I tried to debug my app on my phone running on 17.2. But I just got this error after upgrading to Xcode 15.1. Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.NG4V3R/extracted/Payload/myapp.app/Frameworks/SwiftyStoreKit.framework : 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. There is no developer certificate under that VPN & Device Management.
