While printing an array how to get rid of brackets from left and right?
var array = ["1", "2", "3", "4"]
println("\(array)") //It prints [1, 2, 3, 4]
var arrayWithoutBracketsAndCommas = array. //some code
println("\(arrayWithoutBracketsAndCommas)") //prints 1 2 3 4
You could do:
extension Array {
var minimalDescription: String {
return " ".join(map { "\($0)" })
}
}
["1", "2", "3", "4"].minimalDescription // "1 2 3 4"
With Swift 2, using Xcode b6, comes the joinWithSeparator
method on SequenceType
:
extension SequenceType where Generator.Element == String {
...
public func joinWithSeparator(separator: String) -> String
}
Meaning you could do:
extension SequenceType {
var minimalDescrption: String {
return map { String($0) }.joinWithSeparator(" ")
}
}
[1, 2, 3, 4].minimalDescrption // "1 2 3 4"
Swift 3:
extension Sequence {
var minimalDescription: String {
return map { "\($0)" }.joined(separator: " ")
}
}
