Pattern: Tuple has too many members
Issue: -
Tuples shouldn't have too many members. Create a custom type instead.
Examples of correct code:
let foo: (Int, Int)
let foo: (start: Int, end: Int)
let foo: (Int, (Int, String))
func foo() -> (Int, Int)
func foo() -> (Int, Int) {}
func foo(bar: String) -> (Int, Int)
func foo(bar: String) -> (Int, Int) {}
func foo() throws -> (Int, Int)
func foo() throws -> (Int, Int) {}
let foo: (Int, Int, Int) -> Void
let foo: (Int, Int, Int) throws -> Void
func foo(bar: (Int, String, Float) -> Void)
func foo(bar: (Int, String, Float) throws -> Void)
var completionHandler: ((_ data: Data?, _ resp: URLResponse?, _ e: NSError?) -> Void)!
func getDictionaryAndInt() -> (Dictionary<Int, String>, Int)?
func getGenericTypeAndInt() -> (Type<Int, String, Float>, Int)?Examples of incorrect code:
↓let foo: (Int, Int, Int)
↓let foo: (start: Int, end: Int, value: String)
↓let foo: (Int, (Int, Int, Int))
func foo(↓bar: (Int, Int, Int))
func foo() -> ↓(Int, Int, Int)
func foo() -> ↓(Int, Int, Int) {}
func foo(bar: String) -> ↓(Int, Int, Int)
func foo(bar: String) -> ↓(Int, Int, Int) {}
func foo() throws -> ↓(Int, Int, Int)
func foo() throws -> ↓(Int, Int, Int) {}
func foo() throws -> ↓(Int, ↓(String, String, String), Int) {}
func getDictionaryAndInt() -> (Dictionary<Int, ↓(String, String, String)>, Int)?
