What is the difference between if let and guard let??

[@riffatkhan6006]

Hy! Bro how i can answer someone verbally if he asks me for difference between optional binding and optional chaining

[@Puneet843]

when to use 'if let' statement and 'guard let' statement.?

[@CodeCat15]

Sorry to respond to this so late, for some reason I am not getting notification of the comments. We can use guard..let when we have nested if statements, nested if..let are so ugly and have zero code readability. Let's say your function has one single if statement and in the else you are writing code to exit the function like "return false" or just "return" something like that then in that case i would use guard let because the else of the guard will automatically exit the function and that's the good use case to when you can use guard. In general I use if..let for single conditional checks, only when I have 3-4 if.let that's where I switch to guard let for better code readability. We should also know the variable declared in guard let is available even after the scope of guard so just be careful when you name guard variables, I usually name them like "guard_emailString" that way I know that this variable is coming from a guard statement and is not a global variable. Hope this answers your question, If not let me know we can discuss it further and once again I am sorry I did not see this question earlier.

@@CodeCat15 I used to use 'guard let' and 'if let' statement in my code but I wasn't clear before when to use both. But now I'm clear. Thank you.
