Crash in iOS when calling `ProvidePreferenceLocals` referencing converting Long to Int

[PerrigoGames]

I'm experiencing a crash in my Compose Multiplatform application when I try to open my Settings screen. It seems to be coming from the call to ProvidePreferenceLocals.

This only happens in iOS (iOS 26.2 targets were tested); Android and Desktop targets do not crash.
First observed in Compose Preferences 2.1.0, but was also observed after upgrading to 2.1.1.
It doesn't seem to be related to the values I keep in the preferences, I went through and converted all instances of Longs being stored into Ints, but that didn't change the behavior.

v2.1.0

Uncaught Kotlin exception: kotlin.ClassCastException: class kotlin.Long cannot be cast to class kotlin.Int

[zhanghai]

I think the stacktrace is complaining about the opposite, this library is trying to cast a long into an int.

Did 2.0.0 work fine for you? If yes, then probably Kotlin changed how it bridges the iOS APIs. If not, probably I got it wrong from the beginning - I'm not really an iOS developer after all.

[PerrigoGames]

I didn't think to take the version back, but after trying 2.0.0, that seems to have the same crash:

Not sure how helpful they are since they're pretty much the same path.

Do you know how NSUserDefaults is supposed to work with integers (int v.s. long)?

i.e. If Obj-C or Swift code saves an int or long into it, will they be able to tell if it's an int or long upon reading? Or will it always be an int, or a long?

---

During my previous investigation (as a non-iOS dev randomly looking into docs/resources on the Internet), I was assuming that according to https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/ObjCRuntimeGuide/Articles/ocrtTypeEncodings.html , and I can't remember the exact reason but I was thinking we can't tell the difference between int and long for an NSNumber.

And I was following https://kotlinlang.org/docs/native-objc-interop.html#primitive-types to do the manual cast.

Perhaps I was assuming that an iOS app previously using NSUserDefaults could have saved an int and we'll read that out without being able to tell whether it's int or long.

The documentaion for NSNumber https://developer.apple.com/documentation/Foundation/NSNumber did say:

Your implementation of objCType must return one of “c”, “C”, “s”, “S”, “i”, “I”, “l”, “L”, “q”, “Q”, “f”, and “d”. This is required for the other methods of NSNumber to behave correctly.

UserDefaults Test.swiftpm.zip

I'm not much of an iOS developer either, but this is what I came up with. I put it into a Swift Playground to make it simple to run, but here's the gist:

func testUserDefaults() -> String {
    let defaults = UserDefaults.standard
    let intKey = "com.example.intKey"
    let longKey = "com.example.longKey"
    
    // Int
    let someInt: Int = 42
    defaults.set(someInt, forKey: intKey)
    
    let readInt: Int = defaults.integer(forKey: intKey)  // returns 0 if missing
    
    // "Long" on iOS/Swift is typically Int64 (or just Int, which is 64-bit on modern iOS devices)
    // There is no dedicated int64(forKey:), so read as NSNumber-compatible and convert.
    let someLong: Int64 = 9_223_372_036_854_775_000
    defaults.set(someLong, forKey: longKey)
    
    let readLong: Int64
    if let number = defaults.object(forKey: longKey) as? NSNumber {
        readLong = number.int64Value
    } else {
        readLong = 0 // default if missing or wrong type
    }
    
    return "Int = \(readInt), Long = \(readLong)"
}

We may not have 32-bit operating systems to worry about, but I suppose this would just be more guarded against such a situation.
