Emarcam 0.3.1

Maintained by iOSDevZone.

You want to add pod 'Emarcam', '~> 0.3' similar to the following to your Podfile:

target 'MyApp' do
  pod 'Emarcam', '~> 0.3'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try Emarcam

Getting started

Assuming you have integrated Emarcam into your project using your preferred method (CococaPods, Carthage, Swift Package Manager or manually), just import the module at the top of your file.

import Emarcam

Subscripting

Emarcam greatly simplifies subscripting strings by allowing you to use Ints as indices. For example:

let str = "Hello, playground!"
str[0] // "H"
str[1] // "e"
str[0..<4] // "Hell"
str[0...4] // "Hello"
str[6..<str.count] // " playground!"

Compare this to the same expressions in Swift 4.

str[str.startIndex]
str[str.index(after: str.startIndex)]
str[str.startIndex..<str.index(str.startIndex, offsetBy:4)]
str[str.startIndex...str.index(str.startIndex, offsetBy:4)]
str[str.index(str.startIndex, offsetBy:6)..<str.endIndex]

Replacing Substrings

The same simplified integer ranges can be used in the replacement methods. Here the Kanji ‘休’ is replaced with its pronunciation ‘やす’.

var ms0 = "お休みなさい"
let hiragana: [Character] = [ "や", "す" ]
ms0.replaceSubrange(1..<2, with: hiragana)
// おやすみなさい

Removing Substrings

Removal of substrings is also a happier experience.

var ms1 = "😭☠️☠️😀💀😀☠️☠️😡"
ms1.removeSubrange(0...2)          // ms1 = "😀💀😀☠️☠️😡"
ms1.remove(at: 1)                  // returns '💀' and ms1 = "😀😀☠️☠️😡"
ms1.removeSubrange(2..<ms1.count)  // ms1 = ""😀😀"

Methods Backported to Swift 3

Emarcam backports some Swift 4 goodness into Swift 3.

Drop

// MARK: - Non-mutating Removal (Backported)
public func dropFirst() -> SubstringType
public func dropFirst(_ n: Int) -> SubstringType
public func dropLast() -> SubstringType
public func dropLast(_ n: Int) -> SubstringType

Remove

// MARK: - Mutating Removal (Backported)
mutating func removeFirst() -> Character
mutating func removeFirst(_ n: Int)
mutating func removeLast(_ n: Int)
mutating func removeLast() -> Character
