Can you reproduce the bug?
Yes, always
Reproduction Steps
Open the included project and click Get Sync Items
Version
10.28.5
What SDK flavour are you using?
Local Database only
Are you using encryption?
No, not using encryption
Platform OS and version(s)
iOS 15
Build environment
Xcode version: ... Dependency manager and version: ...
Here is the test project I created to reproduce the issue. I'm running this on M1 Pro MacBook Pro
This is an even simpler example. Seems like it fails any time you filter to a uuid using NSPredicate. It does work to use the new query method (as shown in this example project) but the NSPredicate fails
I've narrowed down to where the issue is:
RLMAccessor.mm: Line 991
realm::UUID RLMStatelessAccessorContext::unbox(id v) {
return RLMObjcToUUID(bridged<NSUUID>(v));
}
RLMAccessor.mm: Line 946
static T *bridged(__unsafe_unretained id const value) {
return [value isKindOfClass:[T class]] ? value : RLMBridgeSwiftValue(value);
}
RLMUtil.mm: Line 92
id RLMBridgeSwiftValue(__unsafe_unretained id value) {
if (!value || !RLMSwiftBridgeValue) {
return nil;
}
return RLMSwiftBridgeValue(value);
}
SchemaDiscovery.swift: Line 191
private static let runOnce: Void = {
RLMSwiftBridgeValue = { (value: Any) -> Any? in
// `as AnyObject` required on iOS <= 13; it will compile but silently
// fail to cast otherwise
if let value = value as AnyObject as? _ObjcBridgeable {
return value._rlmObjcValue
}
return nil
}
}()
The RLMSwiftBridgeValue returns nil because the line if let value = value as AnyObject as? _ObjcBridgeable fails
Hi @gbreen12 Thanks for the solid reproduction! We'll investigate the issue.
