How to fix app won't install because integrity could not be verified

Jai Holloway 60

I have a MAUI app that I am trying to get installed on an iOS device, but I keep getting an "integrity could not be verified" error when installing the app. I have searched like mad but can't find any useful information to help me overcome this error.

What is interesting to note is that I have 2 provisioning profiles in the list under Xamarin -> iOS, I use the first provisioning profile to create the app archive, but only the second profile is available in the dropdown when trying to create the IPA file. I don't know what the problem could be and any help would be appreciated.

I have tried every combination of creating the archive but I always only get the second provisioning profile in creating the IPA file to select.

When archiving the app, you should select the distribution provisioning profile. Please follow the doc step by step- Publish a .NET MAUI iOS app for App Store distribution - .NET MAUI | Microsoft Learn

I keep getting an "integrity could not be verified" error when installing the app. How did you install the app on your device? via TestFlight, right? Do you add any iOS capabilities? Would you mind sharing the iOS entitlements with me?

It sounds like there might be a mismatch between the provisioning profiles used for archiving and creating the IPA file. Make sure both profiles are correctly configured and associated with the same app identifier. Also, try refreshing your profiles in Xcode to see if that helps. Hope this resolves the issue!

My entitlements.plist file is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

			<string>$(AppIdentifierPrefix)com.microsoft.adalcache</string>
		</array>
	</dict>
</plist>

As a note, there doesn't seem to be Keychain as an option on apple to select. I have no idea how to get this IPA to work.

How do you install it through testflight? I am very new to iOS development. This is my first MAUI app. What is strange is that I managed to get it installed before, but now it won't install at all.

Hello,

You are using App Groups service, so the additional provisioning is required to ensure that the app is code signed correctly.

You have to create a provisioning profile manually and select that provisioning profile.

About how to do this, please see iOS capabilities - .NET MAUI | Microsoft Learn

Best Regards,

Sorry, as I mentioned, I am new to this. What do you mean by App Groups Service? We have created a provisioning profile for this but we still can't get it signed. I am at a complete loss.

I can't comment anymore, as they have been turned off. What do you mean by App Group Services? We have created a provisioning profile, but we may have created it incorrectly. I am very, very new to MAUI and iOS development and am at a complete loss at the moment. I am not sure what to do to get this app signed.

keychain-access-groups this key means you are using the App Groups Service. If you don't need this feature, you can remove it.

Before we were using a development profile and the installed fine through iTunes. Is your provisioning profile type of distribution? Do you archive the app using distribution provisioning profile and then download the app via TestFlight?

It is used for MSAL, so I do need it. Is App Groups Service a capability when creating a provisioning profile?

App Group doesn't seem right. Honestly, I don't know enough about this to know what I am doing. Could you please explain what you mean by I am using app group service. I thought it was keychain access that I needed to configure.

It's not clear about your APP logic, App groups and keychain access groups aren’t mutually exclusive—you can use both in the same app.

Is App Groups Service a capability when creating a provisioning profile?

Yes, you can try adding the App Groups Service. See iOS capabilities - .NET MAUI | Microsoft Learn

Yes. Please see if there are some configurations or setup steps on MSAL docs.

I'm in a similar boat. @Jai Holloway did you make any progress with this?
