Though this means that there might be phantom errors that are not real, but are caused by the dependency’s build failure.

If your deleted files are still being complained about “Build input files cannot be found”:

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.
