There is a timing issue when reloading the bridge (in dev mode) and the tear down of the TurboModules. This causes `Instance` to never get freed, hence the "bridge" isn't cleaning up properly. The side effect can be bogus error saying that it's unable to find a module.
To address this, JSCallInvoker should just take in weak_ptr<Instance>.

Summary:
If a NativeModule method requires an optional boolean argument, our codegen translates those optional booleans into `NSNumber*` instead of `BOOL`. The reason why is probably because this is the closest object analogue to `BOOL` in Objective C. The same boxing occurs with numbers. If the type of a number argument in JavaScript is optional, we'll map it to the `NSNumber*` Objective C type instead of `double`. Our existing TurboModules argument conversion code would not take this behaviour into account. Therefore, we'd try to insert a `BOOL` where the `NSInvocation` would expect a `NSNumber*`. This, in turn, would cause the app to crash. (Why would it crash at the point of NSInvocation retainArguments, I'm still not sure).
Our flow typechecking ensures that if the type of a method argument is a boolean, we pass in a boolean. Therefore, on the Native side, if we detect a boolean, we can check the type of the Native argument to see whether we should box the primitive. If the native argument type is an object, then we know it has to be an `NSNumber*` in both cases, so we simply wrap the `BOOL` or `double` in a `NSNumber*`.

Summary: When calling into JS (e.g. promise resolve/reject, callback) in TurboModule, we bypass the bridge's message queue. At times this causes race condition, where there are a bunch of pending UI operations (in RCTUImanager) waiting to be flushed, but nothing adds calls to the message queue. Usually tapping the screen will trigger the flush because we're sending down touch events to JS.

Summary:
In D14571128, we made it so that when a JS object's property was `undefined`, we wouldn't insert that property into the corresponding NSDictionary. Here are two important observations about that diff:
1. ALL JS `null`s were now being converted to `NSNull`, and JS `undefined`s were now being converted to `nil`.
2. If a JS object's property was explicitly `null`, then we'd insert `NSNull` into the corresponding dictionary.
Considering that when a property doesn't exist in a `NSDictionary`, property access returns `nil`, I've made it so that if a JS object's property is either `null` or `undefined`, then we simply do not insert it in the corresponding `NSDictionary`. Also, I've reverted #1 and made it so that `undefined` and `null` always map to the ObjC `nil`.
This shouldn't unfix the problem that D14571128 was trying to fix.
Here's my understanding of the problem that D14571128 was trying to fix (to make sure I'm not breaking something by this diff).
This method was invoked from JS.
```
RCT_EXPORT_METHOD(logEvents:(NSDictionary *)events)
{
RCTAssert(events, @"You should provide events for logger");
[[NSNotificationCenter defaultCenter] postNotificationName:@"FBReactPerfLoggerDidReceiveEventsNotification"
object:nil
userInfo:@{@"FBReactPerfLoggerUserInfoPerfEventsKey" : [events copy]}];
}
```
The above dispatch calls into this method, which appends `events` into `_pendingJSPerfEvents`.
```
- (void)reactPerfLoggerDidReceiveEvents:(NSNotification *)notification
{
NSDictionary *events = notification.userInfo[@"FBReactPerfLoggerUserInfoPerfEventsKey"];
if (events) {
dispatch_async(_eventQueue, ^{
if (self->_sessionData.perfLoggerFlagId != nil) {
if ([self processJSPerfEvents:events]) {
[self reportMetricsIfFinished];
}
} else {
[self->_pendingJSPerfEvents addObject:events];
}
});
}
}
```
Then, in `_processJSPerfEvents`, we do the following (link: https://fburl.com/tr4wr2a7):
```
NSNumber *actionId = events[@"actionId"];
if (actionId) {
self->_sessionData.actionId = actionId;
}
```
So, if `undefined` or `null` was passed in as the `actionId` property of the `events` JS object in `FBReactPerformanceLogger logEvents:`, then we'd default the `NSDictionary` to have `NSNull` in the corresponding property. This is bad because we had this line in FBReactWildePerfLogger (link: https://fburl.com/2nsywl2n): `actionId ? [actionId shortValue] : PerfLoggerActions.SUCCESS`. Essentially, this is the same problem that my diff is trying to fix.

