iOS/Swift: directly manipulate remote MySQL over SSH - ios

Question

is it possible to read, write, ... to/from a MySQL-database hosted on a remote server? I.e. can I connect to the database via SSH and directly make CRUD operations?
Is SSH possible/allowed in iOS, e.g. copying over images to a remote server etc.?

Answer 1

You could use a framework like NMSSH - see it here on Github.
Here is an usage example taken from a project by cagnulein:
var host = "your-host.com"
var username = "user"
var password = "pass"
var session = NMSSHSession(host: host, andUsername: username)
session.connect()
if session.connected == true {
session.authenticateByPassword(password)
if session.authorized == true {
NSLog("Authentication succeeded")
}
var error = NSErrorPointer()
var response = session.channel.execute("ls", error: error)
NSLog("List of my files %#", response)
}
session.disconnect()
Swift 4 & latest NMSSH version
do {
let host = "example.com"
let username = "user"
let password = "pass"
let session = NMSSHSession(host: host, andUsername: username)
session?.connect()
if session?.isConnected ?? false {
session?.authenticate(byPassword: password)
if session?.isAuthorized ?? false {
print("Authentication succeeded")
}
let response = try session?.channel.execute("ls")
print("List of my files:", response)
}
session?.disconnect()
} catch {
print(error)
}
