Type Casting¶. var string = "12.2416" if let floatValue = Float (string) { print ("Float value = \(floatValue) ") } else { print ("String does not contain Float") } If the String contains a valid floating point value, then Swift will assign it to the floatValue constant which will be available within the if let scope. What does that mean? It means that if you initialize a variable with float value during declaration, you can skip telling the compiler that the variable is of Float type. Swift's string interpolation means you can convert all sorts of data – including integers – to a string in just one line of code: let str1 = "\(myInt)" However, the more common way is just to use the string initializer, like this: let str2 = String(myInt) When you define the function parameter, the function parameters cannot be modified inside the body. How to convert String to Double or Float in Swift, If the String contains a valid floating point value, then Swift will assign it to the floatValue constant which will be available within the if let scope. Int, Float, Double,String etc. Given a Float or a Double value: var value = 4.53978.