Summary:
With our current infra, we support automatic conversion of method arguments using `RCTConvert`.
```
RCT_EXPORT_METHOD(foo:(RCTSound*) sound)
{
//...
}
```
```
interface RCTConvert (RCTSound)
+ (RCTSound *) RCTSound: (NSDictionary *) dict;
end
implementation RCTConvert (RCTSound)
+ (RCTSound *) RCTSound: (NSDictionary *) dict
{
//...
}
end
```
```
export interface Spec extends TurboModule {
+foo: (dict: Object) => void,
}
```
With this setup, when we call the foo method on the TurboModule in JS, we'd first convert `dict` from a JS Object to an `NSDictionary`. Then, because the `foo` method has an argument of type`RCTSound*`, and because `RCTConvert` has a method called `RCTSound`, before we invoke the `foo` NativeModule native method, we first convert the `NSDictionary` to `RCTSound` using `[RCTConvert RCTSound:obj]`. Essentially, if an argument type of a TurboModule method is neither a primitive type nor a struct (i.e: is an identifier), and it corresponds to a selector on `RCTConvert`, we call `[RCTConvert argumentType:obj]` to convert `obj` to the type `argumentType` before passing in `obj` as an argument to the NativeModule method call.
**Note:** I originally planned on using `NSMethodSignature` to get the argument types. Unfortunately, while the Objective C Runtime lets us know that the type is an identifier, it doesn't inform us which identifier it is. In other words, at runtime, we can't determine whether identifier represents `RCTSound *` or some other Objective C class. I figure this also the reason why the old code relies on the `RCT_EXPORT_METHOD` macros to implement this very same feature: https://git.io/fjJsC. It uses `NSMethodSignature` to switch on the argument type, and then uses the `RCTMethodInfo` struct to parse the argument type name, from which it constructs the RCTConvert selector.
One caveat of the current solution is that it won't work work unless we decorate our TurboModule methods with `RCT_EXPORT_METHOD`.

Summary:
Before invoking TurboModule ObjC methods, we loop through all the arguments and transform them from `jsi::Value` to ObjC data structures. `jsi::Value`s that represent JS Objects get converted to `NSDictionary`s in ObjC. This isn't good enough because `NSDictionary` isn't typed. What we really need is a C/C++ struct that represents the type of the JS Object.
Therefore, for every argument of a TurboModule method that is a JS Object, this diff allows you to specify a method on `RCTCxxConvert` (which you have to declare and implement) that transforms that type of JS Object into something else. Basically, with the changes in this diff, we'll be able to transform JS Objects into C++ struct instances, which gives us type safety for JS Object method argumetns to TurboModule functions.
I modified the codegen to also create a mapping from NativeModule method name => argument num => `RCTCxxModule` conversion selector. This way, the FB codegen that generates the `RCTCxxConversion` function also informs our TurboModule system which conversion function to use before we call the method requiring complex argument. I just had to extend the `ObjCTurboModule` class to accomplish this.
The old system relies on the additional method generated by `RCT_EXPORT_METHOD` macro. It takes the written code, does string processing on it to parse the type of the struct arguments, and then replaces all instances of `::` with `_`. Super hacky. I didn't take this approach because it seemed unnecessarily hacky brittle.
The other approach I considered was to try to use reflection to infer the type of the struct at runtime. We'd have to do a bit of string processing and concat the TurboModule class name with the struct type. The solution would be simpler because it'd only modify the objective C and it wouldn't touch the Codegen system. **Edit:** I implemented it here: D14513078. The one downside of this design is that the name of the conversion function is individually constructed in two different locations in the code (i.e: no source of truth for this name). The other downside is that we have to rely on `RCTBridgeModuleNameForClass`, which we want to eliminate. This also computationally more expensive since it requires string processing/regex parsing and additional reflection. Therefore, we decided to move on with the current solution.
