Let's say that you have the code
if stringValue == "ab" || stringValue == "bc" || stringValue == "cd" { // do something } Is there a way to shorten this condition or beautify it (preferably without using the switch statement)? I know that this code does NOT work:
if stringValue == ("ab" || "bc" || "cd") { // do something } I've seen some complex solutions on other languages, but they seem language specific and not applicable to Swift. Any solutions would be appreciated.

To check if a variable is equal to all of multiple values, use the logical AND (&&) operator to chain multiple equality comparisons. If all comparisons return true , all values are equal to the variable. Copied! We used the logical AND (&&) operator to chain multiple equality checks.
Use scatterplots to compare two continuous variables. Use scatterplot matrices to compare several pairs of continuous variables. Use side-by-side box plots to compare one continuous and one categorical variable. Use variability charts to compare one continuous Y variable to one or more categorical X variables.
To check if two strings are equal in Swift, use equal to operator == with the two strings as operands. The equal to operator returns true if both the strings are equal or false if the strings are not equal.
let valuesArray = ["ab","bc","cd"] valuesArray.contains(str) // -> Bool If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
