Can't render camera preview on iOS with Objective-C

I trying to make a Native module to React Native using native camera api from objective C, but I can't render camera, I only can render the background set in layoutSubviews method.

My RNCameraManager.m file:

#import "RNCameraManager.h"#import <React/RCTViewManager.h>#import "RNCamera.h"@interface RNCameraManager : RCTViewManager@end@implementation RNCameraManagerRCT_EXPORT_MODULE(RNCameraManager)- (UIView *)view{  return [[RNCamera alloc] initWithBridge:self.bridge];}@end

My RNCamera.m file:

#import "RNCamera.h"#import <React/RCTUtils.h>#import <React/UIView+React.h>@interface RNCamera ()@property (nonatomic, weak) RCTBridge *bridge;@property (nonatomic, strong) AVCaptureSession *session;@property (nonatomic, strong) AVCaptureVideoPreviewLayer *previewLayer;@end@implementation RNCamera- (id)initWithBridge:(RCTBridge *)bridge{  if((self = [super init])) {    self.bridge = bridge;    self.session = [AVCaptureSession new];    self.sessionQueue = dispatch_queue_create("cameraQueue", DISPATCH_QUEUE_SERIAL);  }  return self;}- (void)layoutSubviews{  [super layoutSubviews];  self.previewLayer.frame = self.bounds;  [self setBackgroundColor:[UIColor redColor]];  [self.layer insertSublayer:self.previewLayer atIndex:0];}@end

When I call this method in React Native, I only get a Red Screen (beacause I set red to background color).

I set view size on react native render, (When I try to switch RN Camera to Maps, works perfectly, so the problem is time to actually render the camera and not the view)

My render result
