How to fix fastlane [Xcodeproj] Unknown object version (56). error?

I'm trying to build & archive iOS app using fastlane. But it always fails with this error:

[09:49:04]: Couldn't automatically detect the provisioning profile mapping
[09:49:04]: Since Xcode 9 you need to provide an explicit mapping of what
[09:49:04]: provisioning profile to use for each target of your app
[09:49:04]: [Xcodeproj] Unknown object version (56).

This is my lane:

clear_derived_data
unlock_keychain(password: keychain_password)
gym(scheme: "Staging")

Also tired this instead of a simple gym():

build_ios_app(scheme: "Staging",
              clean: true,
              xcargs: "-allowProvisioningUpdates")

Tired to specifically set provisioning profile mapping, but got this contradicting error message...

[09:26:39]: Couldn't automatically detect the provisioning profile mapping
[09:26:39]: Since Xcode 9 you need to provide an explicit mapping of what
[09:26:39]: provisioning profile to use for each target of your app
[09:26:39]: [Xcodeproj] Unknown object version (56).
[09:26:39]: Detected provisioning profile mapping: {:"*.staging"=>"Jenkins", :"*.dev"=>"Jenkins"}

NOTE: The project doesn't use any cocoapods, only SPM. Xcode version: 14.2

Solution

This could honestly be several different issues, but most likely you will need to manually set the correct provisioning profiles in Xcode like this (automatically manage signing is turned off):

I'm assuming you are using Fastlane match for signing. Also make sure to do this for each target (i.e. any Share Extensions, Today Widgets, etc.)
