Carthage vs SPM differences

[Toke Refstrup]

So I'm currently migrating from Carthage to SPM. After doing so I started seeing crashes that looked to be related to PINCache, so i tested some more.

I made two projects one using PINCache with SPM and one with Carthage thats the only difference. They basically just have this code:

import UIKit
import PINCache

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        let cache = PINCache(name: "test")
        cache.setObjectAsync("test", forKey: "test", withAgeLimit: 666666)
    }
}

The one using Carthage seems to be working just fine however the one using SPM immediately throws this exception

What on earth am I doing wrong here? How can the functionality change based on if I use Carthage or SPM?

Both SPM and Carthage dependencies have this version numbers:

PINOperation at "1.2.1"
PINCache at "3.0.3"
