Does anyone know of an easy way to add a single backslash () to an NSString in Objective-C? I am trying to add a backslash between each byte of addresses. But after adding and printing the output is not coming as expected. Output: "<IpAddress 0x00000002834809d0>" = { FourByteAddress = "0/\0/\0/\0"; }; Expected: "<IpAddress 0x00000002834809d0>" = { FourByteAddress = "0\0\0\0"; };

Hi team, We have developed one IoT project in that we have used apple's core database for storing all app-related settings, IoT device settings. In that we are facing some unusual crash (EXC_BAD_ACCESS) whenever we are performing saving, retrieving & updating operations it's causing random issues. So please help me out to fix this issue.
