i've just converted my little app but i've found this error: 'substring(from:)' is deprecated: Please use String slicing subscript with a 'partial range from' operator
my code is:
let dateObj = dateFormatterFrom.date(from: dateStringa) if dateObj != nil { cell.detailTextLabel?.text = dateFormatterTo.string(from:(dateObj!)) } else { let index = thisRecord.pubDate.index(thisRecord.pubDate.startIndex, offsetBy: 5) cell.detailTextLabel?.text = thisRecord.pubDate.substring(from: index) }

In Swift 4 you slice a string into a substring using subscripting. The use of substring(from:) , substring(to:) and substring(with:) are all deprecated.
Substrings. When you get a substring from a string—for example, using a subscript or a method like prefix(_:) —the result is an instance of Substring , not another string. Substrings in Swift have most of the same methods as strings, which means you can work with substrings the same way you work with strings.
In Swift, the first property is used to return the first character of a string.
Swift String dropFirst() The dropFirst() method removes the first character of the string.
Follow the below example to fix this warning: Supporting examples for Swift 3, 4 and 5.
let testStr = “Test Teja” let finalStr = testStr.substring(to: index) // Swift 3 let finalStr = String(testStr[..<index]) // Swift 4 let finalStr = testStr.substring(from: index) // Swift 3 let finalStr = String(testStr[index...]) // Swift 4 //Swift 3 let finalStr = testStr.substring(from: index(startIndex, offsetBy: 3)) //Swift 4 and 5 let reqIndex = testStr.index(testStr.startIndex, offsetBy: 3) let finalStr = String(testStr[..<reqIndex]) //**Swift 5.1.3 - usage of index** let myStr = "Test Teja == iOS" let startBound1 = String.Index(utf16Offset: 13, in: myStr) let finalStr1 = String(myStr[startBound1...])// "iOS" let startBound2 = String.Index(utf16Offset: 5, in: myStr) let finalStr2 = String(myStr[startBound2..<myStr.endIndex]) //"Teja == iOS" If you love us?
