Swift Standard Library Optimization: Swift’s standard library is optimized for checking the emptiness of strings using .isEmpty. It efficiently determines whether the string has any characters without the need to count them explicitly. Performance Considerations: Using count to check emptiness could int...
Standard Library struct Int A signed integer value type. struct Double A double-precision, floating-point value type. struct Array An ordered, random-access collection. struct Dictionary A collection whose elements are key-value pairs. Swift Standard Library Solve complex problems and write high-perf...
Powerful and small library written inSwiftthat will allow you to create complex attributed strings. Easily chain Strings + SmartStrings to create the perfect style, and register substrings Tap Getures handlers. Features Powerful and intuitive APIs ...
Crotalus is an convenient and fast approach to create AttributedString in Swift. This library is inspired by colorize which is a ruby gem colorize string. If you would like to use chainable syntax in Objective-C use Typeset instead. With Crotalus With Cratalus, you can create attributed string...
The reversed() method reverses the given string. The reversed() method reverses the given string. Example var msg = "Learn Swift" // reverse msg var result = String(msg.reversed()) print(result) // Output: tfiwS nraeL reversed() Syntax The syntax of the
Swift makes base64 encoding and base64 decoding fairly straightforward. Gone are the days when you needed a third party library to handle such tasks. Remember that base64 encoding isn't a form of encryption. It won't help you protect the data you are sending or receiving....
You can find an alternative way for older Swift versions. Example Open Compiler import Foundation func randomAlphanumericString(_ length: Int) -> String { let letters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789" let randomString = (0..<length).map{ _ in String(letters....
1. Swift 的 Codable In a nutshell, Encoding is the process of transforming your own custom type, class or struct to external data representation type like JSON or plist or something else & Decoding is the process of transforming external data representation type like JSON or plist to your own...
Example: Swift removeAll() var text = "Remove Repeated Words" let remove: Set<Character> = ["e", "R", "o", "S"] text.removeAll(where: { remove.contains($0) }) print(text) // Output: mv patd Wrds In the above example, we have created a set named remove with characters that...
And there's no integer based String manipulation methods in Swift Standard Library. I can find some reasons why Swift team does not provide us sucheasiermethods. - Integer based offset or length may differ in each use case, byte (of some specific encoding), UTF-16 code unit, Unicode code...
