Issue Description:

I followed this guide on creating wrapped properties with user defaults:

https://www.vadimbulavin.com/advanced-guide-to-userdefaults-in-swift/

Now, I have LocalStorage class which will take this "Storage()" class at the end of the tutorial and then access that object's references to get the data from UserDefaults values. For some reason, when I set a string in my code, it no longer builds/compiles. It works for booleans. An example below:

// make shift example

struct LocalStorage{
    
    var storage: Storage

    init(storage: Storage){
       self.storage = storage
    }

    func ex(){
         storage.username = "travis" // will not compile... "Abort 6" 
         storage.aBoolValue = true // without line above, it will compile
     }

}

Thoughts? Also tested in a fresh project. It still does not compile. "Abort trap: 6"
