#ifndef OCCatch_h
#define OCCatch_h

// add the code below to your -Bridging-Header.h
 
/**
 #import "OCCatch.h"
 */

//   How to use it in Swift?
/**
 let exception = tryBlock {
        let statusBar = UIApplication.shared.value(forKey: "statusBar") as? UIView
        //......
    }
  if let exception = exception {  
    print("exception: \(exception)")
  }  
*/

#import <Foundation/Foundation.h>

NS_INLINE NSException * _Nullable tryBlock(void(^_Nonnull tryBlock)(void)) {
    @try {
        tryBlock();
    }
    @catch (NSException *exception) {
        return exception;
    }
    return nil;
}

#endif /* OCCatch_h */

hello sir ,
can u explain me why we use this bridge file

Hi @sukh1993,

The reason is that in Swift project, sometimes the crash happens in the Objective-C side, we cannot use try { } catch { } to catch Objective-C crash. In that case we have to use a Objective-C wrapper to catch it.
For example: https://stackoverflow.com/questions/44167577/using-private-api-to-read-wifi-rssi-value/48083845?noredirect=1#comment88290822_48083845
