. If the app fails this check, you’ll see variations of the error like:
- “This app could not be installed because its integrity could not be verified.”
- “App integrity could not be verified.”
- “Integrity could not be verified iOS.”
- “This app cannot be installed because its integrity.”
By having these errors mainly occur with apps downloaded from third-party sources or older apps that haven’t been updated to meet Apple’s security policies.
Why Does the Integrity Verification Fail?
There are several reasons why iOS shows the “This app could not be installed because its integrity could not be verified” error:
There are several reasons why iOS shows the “This app could not be installed because its integrity could not be verified” error:
- Untrusted Developer: The app developer may not be recognized by Apple, leading to verification failure.
- Expired or Invalid Certificate: The app’s certificate may have expired or been revoked.
- Outdated App Version: Apps that haven’t been updated for the latest iOS may fail the verification.
- Side-Loading Apps: Apps not downloaded from the official App Store often trigger this error due to Apple’s strict policies.
How to Fix “This App Could Not Be Installed Because Its Integrity Could Not Be Verified” Error
Now that we know the common causes, let’s explore the solutions.
1. Download the App from the Official App Store
The safest and easiest way to avoid the “app integrity could not be verified” error is by downloading apps directly from the official App Store. This guarantees that the app has passed Apple’s security checks.
- Search for the app: If it’s available on the App Store, download it from there rather than a third-party source to avoid verification issues.
2. Update the App to the Latest Version
Sometimes, the app you’re trying to install is outdated, causing the integrity check to fail. Ensure you’re downloading the latest version of the app.
- Check for updates: Older versions of apps may have expired certificates or outdated security protocols, leading to verification errors.
3. Manually Trust the App Developer
Also, if you’re trying to install an enterprise or third-party app (not from the App Store), you may need to manually trust the developer. Here’s how to do that:
- Go to Settings > General > Device Management (or Profiles & Device Management).
- Select the developer profile for the app.
- Tap Trust [Developer Name] to verify the app manually.
Once you do this, the error “This app could not be installed because its integrity could not be verified” should disappear, allowing the installation to complete.
4. Clear Cache and Reinstall the App
Corrupted or incomplete installation files can cause the app to fail verification. In this case, clearing the cache and reinstalling the app can help.
- Uninstall the app: Long press the app icon and select Delete App.
- Restart your iPhone: A reboot can clear any cached data or conflicts.
- Reinstall the app: Go to the App Store (or your source) and install the app again.
5. Check for iOS Software Updates
Whereas, Apple regularly updates iOS with new security features and fixes. Running an outdated version of iOS can sometimes lead to app integrity errors. Ensure your iPhone is up-to-date.
- Check for updates: Go to Settings > General > Software Update. If an update is available, download and install it.
6. Verify the App’s Certificate
For apps not downloaded from the App Store, check if the app’s certificate is valid. If the certificate has expired, you will see the “This app could not be installed because its integrity could not be verified” error. Contact the app developer and request them to renew the certificate.
- Ask the developer: They may need to update the app’s certificate to ensure it meets Apple’s security standards.
7. Switch to a Stable Internet Connection
A poor or unstable internet connection can disrupt the app verification process. Ensure that your internet connection is stable when installing or updating apps.
- Switch to Wi-Fi: If you’re using cellular data, try switching to a Wi-Fi connection for a stable download and verification process.
8. Reboot Your iPhone
Sometimes, a simple restart can fix minor bugs or glitches, including issues with app integrity verification.
- Restart your iPhone: Press and hold the power button, then slide to power off. Turn your device back on and try installing the app again.
9. Contact Apple Support
If none of the above solutions work, you may need to contact Apple Support for further assistance. There could be a deeper issue with your iPhone’s security settings or the verification process.
