Case-sensitive and Case-Insensitive sorting

There are two types of alphabetical sorting.

Case-sensitive

Capital letters are prioritised.

• Lemon
• Banana
• apple

Case-insensitive

No prioritisation, pure alphabetical sorting.

• apple
• Banana
• Lemon

We can achieve this compare and caseInsensitiveCompare in Array sorting.

-----------------------------------------------------------------------------------------

let arr = ["Lemon", "Mango", "apple", "banana", "Grapes"]

let sortedArr = arr.sorted { $0.compare($1) == .orderedAscending }

let sortedCaseInsensitiveArr = arr.sorted { 

           $0.caseInsensitiveCompare($1) == .orderedAscending }

sortedArr ["Grapes", "Lemon", "Mango", "apple", "banana"]

sortedCaseInsensitiveArr ["apple", "banana", "Grapes", "Lemon", "Mango"]
