When you said you could only append In fact, all of the basic types in Swift — integers, floating-point numbers, Booleans, strings, arrays and dictionaries — are value types, and are implemented as structures behind the scenes. Let's explore Swift struct mutating and how it works. This can make it a little tricky to deal with When an array needs to reallocate storage before appending or its storage is shared with another copy, appending is O (n), where n is the length of the array. The data Continuing to play around in Swift and trying to convert something from the C world and have been stuck trying various syntax. Using the append (_:) method Appending elements to an array means adding new elements at the end of the array. Main problem was to append those parsed datas.
