Developing along, no problems - and then suddenly:

Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.G47wHn/extracted/Payload/Dvn8.app : 0xe8008001 (An unknown error has occurred.)

Verify that the Developer App certificate for your account is trusted on your device. Open Settings on the device and navigate to General -> VPN & Device Management, then select your Developer App certificate to trust it.

—> On my Mac, there is no /var/installd directory.

—> On my device, there is no Developer App certificate in Settings -> General -> VPN & Device Management.

I have verified on developer.apple.com under Certificates, Identifiers & Profiles that my device‘s Device ID (UUID) as listed.

I have NO problem building & installing this app to my iPad, nor any problems installing other of my apps to this iPhone - it’s just this app on the phone that’s messed up.

I’ve restarted everything multiple times. I’ve cleared out both /Users/me/Library/Developer/Xcode/DerivedData/ as well as /Users/me/Library/MobileDevice/Provisioning Profiles/

I’ve turned off & back on Settings -> Privacy & Security -> Developer Mode

using macOS Version 14.0 (Build 23A5337a) Xcode 15.0 (22005) (Build 15A5229m)

Please help! I’m 100% blocked from releasing a new version of our app, which is 100% ready to upload!

I did so:

  1. Clean Project
  2. Delete Derrived Data
  3. Delete app on device
  4. Delete certificate from KeyChain

after that app installed

I'm going to post this in multiple places as I just went through this dance and NONE of the advice worked. iOS 17.3.1 and XCode15.2. I think the precipitating issue was that my provisioning profile expired.

I restarted, wiped DerivedData, created new certs, new profiles, double-checked the device was included in the list, had a happy thought when the device list needed its annual reset ... all the advice here and elsewehere didn't fix.

What DID seem to turn the corner was simply building a new app with XCode managing signing and running it on the device!

When I did that, before it deployed to the device, I got the Codesign auth popup on Mac so it could have access to the keychain.

After authorising and running that app from XCode, I was able to deploy my app to device!

Check you "Run Script" phases, if you preprocess some frameworks it may influence integrity of the outcome build. T
