Expression implicitly coerced from 'String?' to Any [duplicate]
I have some error like this "Expression implicitly coerced from String?
to Any
" this is my code :
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
FIRApp.configure()
FIRAuth.auth()?.signIn(withEmail: "[email protected]", password: "mypassword", completion: { (user, error) in
if (error != nil) {
print(user?.email)
}else {
print(error?.localizedDescription)
}
})
return true
}
Error in this line
print(user?.email)
And
print(error?.localizedDescription)
Please help me
The print
function requires a set of Any
parameters. String
is a Any
. In this case Xcode is telling you that it implicitly coerced the optional string into an Any
object (by transforming the String
value in Optional(value)
).
To avoid this warning, you can simply use a default value or unwrap the String?
print(user?.email ?? "User instance is nil")
print(user!.email)
