FunctionalSwiftKit
Example
To run the example project, clone the repo, and run pod install from the Example directory first.
Using
Condition
- You can use this instead of condition statement according to functional programming paradigm.
- Ensures thread safety.
- It is simple.
- Global variable.
Using single condition statement
if <<true or false>> {
} else if <<true or false>> {
} else {
}condition
.if(<<true or false>>) {}
.elseif(<<true or false>>) {}
.else {}Using multiple condition statements with chaining
if <<true or false>> {
} else if <<true or false>> {
} else {
}
if <<true or false>> {
} else if <<true or false>> {
} else {
}condition
.if(<<true or false>>) {}
.elseif(<<true or false>>) {}
.else {}
.if(<<true or false>>) {}
.elseif(<<true or false>>) {}
.else {}Array extension
- Here are some frequently used functions with array.
// Sample struct
struct Model: Hashable {
let uid: String
var hashValue: Int { return uid.hashValue }
static func ==(lhs: Model, rhs: Model) -> Bool {
return lhs.uid == rhs.uid
}
}Using function 'grouped' with strings
let source = ["A", "A", "B", "C"]
let grouped = source.grouped { $0 }
// print -> ["A": ["A", "A"], "B": ["B"], "C": ["C"]]Using function 'grouped' with structs
let source = [Model(uid: "A"), Model(uid: "A"), Model(uid: "B"), Model(uid: "C")]
let grouped = source.grouped { $0.uid }
// print -> ["A": [Model(uid: "A"), Model(uid: "A")], "B": [Model(uid: "B")], "C": [Model(uid: "C")]]Using function 'subtracted'
let source = [Model(uid: "A"), Model(uid: "B")]
let other = [Model(uid: "A")]
let subtracted = source.subtracted(other)
// print -> [Model(uid: "B")]Using function 'uniqued'
let source = [Model(uid: "A"), Model(uid: "A"), Model(uid: "B"), Model(uid: "B")]
let uniqued = source.uniqued()
// print -> [Model(uid: "A"), Model(uid: "B"), Model(uid: "C")]Optional extension
- You can use unwrap of Optional instead of map when you don't need return element.
import FunctionalSwiftKit
func testUnwrap() {
let string: String? = "string"
string.unwrap { <<your function for execution>>($0) }
