I want to check multiple string in if condition if are not nil and not empty.
for now i am doing like
func isSetupDone(token1: String?, token2: String?, token3: String?) -> Bool{
if token1 == nil || token1!.isEmpty || token2 == nil || token2!.isEmpty || token3 == nil || token3!.isEmpty {
return false
}
else{
return true
}
}
but i guess there should be better way of doing this in swift 5. Please suggest if any
You can add all Strings to an Array and call allSatisfy on that array.
func isSetupDone(token1: String?, token2: String?, token3: String?) -> Bool {
let tokens = [token1, token2, token3]
return tokens.allSatisfy { $0 != nil && $0?.isEmpty == false }
}
You can also merge the two conditions into a single one by optional chaining the optional strings, since $0?.isEmpty == false will evaluate to false in case $0 is nil.
func isSetupDone(token1: String?, token2: String?, token3: String?) -> Bool {
[token1, token2, token3].allSatisfy {$0?.isEmpty == false }
}
