Proxyman has this nice menu under “Certificate” where you can select configuration for either physical device or simulators:

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)
        }
    }
}
