Swift language-interesting string connections, arrays, dictionaries

String Links: string Connection in swift language I find it very interesting, the variable connection needs to use the right slash, and the variable name to enclose "\ (variable name)", followed by the string concatenated with a comma ', ' separated

Array:

Var arr = ["Hello", "Adong", 100, 2, 6]

Println (arr)

Var arr1 = []//declaring an empty array

Var arr2 = string[] ()//declaration of an empty array, specific String type

Dictionary:

Var dict = ["Name": "Adong", "Age": "21"]

dict["sex"] = "male"//dict is a variable and can be dynamically assigned

println (dict)//Output The value of the entire dictionary

println (dict[1])//Output The value of the following table

println (dict["name"])//output the value of which key is specified
