Print unicode character from variable (swift)

Question

I have a problem I couldn\'t find a solution to. I have a string variable holding the unicode \"1f44d\" and I want to convert it to a unicode character

Answer 1

You cannot use string interpolation in Swift as you try to use it. Therefore, the following code won't compile:

let charAsString = "1f44d"
print("\u{\(charAsString)}")

You will have to convert your string variable into an integer (using init(_:radix:) initializer) then create a Unicode scalar from this integer. The Swift 5 Playground sample code below shows how to proceed:

let validCodeString = "1f44d"
let validUnicodeScalarValue = Int(validCodeString, radix: 16)!
let validUnicodeScalar = Unicode.Scalar(validUnicodeScalarValue)!
print(validUnicodeScalar) //
