How to convert String to Float in Swift - Step by Step Examples

How to convert String to Float in Swift ?

To convert a string to float in Swift, you can use the 'Float()' initializer.

In this example,

We create a string constant str1 with a value of "3.14".
We use the Float() initializer to convert the string to a float and store the result in a variable float1.
Finally, we print the float value float1.

// Convert "3.14" String to Float
let str1: String = "3.14"
if let float1 = Float(str1) {
    print("Float value is: \(float1)")
}

Float value is: 3.14

In this example,

We create a string constant str2 with a value of "10.5".
We use the Float() initializer to convert the string to a float and store the result in a variable float2.
Finally, we print the float value float2.

// Convert "10.5" String to Float
let str2: String = "10.5"
if let float2 = Float(str2) {
    print("Float value is: \(float2)")
}

Float value is: 10.5
