SQLite.swift (Release 0.11.2) sample code is not working - ios

Question

I am trying to use SQLite.swift sample code but it is throwing an error.
First step I have done is to install it using cocoapods and it was successful. Then I have tried to test it in my app delegate where I declare import SQLite and I have added the below code in didFinishLaunchingWithOptions but it is showing an error.
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
let db = try Connection("path/to/db.sqlite3")
let users = Table("users")
let id = Expression<Int64>("id")
let name = Expression<String?>("name")
let email = Expression<String>("email")
try db.run(users.create { t in
t.column(id, primaryKey: true)
t.column(name)
t.column(email, unique: true)
})
return true
}
The error I am getting from this code line (let db = try Connection("path/to/db.sqlite3")) is "Errors thrown from here are not handled"
Is there anyone experiencing the same issue? I am using XCode 8.2.1 and Swift 3.0.

Answer 1

Your app needs to know what it should do when there is a runtime error. What you're missing is a do/catch clause or the throws keyword at your function declaration. For more details have a look at chapter "Error Handling" of the the Swift book.

Thanks to #martin-r for the solution. Here's the updated code.
Solution:
do {
let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0]
let db = try Connection("\(documentsPath)/db.sqlite3")
let users = Table("users")
let id = Expression<Int64>("id")
let name = Expression<String?>("name")
let email = Expression<String>("email")
try db.run(users.create { t in
t.column(id, primaryKey: true)
t.column(name)
t.column(email, unique: true)
})
} catch {
// Handle error
}
