How can I handle errors in my iOS app?

You can handle errors in iOS using do-catch blocks, optional handling, and error types. What specific errors are you facing?

I'm not sure how to use do-catch properly.

In Swift, you can wrap your code in a do block and catch specific errors. For example:

do {
    try someFunction()
} catch let error {
    print("Error: \(error)")
}```
This will catch any errors thrown by `someFunction`.

What if I want to handle multiple error types?

You can use multiple catch blocks to handle different error types separately. For example:

catch MyError.type1 {
    // Handle type1 error
} catch MyError.type2 {
    // Handle type2 error
}```
This way, you can provide specific handling for each error type.

Are there best practices for error handling in iOS?

Yes, some best practices include using custom error types, providing user-friendly error messages, and logging errors for debugging.
