SwiftCF

Using CoreFoundation based framework in Swift painlessly.

Wrapped frameworks:

• ☑ CoreFoundation
• ☑ CoreGraphics
• ☑ CoreText
• ☑ ImageIO
• ☑ IOKit
  • ☑ HID
• ☑ ApplicationServices
  • ☑ Accessibility (AXUIElement)
• ☐ CoreMedia
• ☐ CoreVideo
• ☐ CFNetwork
• ☐ Security
• ☐ CoreServices
• ☐ VideoToolbox
• ☐ SystemConfiguration

Usage

Dynamic casting to CoreFoundation types via the type-id mechanism.

import SwiftCF

let str: Any = "foo" as CFString

let s0 = str as? CFString
// ❗️ Conditional downcast to CoreFoundation type 'CFString' will always succeed

let s1: CFString = cfCast(str) // or
let s2 = cfCast(str, to: CFString.self) // or
let s3 = CFString.cast(str)
// ✅

Toll-Free-Bridging

let cfStr: CFString = .from("foo")
let nsStr: NSString = cfStr.asNS()
let str: String = cfStr.asSwift()

Convenient Extensions

let str = "foo" as CFString

str.length
// Replace CFStringGetLength(str)

CFStringTokenizer.create(string: str)
// Replace 😱 CFStringTokenizerCreate(kCFAllocatorDefault, str, CFRange(location: 0, length: CFStringGetLength(str)), kCFStringTokenizerUnitWord, CFLocaleGetSystem())

Swift Protocol Conformance

let arr = [1, 3.14, "foo"] as CFArray

for item in arr {
    // 😃 CFArray now conforms to RandomAccessCollection.
}
