How to combine or merge arrays in Swift? (Complete guide)

Hello everyone! I'm new to Swift and writing my first app. I've encountered what seems like a simple task: I have two arrays with user names, and I need to combine them into one single array.\n\nHere's what I've tried:\n\n```swift\nlet teamA = ["Anna", "Boris", "Victor"]\nlet teamB = ["Gleb", "Daria", "Elena"]\nlet mergedArray = teamA + teamB // this works, but is it correct?\n```\n\nBut I have a few questions:\n1. Is this the most correct way to combine arrays?\n2. What if the arrays have different types? For example, one array contains strings and another contains numbers?\n3. How to handle combining more than two arrays, for example, 5-10 of them?\n4. Is there a difference between combining arrays and merging them? I've heard Swift has a `joined()` method — does it do the same thing?
