defer swift – what is defer in swift ?

It’s similar to the finally{} black used in C++ and Java. That means the code in defer will run anyways no matter what.

try{
}
catch{
    // more than one catch can be
}
defer{
   // code you want to run
}

try{

}

catch{

// more than one catch can be

}

defer{

// code you want to run

}
