How to check what a String starts with (prefix) or ends with (suffix) in Swift

Question

I\'m trying to test if a Swift string starts or ends with a certain value. These methods do not exist:

var str = \"Hello, playground\"
str.startsWith(\"Hello         


        

Answer 1

Prefix and Suffix Equality

To check whether a string has a particular string prefix or suffix, call the string’s hasPrefix(:) and hasSuffix(:) methods, both of which take a single argument of type String and return a Boolean value.
