When accessing app group lots of errors about optionals

[poml88]

Hi, if I use this code in Xcode 15

let sdefaults = SecureDefaults(suiteName: "a")
        if !sdefaults.isKeyCreated {
            sdefaults.password = UUID().uuidString
        }
        sdefaults.set(password, forKey: "libre-direct.settings.password")
        sdefaults.synchronize()

I get quite some errors about optionals:

Value of optional type 'SecureDefaults?' must be unwrapped to refer to member 'isKeyCreated' of wrapped base type 'SecureDefaults'
Value of optional type 'SecureDefaults?' must be unwrapped to refer to member 'password' of wrapped base type 'SecureDefaults'
Value of optional type 'SecureDefaults?' must be unwrapped to refer to member 'set' of wrapped base type 'SecureDefaults'
Value of optional type 'SecureDefaults?' must be unwrapped to refer to member 'synchronize' of wrapped base type 'SecureDefaults'

When I use this extension:

extension SecureDefaults {
    static let sgroup = SecureDefaults(suiteName: stringSValue(forKey: "APP_GROUP_ID"))!
    
    static func stringSValue(forKey key: String) -> String {
        guard let value = Bundle.main.object(forInfoDictionaryKey: key) as? String else {
            fatalError("Invalid value or undefined key")
        }
        return value
    }
}

it does work.
