These are formatted so you can copy the code straight into your Swift Playground files.

//create an empty array containing String types

var swift3Array = [String]()

swift3Array.append("Tutorials")

swift3Array.append("More Tutorials")

//remove an item

swift3Array.remove(at: 0)  //remove first item

//remove everything

swift3Array.removeAll()

//add stuff back...

swift3Array = ["CartoonSmart.com" , "Shameless Plug", "Best Tutorials for Swift 3"]

// check if the array has a specific thing...

for name in swift3Array {

    //for loop iterates through all Strings in the array

    if (name == "CartoonSmart.com") {

        // found the one we are looking for

        print("found")

        break

    }

    

}

// check if a specific index equals something

if ("Best Tutorials for Swift 3" == swift3Array[2] ) {

    

    // remember the 2 in swift3Array[2]  means that actually the third item in th array since indexing starts at 0

     print("true dat")

}
