I am not sure how to debug it because its working fine on Simulator and it works fine for 10 seconds on actual device but after 10 seconds it crashes Here is the crash log Exception Type:	EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Exception Note:	EXC_CORPSE_NOTIFY Triggered by Thread:	1 Last Exception Backtrace: 0	 CoreFoundation								 0x1ac1ca5ac __exceptionPreprocess + 220 (NSException.m:199) 1	 libobjc.A.dylib							 0x1c02b842c objc_exception_throw + 60 (objc-exception.mm:565) 2	 ZFunds												 0x100d1bb8c RCTFatal + 668 (RCTAssert.m:146) 3	 ZFunds												 0x100d955e4 -[RCTExceptionsManager reportFatal:stack:exceptionId:suppressRedBox:] + 492 (RCTExceptionsManager.mm:64) 4	 ZFunds												 0x100d9601c -[RCTExceptionsManager reportException:] + 1536 (RCTExceptionsManager.mm:135) 5	 CoreFoundation								 0x1ac1cf5d4 invoking_ + 148 6	 CoreFoundation								 0x1ac0aa9e8 -[NSInvocation invoke] + 448 (NSForwarding.m:3389) 7	 CoreFoundation								 0x1ac0aafa4 -[NSInvocation invokeWithTarget:] + 80 (NSForwarding.m:3495) 8	 ZFunds												 0x100d4a580 -[RCTModuleMethod invokeWithBridge:module:arguments:] + 460 (RCTModuleMethod.mm:569) 9	 ZFunds												 0x100d4c714 facebook::react::invokeInner(RCTBridge*, RCTModuleData*, unsigned int, folly::dynamic const&) + 244 (RCTNativeModule.mm:108) 10	ZFunds												 0x100d4c478 operator() + 44 (RCTNativeModule.mm:73) 11	ZFunds												 0x100d4c478 invocation function for block in facebook::react::RCTNativeModule::invoke(unsigned int, folly::dynamic&&, int) + 88 (RCTNativeModule.mm:65) 12	libdispatch.dylib						 0x1abdc6fd0 _dispatch_call_block_and_release + 32 (init.c:1454) 13	libdispatch.dylib						 0x1abdc8ac8 _dispatch_client_callout + 20 (object.m:559) 14	libdispatch.dylib						 0x1abdcfc08 _dispatch_lane_serial_drain + 580 (inline_internal.h:2548) 15	libdispatch.dylib						 0x1abdd0734 _dispatch_lane_invoke + 408 (queue.c:3862) 16	libdispatch.dylib						 0x1abdda528 _dispatch_workloop_worker_thread + 708 (queue.c:6590) 17	libsystem_pthread.dylib			 0x1f40bb908 _pthread_wqthread + 276 (pthread.c:2193) 18	libsystem_pthread.dylib			 0x1f40c277c start_wqthread + 8 Thread 0 name: Thread 0: 0	 libsystem_kernel.dylib				 0x00000001d8308dd0 mach_msg_trap + 8 1	 libsystem_kernel.dylib				 0x00000001d8308184 mach_msg + 76 (mach_msg.c:103) 2	 CoreFoundation								 0x00000001ac146cf8 __CFRunLoopServiceMachPort + 380 (CFRunLoop.c:2641) 3	 CoreFoundation								 0x00000001ac140ea8 __CFRunLoopRun + 1216 (CFRunLoop.c:2974) 4	 CoreFoundation								 0x00000001ac1404bc CFRunLoopRunSpecific + 600 (CFRunLoop.c:3242) 5	 GraphicsServices							 0x00000001c2c52820 GSEventRunModal + 164 (GSEvent.c:2259) 6	 UIKitCore										 0x00000001aeaed164 -[UIApplication _run] + 1072 (UIApplication.m:3270) 7	 UIKitCore										 0x00000001aeaf2840 UIApplicationMain + 168 (UIApplication.m:4739) 8	 ZFunds												 0x0000000100c4d4e4 main + 88 (main.m:7) 9	 libdyld.dylib								 0x00000001abe07e40 start + 4 Thread 1 name: Thread 1 Crashed: 0	 libsystem_kernel.dylib				 0x00000001d832c98c __pthread_kill + 8 1	 libsystem_pthread.dylib			 0x00000001f40bac74 pthread_kill + 272 (pthread.c:1375) 2	 libsystem_c.dylib						 0x00000001b5302c34 __abort + 116 (abort.c:147) 3	 libsystem_c.dylib						 0x00000001b5302bc0 abort + 116 (abort.c:118) 4	 libc++abi.dylib							 0x00000001c03b7e24 abort_message + 132 (abort_message.cpp:76) 5	 libc++abi.dylib							 0x00000001c03a9434 demangling_terminate_handler() + 308 (cxa_default_handlers.cpp:67) 6	 libobjc.A.dylib							 0x00000001c02b8710 _objc_terminate() + 132 (objc-exception.mm:701) 7	 ZFunds												 0x0000000100e50c24 CLSTerminateHandler() + 344 (CLSException.mm:310) 8	 libcabi.dylib							 0x00000001c03b72a8 std::terminate(void (*)()) + 20 (cxa_handlers.cpp:59) 9	 libc++abi.dylib							 0x00000001c03b7234 std::terminate() + 44 (cxa_handlers.cpp:88) 10	libdispatch.dylib						 0x00000001abdc8adc _dispatch_client_callout + 40 (object.m:562) 11	libdispatch.dylib						 0x00000001abdcfc08 _dispatch_lane_serial_drain + 580 (inline_internal.h:2548) 12	libdispatch.dylib						 0x00000001abdd0734 _dispatch_lane_invoke + 408 (queue.c:3862) 13	libdispatch.dylib						 0x00000001abdda528 _dispatch_workloop_worker_thread + 708 (queue.c:6590) 14	libsystem_pthread.dylib			 0x00000001f40bb908 _pthread_wqthread + 276 (pthread.c:2193) 15	libsystem_pthread.dylib			 0x00000001f40c277c start_wqthread + 8
