Check empty string in Swift?

Question

In Objective C, one could do the following to check for strings:

if ([myString isEqualToString:@\"\"]) {
    NSLog(@\"m         


        

Answer 1

In Xcode 11.3 swift 5.2 and later

Use

var isEmpty: Bool { get } 

Example

let lang = "Swift 5"

if lang.isEmpty {
   print("Empty string")
}

If you want to ignore white spaces

if lang.trimmingCharacters(in: .whitespaces).isEmpty {
   print("Empty string")
}
