Description

The try! operator should not be used because it forces execution of potentially failing code without proper error handling. If the call does throw an error, the program will crash immediately, leading to unpredictable behavior and poor maintainability. Instead, use try? with optional binding or the full do–catch syntax to safely handle errors and keep the code resilient.

Non-Compliant Code Examples

//
//
//
let myvar = try! dangerousCode(foo);  // Noncompliant
// ...

Compliant Code Examples

guard let myvar = try? dangerousCode(foo) else {
  // handle error
}

// or

if let myvar = try? dangerousCode(foo); {
  // ...
} else {
  // handle error
}

// or

do {
  let myvar = try dangerousCode(foo)
  // ...
} catch {
  // handle error
}
