Task is for “fire-and-forget” use cases, which means you don’t need to handle the result when it’s done processing:

Task {
    await fetchData(for: user)
}

Async let is for parallel processing where you do have to process the results:

async let a = callA()
async let b = callB()
let results = await a + b

And how to only create a table if it doesn’t already exist: as with sqlite, use ifNotExists:

db.create(table: "todo", ifNotExists: true) { t in
    t.autoIncrementedPrimaryKey("id")
    t.column("name", .text).notNull()
}

With the example of GRDB, a lightweight sqlite wrapper:

class DbManager {
    static let sharedInstance = DbManager()

    var dbPath: String!  <--- !!!
    var dbQueue: DatabaseQueue!

    private init() {
        do {
            dbQueue = try connectToDatabase()
            try createTable()
        } catch {
            print(error)
        }
    }
}

Right here: add through pasting a github URL. All done.

I love it when there’s an official way of managing packages. The evolution of even package management systems are just too much.

And how to uninstall: from the +/- button here. Not as friendly. Why couldn’t they have added a “remove package” option on the leftnav?

This happens after moving the swift files around.

Solution: simply quit Xcode and reload so that it can re-source the new location of the files.

Or command + B to rebuild. Sometimes those formatting errors are just not caught up and not rebuilt yet.
